Diy grass trimmer attachment

For many summer residents, a grass trimmer has long become a familiar and almost irreplaceable technique. But it is not always possible to purchase a model that meets all needs. It happens that the grass trimmer copes with fresh young vegetation easily, but there is a desire to clear a place behind the fence or along the driveway, and the tall matured grass turns out to be too tough for the technique.

We offer the option of self-manufacturing grass trimmer attachments from simple, almost improvised, tools. You will need a metal perforated plate (100mm x 240mm), two hacksaw blades for metal, 4 screws and 4 M5 nuts, 4 washers and 4 enlarged washers. From a safety point of view, hacksaw blades should not be completely hardened.

The most difficult part in making a nozzle is to symmetrically mark and make holes for the knives and the grass trimmer shaft. That is why a ready-made perforated plate is chosen.

First you need to make the base of the nozzle. To do this, cut a square with a side of 100 mm from a metal plate with an angle grinder. You need to mark it in such a way that there is a hole exactly in the center (at the intersection of the diagonals). To do this, measure a distance of 50 mm from the center of the selected hole perpendicular to the short side of the plate and outline the cutting line for cutting.

Cut off the excess and get a square of 100 mm x 100 mm. Now you need to round the corners a little and drill the center hole for the grass trimmer shaft.

We cut the canvases for metal, measuring 8 cm from each end.We get four blanks with ready-made holes.

These blanks need to be shaped like knives. To do this, we outline the cut line by eye (special accuracy is not required), fasten all four blanks together and grind off the excess.

As a result, we get knives of the same weight and size, they can be sharpened a little on one side. Now all parts of the homemade grass trimmer attachment are ready, you can start assembling.

Put a small washer on the screw and insert it into the corner hole. We put on the knife from above, placing the sharpened side in the direction of rotation of the grass trimmer shaft. This is followed by a large washer and a nut that is not tightened so that the knife rotates freely. We attach the other three knives in the same way.

The end of the screw must be riveted so that the nut does not fly off.

The attachment is ready. It is installed with nuts to the ground and fixed in the same way as the three-blade knife that comes with the trimmer. When colliding with a stone, the knives fold and go inside a little.

Without accepting any of the sides of this sharp (literally and figuratively) discussion, let me show you one of the latest models of brushcutters from the German company Robert Bosch. It provides for both a deflecting knife and an arcuate bracket, which excludes the “striking” of the knife on objects not foreseen by mowing. I show the general view of the brushcutter and the knife itself, in two positions. General view of brushcutters

Knife in a deflected state

Folded knife

Good evening everyone! Exactly three years have passed since the discussion of the “acute” problem for the grass trimmer. Over the past 1000 days, a clear picture has emerged: “Glory to the author, the craftsman, who conducts an experiment on himself to reach the yield point of the metal from which these knives are made. He has every right to risk his own health. ” Nowadays in stunt films you can often see a frvza. “Do not try to repeat the movie stunts that were performed by professional stuntmen.” The very first article was supposed to end with approximately the same phrase: “Dear summer residents. This is my personal experiment. If you are not sure of your locksmith’s abilities, please do not repeat it. AND MOST IMPORTANT. I am not responsible for the operation of the tool, made in the footsteps of my articles.” And the last thing. Do I see errors, judging by the photographs, of the execution of this tool. Yes, I see, and a rude one. Look closely at the plate, which is the carrier for the four knives. Look closely at the FAR RIGHT HOLE in the photo.

Alas, the author of this device does not even suspect how the hole for the shaft should be made.

I inform you that the distance from the point of the hole closest to the edge of the plate to the very edge should be NOT LESS than the diameter of the hole itself. Students of mechanics will learn this truth no later than the second year of the institute. What do we see here? A thin isthmus resembling a narrow PEREKOP, making a peninsula out of the Crimea. This is a priori the place that is weak in this design. it experiences the same loads as other knives, but the “digging” there is very thin. Where it is thin, there and I would like to hope, and quite sincerely, that over these three years this isthmus has not undergone loads comparable to the yield strength of this metal, but rather the alloy from which the perforated plate is stamped.

grass trimmer. drill attachment

Materials and tools used by the author:

List of materials:. threaded rods;. a piece of pipe for a rod;. nuts;. bearings;. a reducer from an angle grinder;. plumbing parts for sewage;. clamps and more.

Step one. Preparing the gearbox To begin with, we disassemble the angle grinder, take out the gearbox with an anchor. The anchor needs to be cut off with a hacksaw for metal or an angle grinder, we knock down the remains of the anchor and get the axis. On the axis, we need to cut a thread, a long nut is screwed onto the thread. This will be the output of the gearbox, where the grass trimmer line will be placed.

The shaft on the other side will connect to the axis that the drill rotates. Since the axles will be connected at an angle, we need a hinge, it can be a cross from a small universal joint or a cross from a set of wrenches. For fastening the cross, we drill a hole, cut a thread, and so on.

Step two. Assembling the barbell Assembling the barbell, we need a piece of metal pipe, preferably with a thin wall, so that the homemade product is easy. Radial bearings must be installed in the pipe; for their installation, the author cut out rubber bands. You can also find a rubber hose of such a diameter that you can press the bearings into it. Thanks to rubber, the bearings will sit tightly in the rod, and such an approach will be able to compensate for the curvature of the shaft.

You can install the shaft, the author used two threaded rods, connecting them to each other with a nut. To get stops, we put nuts on the shaft in the right places, and as a reliable stop it would be good to weld a washer to the rod.

Step three. Assembling the homemade product, installing the gearbox on the bar, for this the author uses plumbing parts. As a result, the gearbox will be fixed at a certain angle, we connect the axles with a cross.

We put a clamp for water pipes on the bar, and to it we attach a handle for an angle grinder. That’s all, it remains to clamp the end of the axis in the drill chuck and you can test.

Step four. Tests As a working body, the author first put a metal cable, but such a “line” will quickly break, get tangled, and so on. But if you put a piece of trimmer line, the homemade product works fine. The author easily mows grass, burdocks and other vegetation. As a result, the grass trimmer turned out to be a cordless one, the author’s drill on a battery.

Over the past 1000 days, a clear picture has emerged: “Glory to the author, the craftsman, who conducts an experiment on himself to reach the yield point of the metal from which these knives are made.

This is my personal experiment. If you are unsure of your plumbing skills, please do not repeat it. AND THE MOST IMPORTANT. I am not responsible for the operation of the tool, made in the footsteps of my article. ” And the last thing. Do I see errors, judging by the photographs, of the execution of this tool. Yes, I see, and a rude one. Look closely at the plate, which is the carrier for the four knives. Look closely at the FAR RIGHT HOLE in the photo.

Alas, the author of this device does not even suspect how the hole for the shaft should be made.

Grass trimmer blade

The design of the nozzle is very simple. To make it, it was required to make only four parts: a central bushing, a washer and two petal knives (see Fig.).

I made the central bushing from a cut of a regular water pipe. To adjust its inner diameter to the diameter of the shaft, I made a through longitudinal cut on one side of the workpiece and lightly sieged it with a hammer. The bushing must sit tightly on the shaft, without backlash.

I managed to find a ready-made washer of suitable size. But, if such is not found, it is easy to cut it out with a chisel from sheet steel 34 mm thick and modify it with a file. I put the washer on the sleeve and welded it at four points. That’s enough.

I cut out the petal knives from 1 mm thick stainless steel sheet. The knives are riveted to the washer. They must be made of steel. I used M4 screws as rivets. They must be riveted so that the knives are not firmly pressed against the washer, but can rotate freely. This is a very important point. If the knives are fixed firmly, then they will most likely bend or break at the first meeting with the stem, which cannot be cut in one turn of the grass trimmer shaft.

The assembled attachment is pushed onto the grass trimmer shaft and secured with a copper cotter pin ∅3 mm. It is better to drill the hole for the cotter pin in place.

The very first trials of the grass trimmer with the new knife attachment confirmed its effectiveness. The knives easily “took” almost any grass. And during unhurried work, the electric motor practically did not overload. In a word, what you need!

However, it should not be forgotten that metal knives are a more serious danger than thin, almost weightless line. Therefore, it is advisable to mow the grass around the house when there are no people or pets nearby. And, of course, you need to constantly monitor the wear of the knives and the rivets that fasten them.

From a safety point of view, hacksaw blades should not be completely hardened.

Do-it-yourself indestructible knife for a garden grass trimmer.

The lawn on the site is not always a soft green carpet. When a friend bought a house outside the city, I was amazed at the neglect of the site. Not only did they not plant anything on the site, they did not even mow the jungle from weeds. The only thing that I could state, looking at this disgrace: the land is rested and fertile.

A previously purchased electric grass trimmer had to be put in the garage and armed with shovels and an ax. We waved vigorously all day, but only a quarter of the site was cleared. The rest was postponed until next weekend.

For the next weekend, a friend bought a three-section grass trimmer knife. Despite the rainy weather, the test was carried out

The very first impression: any serious weed trunk that fell under this knife, is given a powerful blow to the hands. After 10 minutes of work, the sharp edge of the knife became dull and a lot of burrs formed. There was no point in further ruining the grass trimmer. A friend decided to sharpen and harden the knife again in production conditions.

On the next weekend I come to visit him.

-. And how are we going to clear the thickets? You joined Greenpeace in a week and decided to save the jungle?

-Not. I made a knife of a different design!

I immediately called the design a “boomerang”) Not only is it pleasing to the eye with its appearance, but it is also made very competently! The curved shape eliminates blows when branches and trunks hit. This will extend the life of not only the sharpening of the knife, but also the grass trimmer bearings. Holes in the plane of the knives are made to increase the strength of the petals. The length of the knives is slightly longer than the “native” ones

This is done to increase the length of the cutting edge. A distance of a couple of centimeters remains to the stop of the limiter

They drove a new knife to work. The most positive impressions! No vibration, no shock. She cuts the trunks of the undergrowth like clockwork. The rest of the jungle was cleared in a couple of hours. Until the evening we still managed to walk with a walk-behind tractor.

At the request for a drawing, he only shrugged his shoulders. I drew without any calculations on a piece of cardboard in full size. Then the adjustment was made during the manufacturing process. If anyone is interested, I can, putting a knife on a Whatman paper, circle along the contour.

The construction of the “Tsar’s office” was also completed. But this will be a separate story.

Nozzles for walk-behind tractors

In addition to the above nozzles for motoblocks, there are others that you should pay attention to.

Potato weeding machines

It cannot be argued that there is an ideal weeding mechanism for potatoes that would satisfy the needs of any farmer. Therefore, in order to choose the right mechanism for weeding potatoes, it is important to know about the existing mechanisms and about the cases in which this or that mechanism or nozzle is used for it. In the video below you can learn how to weed potatoes using a walk-behind tractor.

single axle tractor with rotary cutters

a single-axle tractor is a multifunctional mechanism that, depending on the type of attachment, allows you to perform operations such as cultivation, weeding, milling, transportation of small carts, digging out root crops.

The main components are the frame, engine, transmission, work shaft and guide arms. In addition, there are various attachments that perform a specific function. Motoblocks run on an internal combustion engine, while they are two- and four-stroke.

For mechanized weeding (cultivation), a special attachment is used. a cutter. It is a series of sharp, star-shaped plates that fit over the working shaft. As they work, they rotate, grinding and pulling weeds out of the ground. The same attachment is suitable for mixing organic fertilizers with soil.

Weeding potatoes: rules, timing, weeding tools

Today, potatoes are one of the basic crops that form the basis of the human diet. It is found in almost any dish as a main or additional ingredient. Therefore, it is important to know more about the technique of its cultivation, especially about the weeding technique, without which it is impossible to get a decent harvest of potatoes.

Weeding potatoes with a trimmer

It has already been mentioned above about the efficiency and rules of weeding potatoes with a trimmer. At the same time, the grass trimmer and attachment devices are so simple that you can make your own attachments. At the same time, the lawn mower will not lose its efficiency, but on the contrary, it will be more gentle on the beds.

Is it possible to weed potatoes during flowering?

Regarding this issue, experienced agronomists and amateur gardeners were divided into two camps: some believe that potatoes should in no case be overgrown with weeds even during the flowering of potatoes, others believe that at this stage, overgrowing of potatoes with weeds will no longer harm the crop, therefore weeds you can no longer weed, but mow along with the tops when harvesting.

At the same time, everyone is unanimous in the opinion that weeding potatoes during flowering will not harm him. First of all, this will keep the beds clean until harvesting. In addition, during weeding, the soil is loosened and saturated with oxygen at the same time. Since potatoes love loose soil and oxygen, weeding potato bushes during flowering will only have a positive effect.

Milling cutter

This nozzle can be used not only for weeding, but also for loosening the earth, digging up soil with fertilizers and other purposes. it is not for nothing that this nozzle has the popular name “soil cutter”. The shape of the nozzles can be different. from discs with smooth edges to star-shaped, pin-shaped nozzles. The main principle of operation, however, is one. the tiller rotates, grinding the soil along with weeds and fertilizers. The main advantage of the nozzle is its versatility.

DIY potato weeding tools

Recently, it has been quite difficult to find quality factory tools at an inexpensive price, which forces farmers and gardeners to make weeding tools with their own hands. At the same time, the tools are metal, so it will be difficult to make them without using a welding machine and welding skills.

So, for hand weeding, homemade products like a flat cutter are very popular. The working tool is a sharpened square frame, in front of which a hedgehog-style nozzle is attached, which facilitates the movement of the tool during weeding. The finished nozzle is attached to a wooden nozzle. This product is easy to make yourself using a welding machine, as well as existing metal fragments and factory samples of tools that have become unusable.

To make a device that can do both weeding and hilling of potatoes at the same time, you can take the frame of an old bicycle, leaving one wheel on it. On the other hand, a V-shaped plow attachment should be attached to the base of the frame.

Chopper assembly

If the grass trimmer works well after assembly, then a grass trimmer is created from it.

Motor-scythe engine is attached to the board with clamps.
Fix the bar on a wooden base using clamps and a brushcutter handle.
Connect the cutting attachment to the end of the bar previously inserted into the hole in the bottom of the casing.
They start the mechanism and test it in operation.

After the actions taken, you will get an assembly, a photo of which is presented below.

If the grass trimmer used to assemble the shredder is equipped with a gasoline engine, then the motor is positioned on the base so that it is convenient to fill in fuel, start the device and adjust its operation (rpm).

Cutting attachments are equipped with knives or fishing line. it depends on the thickness of the plant stems to be chopped.

Garden Shredder From Washing Machine

An old Soviet-made washing machine with a metal body is a technique that contains almost all the necessary parts for assembling a garden shredder. You only need knives with fasteners, as well as a wire for an extension cord.

You can use an old wood saw to make a cutting attachment.

angle grinder;
pliers;
spanners;
screwdriver;
electric drill;
a hammer;
tape measure with marker.

The washing machine engine has a low power (different for different models), indicated in the instructions for household appliances or on the electric motor plate. Due to the fact that usually its value does not exceed 500 watts, with the help of the created unit it will be possible to grind only straw or grass.

A washing machine shredder is made as follows.

Cut the body of the machine in height so that it is convenient to work with the unit.
On the side at the bottom, a rectangular hole is cut out in it with an angle grinder 20 cm wide and 7 cm high, intended for ejection of ground plants.
Around the slot, a kind of casing is made of tin, which will direct the grass mass into the collection container, while preventing it from flying around the sides.
Make legs.
Attach the case to the stand.
2 holes with a diameter of 7 mm are drilled on the shaft of the electric motor. Then a threaded sleeve is placed on it, as well as holes at the end longer than 5 cm, fixing it with bolts.
An electric motor is attached under the bottom of the box using studs with nuts.
Inside the casing, the knives are fixed on the sleeve, placing them above the hole for ejecting grass or at the same level with it.
The box is attached by welding or bolts to the stand.

The result is a technique similar to the one shown in the photo below.

The start button will fit from a converted washing machine. You just need to take care to connect an extension cord of sufficient length.

The device and operation of a grass cutter from a modern washing machine are shown in the video

The main units of the garden shredder

In order to independently assemble a grass and branch shredder (shredder) at home, you must first understand the mechanism of the mechanism, as well as the principle of its operation. This will help to properly assemble the equipment and, if necessary, make changes to its design.

A home-made unit designed for chopping mowed grass and sawn branches up to several centimeters thick, has the following main structural units:

engine;
knives mounted on the working shaft;
frame (usually metal);
protective cover;
a box designed to receive cut vegetation;
launch system.

The technique itself can be made in a stationary or mobile form. To create the latter option, you will additionally need wheels, as well as a handle. To make a frame, use metal corners or ready-made frames from workbenches. Boxes for recycled vegetation are made of plastic buckets, tin, bags. The protective cover around the knives must be thick and strong enough so that it does not quickly wear out from the action of the milled vegetation.

When processing plant debris, shredded pieces can fly out of the hole through which it is fed. Therefore, the neck is covered with a lid or just a cloth, for example, a bag.

The work of the shredder is that the rotation from the motor shaft is transmitted directly to the blades or through a chain / belt drive. The vegetation chopped up by the blades enters the box. In this case, the final product is immediately ready for use.

According to the principle of operation, some homemade shredders are comparable to a meat grinder (they pull in and then grind organic matter), and others with a coffee grinder.

Grass cutter from grass trimmer

A garden shredder can be made using a gasoline or electric grass trimmer. This will cause the tool to work upside down. To create equipment designed to chop grass and thin twigs, you will need, in addition to brushcutters with cutting attachments, the following materials:

Brilliant use of the grass trimmer! Homemade Rotary CULTIVATOR For TRIMMER

a plastic or metal container with a volume of at least 50 liters;
about 1 sq. steel mesh with a small mesh size;
about 3 meters of metal tube (aluminum or steel) half an inch in diameter;
a piece of board or moisture resistant chipboard, plywood of such width that a grass trimmer fits on it;
clamps that will attach the mower to a wooden base;
self-tapping screws, bolts, nuts, washers;
wooden blocks (enough 5 by 5 cm).

To assemble a chopping mechanism from a grass trimmer, you will need to use the following tools and devices:

a screwdriver or an electric screwdriver with bits;
electric drill with a set of drills for wood and metal;
an electric jigsaw with files for cutting metal or its manual analog;
hammer;
open-end or socket wrenches;
punch;
anvil or flat iron plate.

A punch is needed so that it is convenient to drill holes with an electric drill. This tool is pointed to the point where you want to drill through the metal. Then they hit him with a hammer. The drill does not slip out of the recess obtained during the process of drilling a metal part.

Types of cutting attachments used

Homemade products, like factory units, are equipped with cutting attachments of various types:

milling and turbine (universal).

The first variety is flat blades. When rotating, they grind plant debris. If you have to recycle branches, then these blades quickly become dull. Milling knives are a cutting shaft in the form of gears from circular saws. They finely grind dry waste from branches and grass, and wet ones clog cutters. Milling-turbine cutting nozzles are able to cope with thick and not dried branches, but it is difficult to make them yourself.

At home, knives from lawn mowers or made from wood saws are often used.

It should be borne in mind that the degree of processing of plant waste directly depends on the installed cutting attachments. At the exit, they receive pieces of branches from 10 cm long or shavings, dust.

Homemade grass chopper from an angle grinder

A grass chopper from an angle grinder is a fairly simple and quickly implemented option. To implement the project, you will need to stock up on the following details and materials:

steel corners;
metal container (conventional boiling);
homemade or ready-made knives (for example, from a lawn mower);
fasteners;
sheet metal.
electric drill;
welding machine and electrodes to it;
angle grinder to cut corners;
spanners.

To assemble a shredder with your own hands on the basis of an angle grinder, capable of grinding not only grass, but also branches up to 4 cm thick, it is recommended to use a power tool with a power of over 3 kW.

The creation of a grinding unit is carried out in the following sequence:

cut the corners into pieces with an angle grinder;
a frame resembling a chair is welded from them;
weld on a shelf from a piece of sheet metal;
an angle grinder is attached to the made frame (on a stand) with clamps, placing it with the shaft to the top;
cut a hole about 10 by 10 cm on the side of the boil;
a sleeve, for example, made of tin, is attached to the slot, through which the ground plant mass will be dispensed from the container;
make a hole in the center at the bottom of the boil;
install the container on the shaft of the angle grinder and attach it with bolts or self-tapping screws to the metal frame;
put a knife or disc on an angle grinder.

As a result, you get the design shown in the photo below.

The dimensions of the corners are selected individually so that it is convenient to handle the mechanism.

It should be remembered that the frame must be stable. The safety of working with the device will depend on this.

A bucket or other container is placed under the pipe for dispensing chopped grass with branches while working with the unit so that the processed plants do not scatter.

The created device can be improved. To do this, you need a nozzle on the shaft of an angle grinder about 15 cm long with two knives: at the upper end and in the middle. The blades are separated by a mesh fixed to the wall of the casing.

Preparatory activities

A grass cutter from a brushcutter is made in a number of stages. Initially, they are prepared in a container where the grass and branches will be ground:

markings are made at the bottom (along the perimeter) for four trapezoidal holes with rounded corners;
drilled in each drawn segment of the hole with a cross section of 1 cm;
a jigsaw file is inserted into them and trapeziums are cut;
process the sections with a file or sandpaper;
a hole is drilled in the center of the bottom for the chopper shaft;
a circle is cut out of a steel mesh with dimensions along the diameter of the bottom;
with the help of small scraps of boards or blocks, the prepared mesh fragment is fixed to the bottom of the container;
legs are made of metal tubes under the container, attaching them to the tank with bolts.

Wooden pieces are fixed with self-tapping screws, twisting them from the inside of the tank into metal jumpers between the cut-out trapezoids. In this way, the net is securely attached to the bottom of the container.

bend the tubes in a vice or with a pipe bender in the form of the letter “P”;
the ends of future supports are flattened with a hammer;
2 holes are drilled in them on each side (6.5 or 8.5 mm in cross section);
fit the workpieces to the bottom of the container and mark the points of the bolted joints;
drilled at the hole mark;
using bolts with washers and nuts, attach to the footrest cover.

After preparing the casing, in order to reduce the dimensions of the created mechanism, perform the following operations:

disassemble the grass trimmer by disconnecting the motor, bar and cutting attachment from each other;
a fragment of about 20-40 centimeters in length is cut off from the bar with a cable;
collect a brushcutter;
check the performance of equipment.

Varieties of engines for assembling homemade products

Electric and gasoline engines removed from unused equipment are used as a drive for homemade products. Each of these two options has its own advantages and disadvantages. Models with an internal combustion engine are more convenient in that their operation does not require the presence of a power supply network nearby. But in general, they are more expensive and have a more complex structure than their counterparts equipped with an electric motor. Therefore, it is easier to make electrical equipment, in addition more compact.

The maximum thickness of the cut branches that the chipper can grind depends on the power of the electric motor installed on it and the characteristics of the knives.

Models with a motor up to 1.5 kW are capable of grinding sticks up to 20 mm in diameter. They are designed for low intensity work.
If an electric motor from 3 to 4 kW is installed, then such units can chop branches already up to 40 mm thick.
powerful electric motors (over 4 kW) are used to make a wood shredder with a diameter of 7-15 cm.

The drive of the latter category is equipped with equipment if it is necessary to constantly perform large volumes of work associated with the processing of waste of various thicknesses.

To create a homemade shredder, you can use electric motors from an angle grinder, washing machine, grass trimmer. They must be adapted to work from a stationary network with a voltage of 220 V. In order to grind material as thick as possible at home, it is recommended to equip the shredder with an electric motor for 1500 rpm with a power of about 3.5 kW. This parameter for internal combustion engines corresponds to 5-6 horsepower.
