Assembling a rotary mower for a power tiller

How to make a self-made mower on a single axle tractor

There are several modifications of mowers for the “Neva”. The most popular are produced by Kaluga plant of special equipment “Kalibr”. “Zarya” and SPb “Red October”. KP-05 and KP 1,1. You should buy the mower that meets all the needs of a particular farm. By the type of mowing the grass can be distinguished:

  • The grass is cut and folded into separate shafts. This one is convenient to stack.
  • Mulch the grass, they shred the vegetation and the front lawn will always be in order.

Due to its compact size, any mower for the “Neva” power tiller can easily pass between the greenhouses, seedbeds, fruit bushes and trees.

Rotary mower “Zarya”

By design, mowers for power tillers are divided into segment and rotary. Rotary models are easier to maintain, as their design is very basic. Rotary mowers for “Neva” consist of one or more rotating discs with moving blades. When working under the influence of centrifugal force, the blades cut the grass and fold it to one or two sides. The segmented design is more complex. The working tines are “fingers” that are clamped between two metal bars. One tine is movable and makes oscillating movements to the left and right during operation. The second Honor remains stationary. The grass gets caught between the tines as the tiller moves and is cut. The segment mower is more difficult to maintain and repair.

Design and operation of haymowers

For dense or thick grass, use a haymaker, which is part of the attachment for power tillers. The choice of mower depends on the following factors:

  • terrain, including its topography;
  • the nature of the grass;
  • financial possibilities;
  • The features of a power tiller and its characteristics;
  • the power of the technique.

Important! The mower requires a powerful single-axle tractor that can give performance for the attachment. Most machines on the market have their own mower from the manufacturer. Any variants of mowers, including homemade ones, can be installed on some power tillers, for example on Neva.

Haymowers are used for mowing grass and removing weeds. A common device includes the mowing mechanism, which depends on the type of mower, the adapter, if necessary, coupling, and fasteners. It is worth considering that there must be a supply of oil to the torque arms.

In this video, consider what kind of mower is best to choose on a single-axle tractor:

single axle tractor with hay mower

So, as a result of a long struggle to find a compromise, it was purchased:

There have already been reports on the motor-block, I will not repeat them. The engine is great, the build quality of everything else is soviet. In particular after 5 minutes of work the bolt that fixes the pulley on the engine shaft blew out with a hiss. It’s a good thing there was a shield. And after 10 minutes of work was lost the knob from the shifter, stupidly unscrewed in spite of found traces of glue But I found it Then another rubber came off the right handle well and so on. In general, it is necessary to glue and tighten. The most important claim. the bolt that attaches the steering wheel to the tiller, according to the designers’ idea, should provide easy repositioning it on the side to go sideways from the tiller. The most important claim is that the bolt that attaches the handlebar to the bike body, and the handlebar itself, is supposed to be easy to move.е. just pressed down. It needs to be tightened all the time. I’m thinking of re-cutting the thread on the bolt to pull it through the hub and tighten it with the nut on the bottom. Of course, it will be harder to move the rudder, but it’s not a good idea to keep tightening it all the time.

Now for the mower. Immediately I discovered that the shaft on which is placed the tensioner is not parallel to the main structure, as a result, after installing the tensioner it turns out that the roller distorts the trajectory of the belt. I fixed it by bending the tensioner part where the roller is installed. Let’s go the first belt was killed about 15 minutes The worst thing is that even a little bit of belt loosening because of its overheating leads to the fact that it’s already impossible to use it, because its tensioning is made by tensioning roller or by changing the mower itself by one “hole” in the console. As a result, the belt is stretched and the tensioner is not enough, and shifting the mower leads to the fact that even with the tensioner lever lowered the belt is still stretched, and to start the engine with the “connected” load I did not want to try something, in my opinion it is wrong. Change the belt, try number 2 It drives like a tank, cuts everything and everything, but if the grass is dense or decayed, it’s better to mow in small squares, t.к. on the mower’s frame there is a whole pile of tangled grass, which firstly hinders the knives from turning and secondly it rolls and crushes the grass on the side of the swath. I’ve got used to it this way. I make cuts, like “glades” every 5-7 meters, then I reverse and mow perpendicular to these cuts to throw in what has been collected on the frame. As a result, with such an approach, with very uneasy bumpy ground, dense grass and in some places already fallen down for 2 hours I manage to mow about 6 acres, with pauses on belt cooling (it was the last, and to a town 150 km.) and scattering of already cut grass.

Conclusion: I am generally satisfied, despite the aforementioned drawbacks. If I had mowed two weeks earlier, it would have been a lot easier.

How the rotary mower works

The rotary mower is started by the transmission of the power tiller and the movement of the wheels. A rotary mower is built with a support wheel and one or more discs attached to the metal frame. When the support wheel starts moving, the mowing unit also drives the cutters, which take care of the mowing.

Different models have from one to three cutting units on the metal frame. Different attachment methods are available, but the biggest advantage of having more discs is that it increases the output of the machine as a whole.

A rotary mower, fitted with two or three blades, is powered by a tractor or tiller, and covers quite a bit of ground. The presence of several cutting devices also has a positive effect on the speed of agrotechnical processing.

Machine characteristics are formed by several basic indicators:

  • the cutting height of the vegetation;
  • mowing capacity (this is calculated based on the area of mowed land during the mowing season)
  • the rotation speed of the cutting unit.

How the rotary mower works

The mower is put into work by the transmission of the power tiller, and also by the movement of the wheels of these units. The rotary mower is designed with a support wheel and one or more discs attached to a metal frame. As the ground wheel starts to move, the cutting units are set in motion and the mowing begins.

Different models offer from one to three additional cutting devices on the metal frame. They can be attached in various ways, but the main advantage of increasing their number is to increase the productivity of the machine as a whole.

The rotary mower, equipped with two or three knives, is powered by a tractor or tiller, and quite large areas of agricultural land are cultivated. The availability of several cutting devices also has a positive effect on the speed of agro-technical processing.

The characteristics of the machine are formed by several basic indicators:

  • the cutting height of the vegetation
  • productivity (this indicator is based on the area of cultivated land for the time of work);
  • the rotation speed of the cutting unit.

The rotary mower’s field of application

A mechanized farmer works faster and more productively and is able to perform the whole range of agricultural activities in time, whether it’s mowing perennial grass for livestock or harvesting wheat. With the right steel helpers you don’t have to worry about disruption of the forage harvest or the spring crop before the rainy season arrives. Rotary mowers are great for:

At the same time, this agro-technical device helps achieve the following important factors:

  • Obtaining an economic solution to the task at hand with the highest possible productivity;
  • A wear-resistant machine that is lightweight, easy to operate and maneuver;
  • Achieving high-quality mowed hay and grass that does not get damaged by the root system while the machine is in operation.

Rotary mower Zarya

It is a common alternative to the Zarya model, that can be successfully used with other power tillers. Structurally distinguished by the presence of 2 independent rotating blades, fixed to the frame. Thus the manufacturer has managed to create a solution, more convenient in some ways than the original lawnmower for the power tiller Neva. Unfortunately, because of the wide frame and 2 knives the unit is sensitive to work on rough terrain.

This mower has its advantages and disadvantages

Technical Specifications

By the principle of operation this mower for the motor-block Neva is not mounted, but trailed. Its basic parameters are similar to the standard model:

The mower requires certain rules to be observed during its operation. Check all connections before starting work: retighten any loose connections. It is forbidden to stand in the cutting area, directly in front of the mower. it can be dangerous and cause injuries. If any unusual noise or knocking noises are heard, stop working immediately.

All adjustments and repairs are performed with the equipment turned off. Every 2 hours check the tension of the belt in the drive of the mower, if it is loose, a tightening (replacement) is performed. It is not recommended to exceed the speed limit of 4 km/h. Stones and branches can be dangerous if they fly hard from under the mower blade.

Important! Clean every 12 hours and lubricate all moving parts and bearings with grease as specified in the instruction manual to keep the machine in good working order.

Design and operating principle of haymowers

For dense or thick grass use a haymower as part of the implement attachment for power tillers. The choice of mower depends on the following factors:

  • terrain, including its topography;
  • the nature of the grass;
  • financial capacity;
  • features of a power tiller and its characteristics;
  • machine power.

Important! You need a powerful single-axle tractor to operate the mower, which can give performance for the attachment. Most machines on the market have their own mower from the manufacturer. On the part of power tillers, for example, Neva, you can install any variants of mowers, including homemade.

Mowers are used for mowing grass and pulling weeds. A conventional device includes a mowing mechanism, which depends on the type of mower, an adapter if necessary, a hitch, and fasteners. The oil flow to the mowing cylinders is important.

In this video, let’s look at which mower is best for a single-axle tractor:

The advantages of a rotary mower

The main advantage of the rotary mower is the damping device installed on this unit. It reliably protects the cutting units from any obstacles encountered in the course of work.

Another advantage of this type of mower is that it mows the grass with the prospect of laying it either in a swath or in swaths on those areas of farmland where the angle of steepness is up to 20 degrees. Compared to their segmented counterparts, the flail mower is also easier and safer to operate.

Correct choice of equipment for this or that agrotechnical measure is a significant saving, and not only of time but also of energy costs. In any case, the width of the mower should be chosen according to the amount of work to be done, the area to be mowed, and the specific type of mowing.

That’s why the main task of a buyer is to choose a model that best suits the power of the machine, on which it will be installed.

How to make a mower for a power tiller with your own hands?

It often happens that for some reason the manufacturer does not have a special mower on sale, specifically for this model, or that it does not suit by its characteristics. In this case, it is not difficult to work on a homemade version. Full production on the basis of your farm will be demonstrated on the example of segmented variation.

Among the spare parts, you should first take a rectangular tube 5×1,5 with a length of 120 cm. An ordinary piece of an old grasshopper will also do. On the tube is drilled about 12 holes of each centimeter at equal distances, as shown in the drawings.

Prepare a frame of welded angles and pipes, cover it with plywood and attach the wheels. The belt is made of rubber in a ring shape. It is convenient to fasten it with duralumin plates. Also on the frame welded on clamps to install the cutting strip. For the latter, a strip with metal blades is attached to the prepared pipe with holes, prepared in advance.

Platform mower

This drawing shows a variant of platform mower, effectively used in summer for mowing grass and weeds, and as a snowblower in winter. For removing snow masses, special star-shaped nozzles are mounted on the equipment, and in the summer. knives. This modification resembles a rotary mower, but is difficult to carry out. This equipment allows you to cut the tough grass and remove snow and ice.

The design of this equipment, created with their own hands, is a pair of cylinders connected by hooks to the frame and conveyor belt. The chassis is made from a corner or any other metal that you can find in the workshop. On the chassis set the wheels, which can be taken from an unnecessary baby carriage, and a thick plywood sheet, although ideally it is better to use metal. Frame dimensions can be different, but the best would be 800×400 mm.

The main assembly consists of two cylinders (5), belt (3), frame (10, 16, 17, 18, 20), brackets (19), corner hooks (4).

The operating cylinders can be made from large cans, from which you must cut out the bottom and the lid, and in their place put two rounds of wood. Instead of cans you can use a thin sheet of metal and make it 4 disks with an outer diameter of 200 mm and 4 with an inner diameter of 170 mm. Use bolts to connect the small discs to the large discs in pairs. To these structures from disks attach four blades each.

The frame to be assembled with your own hands. The equipment consists of an upper crosspiece (10) and a metal strip with corners and sleeves (16). For the crossbar you can take a metal angle of 35×35 mm. The cylinders are attached to each other with a strap, for which you drill a 13 mm wide slit in the corner. For the same purpose the bottom hub of the driving drum is movably fastened to the bar (15), and tensioning brackets (20) are installed on the upper axes of the cylinders. To the ends of the crossbar pull the angle bars (20) by means of screws M5x65 mm. The belt for the drums is easier to make from a rubber strip, the ends of which are connected by means of a dural plate 2 mm thick.

Next, connect the mower to the power takeoff shaft of the power tiller. You can see how the mower wagon works in the following video.

Homemade mower wagon with your own hands

With a self-propelled mower, you can easily get rid of grass that has a wide stem. Let’s consider the peculiarities of making a machine.

Materials and tools

To assemble the haymaker you will need:

  • Frame made of metal corners;
  • 4 wheels;
  • Metal sheet or plywood (size 80x40cm);
  • 2 tin cans;
  • 8 metal discs;
  • 4 blades;
  • hub;
  • drum;
  • bolts;
  • conveyor belt.

Did you know? The wider and larger the wheels on the mower, the less they damage the lawn and leave no trace behind.

With the listed materials available, you can begin assembling the device using a standard set of tools.

Do you know what to do?

We suggest reading the instructions for assembling the mower:

  • Place the metal plate on the frame.
  • Put two tins without lids and bottoms on the frame. Instead of the bottom, install metal discs, the diameter of the outer. 20 cm, the inner. 17 cm.
  • Join the discs together in pairs: screw them together with bolts.
  • Attach the blades to the discs so that the distance between them is the same, allowing them to rotate freely.
  • Insert the bushing into the drum part, fasten it firmly to the frame.
  • Put a plate made of steel corners on the frame.
  • Perform the connection of the drums. You’ll need a conveyor belt for this.
  • Attach the lower pulley sleeve and attach the brackets to the lower pulley.

As a final step, make sure that the blade is protected and the machine can be mounted on a single axle tractor.

Attaching the mower properly to the single axle tractor

The newly purchased product must be properly installed on the machine to provide the desired performance and quality of execution. Let’s look at a sample assembly and installation procedure using the rotary version as an example:

  • Check the delivery set (the set may differ from model to model, but as a rule, it is the drive belt, frame, socket, fasteners, rotor cover, hydraulic hose, support skids, hydraulic cylinder, drive belt tensioning system, rotors with blades, spares);

If the system is correctly installed, mount the frame to the mounts so that the frame and vertical plane are at 45 degrees, with the slotted parts facing up;

How to impregnate plywood for moisture resistance

Put the rotors on the frame so that the blades are positioned underneath. It is important that they are fully seated on the spline;

Attach the rotor cover to the same slot;

Fix it with cotter pins and nuts;

Let’s mount the tensioning system by taking out the cotter pin and unscrew the lock nut on the pulley. Next step is to carefully knock out the pulley so that the key is not lost. If the system is installed correctly its handle will point upward and be secured with the bolts from the spare parts kit;

Then fix the skids to the frame with bolts from the spare parts kit so that their concave part faces inward;

Fit the frame rings so they are on the outside of the frame of the power harvester. After that finally connect to the second mower;

We put the drive belt on the pulley in the direction of travel. It’s important that the single-axle tractor and the mower remain aligned;

Mounting hydraulic cylinder-hose system (if the tractor is equipped with one).
