Installing the coulter in the holder, you need to fix it through a particular hole, using the cotter pin. The choice of hole depends on the desired depth of cultivation. If you want to set the minimum depth, you should install the coulter to the holder through the lower hole.
Stopper (coulter) 3-hole. an attachment for a power tiller with which the depth of the tiller is controlled during cultivation of the land, the speed of the power tiller is regulated by the coulter.
the coulter is placed at the back of the cultivator. By pushing it into the ground, the operator makes the cultivator work in one place. If the coulter is raised, the tines will pull the cultivator forward. When working with a cultivator, depending on the type of soil, it is important to manipulate this element correctly, slowing down and speeding up the machine.
- to increase the depth the coulter must be lowered down and attached to the ear through the upper holes;
- in order to reduce the depth the coulter should be lifted up and attached to the bracket through the below-mentioned holes.
when the coulter is placed in the bracket, it must be hooked in one hole or the other using a cotter pin. The choice of hole depends on the depth you want to work the ground. If you want to set a minimum depth, the coulter should be mounted to the holder through the lower hole.
When installing the coulter to the carrier, one must secure it through a hole or other, using the cotter pin. The choice of hole depends on the depth you want to work the ground. If you want to set the minimum depth, you should install the coulter on the holder through the lower hole.
Beginning farmers often encounter problems with a cultivator that are caused by improper use. It is not uncommon for a power tiller to be buried in the ground and cannot be manipulated by the operator. To solve this problem, first of all, you should deal with the causes of its occurrence.
If the cultivator is buried during plowing, it is caused by several reasons.
- this is often due to the configuration of the machines. often than not, mini-cultivators are equipped with four cutters. Provided the manufacturer uses quality metal to make them, they will have a lot of weight. Because of this, the working elements will pull the cultivator into the soil;
- sharp cutter blades. if the cutting elements are sharpened, the cultivator will not move forward, but on the contrary, it will bury itself in the ground;
- High load on the engine. in such a case, the engine will create strong vibrations, which will upset the balance. Because of this, the cultivator will become deep into the ground in place, instead of moving across the vegetable garden;
- The second most common cause is that the cultivator does not switch to second speed at the right time. This should not be done when plowing loose soil and in conditions of high moisture;
- The cultivator often goes into a trench because the burr is not fitted correctly. If the angle for attaching them to the hitch is greater than required by the application manual, it will also cause the machine to dig in.
Very often the technique is buried in the ground because of too zealous pushing on the part of the operator. The operator must remember that he should only push the implement slightly in the right direction. If too much force is applied, the balance of the cultivator is upset and the machine digs into the ground at all times.
If the cultivator is buried in the ground, the operator should take a number of measures.
- Dismantle the outermost cutting blades from the milling machines. this will reduce the weight of the equipment. Another way to improve the balance of the machine is to put any small weight at the back of the machine. It is very important to fix the counterweight firmly, otherwise it will fall under the influence of engine vibration;
- Switch the machine to reverse in order to pull it quickly out of the ground. If it is not provided in the design, you will have to pull the machine out of the ground by yourself;
- The operator must adjust the position of the blades during work. Their cutting blades must always point straight in the direction of the movement of the equipment.
In order to avoid burying the cultivator, it is necessary to carefully inspect the transmission before working. This mechanism must be in good working order. A cultivator may not be operated if the machine is operated at random speed.
If the farmer noticed this breakdown, it will be necessary to inspect the transmission gears. Self-shifting is an indication that the gears of other implements are jammed. To fix the breakage, you will need to adjust the distance between the channels and the transmission gears.
To eliminate the risk of the cultivator sinking into the ground, the farmer must follow a list of certain rules.
- Do not rush to work the soil immediately after precipitation. The machine will sink too quickly into excessively soft, wet soil. In addition, high soil moisture will lead to the formation of rust on cutters and other metal elements of the cultivator;
- adjust the coulter correctly before each use of the cultivator;
- Set the gas regulator on the implement to the maximum permissible value and always check the gear shifting mechanism
- Till the soil at least twice. During the first cultivation the coulter should be set in the minimum depth position. The second cultivation should be performed with the coulter set to the desired depth of the farmer.
When using a cultivator, it is necessary to remember that a thorough check and adjustment of the equipment are the main ways to help prevent the equipment from getting buried.
In order to exclude the burying of the cultivator and a number of other common problems, the owner of the equipment should perform a number of actions on its preparation and adjustment.
- First, the cultivator should be installed on a thick board, and remove the factory wheels from it. Instead, it is necessary to fix one set of cutters on the left and right side each. One set of burrs includes 8 cutting blades. this number of elements gives the best result in ground cultivation;
- Pay attention to the position of the blades when installing them. They should only point forward. The working part of each blade must not be sharp. The front of the machine is in the neutral position for the first pass. In addition, the sharp blade will cut the stalks of the weeds, instead of winding them up and pulling them out together with the roots;
- Next, it will be necessary to install a clevis on the machine, which is necessary for mounting the coulter;
- The coulter bar is a slat bar with holes drilled in it. This is necessary for the fine adjustment of the tines when cultivating a field;
- To fix the coulter, it must be installed in the earring and secured with cotter pins and bushings. For this purpose a second hole is selected. The working depth is measured from the bottom of the coulter. This gives a cultivation depth of 20 cm. This is quite sufficient for good tillage and the elimination of large weeds;
- In order to increase the depth of cultivation, the coulter must be lowered down, and attached to the shackle through its upper hole element;
- In order to reduce the plowing depth, the coulter should be lifted up, and secured to the clevis through its lower hole.
After setting and adjusting the equipment, the cultivator can be operated. In order to accurately determine the depth of plowing, it is necessary to make a control run of the technique over the plot.
At this time it is necessary to pay attention to the cultivator’s work. If his engine vibrates and smokes strongly, it means that the technique succumbs to excessive loads.
In this case you will need to set the coulter to a shallower depth and check the operation of the cultivator again.
After the first working depth is reached, the coulter should be set to a deeper working depth. This arrangement allows you to work the area well and not to damage the working mechanism of the cultivator.
Cultivation is the treatment of the land without the plough. If during plowing soil is turned over in layers with a tiller, during cultivation only loosening of the soil to a certain depth occurs, thereby fertile soil layer remains in place, which ensures a rich harvest from the land.
Preservation of the formed fertile layer is one of the main advantages of tillage with milling machines, but there is also one disadvantage. If land is prepared for winter with tillers instead of a plough, the ground will be reconsolidated in spring after the snow has melted and you will need to start the tractor all over again to cultivate your land.
Cultivation with a power tiller after winter is difficult, especially if you have not previously plowed the ground. The soil is compacted, and the load on a single-axle tractor increases several times.
It is worth mentioning the fact that during cultivation the tillers can have different depths, so the quality of soil processing may be unsatisfactory.
To achieve the maximum effect from the cultivation of the land the following method of cultivation is used.
If after the winter period first plow the area to a depth of at least 10 cm, thereby loosening the top compacted layer of soil, you can achieve the most positive result from the subsequent cultivation with the burial of the tillers at 15-25 cm.
Let’s move on to a step-by-step study of how to do the job of cultivating your plot of land with a power tiller.
To obtain high quality tillage with the tillers it is necessary to choose the right speed mode. Usually there are two gears available for the forward movement of the power tiller:
In contrast to plowing, when cultivating the soil, the single-axle tractor must operate at higher speed, so in this case you must choose a higher gear to increase the speed of rotation of the cutters.
The choice of a higher gear reduces the load on the engine of the power tiller, and with an increased number of rotational speed of the tillers the quality of loosening the soil is significantly improved.
After the first run, check the working depth. If the depth is satisfactory then it is possible to continue with the cultivation of the plot. Passing the second strip should be done so that the cutters go along the mowing line left by the coulter, because between the cutters of the power tiller there is an uncultivated area of soil.
When working on cultivating the vegetable garden, do not push the steering wheel down, do not push the single axle tractor forward. all this can cause the single axle tractor to start digging into the ground.
Choosing the Right Tiller For Your Compact Tractor
In photo 10 you can see that the single axle tractor has stopped moving forward, the cutters have gone very deep into the soil layer. In simple terms. the single axle tractor is buried in the ground! Why does this happen?? Here are the main reasons why a single axle tractor gets buried, as well as ways to eliminate them.
The soil is too wet and is blocking the blades, you need to wait until the soil dries out.
Coulter is pushed too deep into the soil, the coulter needs to be readjusted.
Lack of rpm, you must set the throttle control to maximum and check the speed (select a higher gear).
The soil on the plot is heavily compacted, so it is necessary to perform cultivation of the plot in two times:
- Primary tillage at minimum coulter depth.
- Final tillage is performed when the coulter is deepened to the desired depth.
Incorrectly installed tillers of the motoblock, check the correct installation of the cutters.
These are the most common reasons why tillers of a power tiller go too deep in the ground and a single-axle tractor stands.
Details and nuances
It is important to understand that the coulter installed on power tillers and power tillers is not capable of doing the same work as similar devices on “big” tractors. There is no point in waiting for them:
There are only two functions available: Adjusting the depth and pace of cultivation and making an extra point of reference when storing. Therefore, there may be different names for this part:
Spur (in the lines of a number of European companies).
Coulters for some models of power tillers (cultivators) can have only 2 regulating positions. There are even machines where the penetration of the point is not adjustable. Example. Caiman Eco Max 50S C2 coulter. But it is possible to change the speed of the cultivator by manipulating the handles. Please note: On larger cultivators and power tillers, the coulter must be able to move freely left and right.
The correct work organization when using the coulter is as follows:
Waiting for the ground to be loosened around the cutters;
When plowing virgin land is planned, the depth of cutters is usually made relatively shallow in order to assess the result. Only after a test portion of the plot is it possible to tell whether the depth needs to be changed or not. If the engine starts to run up when the working depth is reduced, you have to deepen the coulter a little more. The regulator on Neva-type power tillers should first be set in the middle position. Then, based on the density of the soil and how easy it is to traverse, carry out the final adjustment.
About what coulters for a motor-block and how to install them correctly, see the video below.
Design features of Class coulters
Specialists most often recommend for installation with your own hands the individual reproduction Class coulters. Their specifications are exactly as described above. Unvarying placement depth of seed is achieved by the special design of the arms and depth guidance wheels. Since the joints are supported by springs at the most heavily loaded point, it is possible to adjust the pressure on the coulter surface. A well-designed safety spring prevents damage to the main coulter parts even when hitting various kinds of obstacles.
Preparation and mounting of coulters to a single axle tractor
A set of cutters can consist of 16, 24 or 32 cutting plates, it depends on the soil of your area, and on the size of the cultivated area. In small areas it is not desirable to use a router set with more than 16 blades. Because a blade set like the one in photo 2 (8 blades on one side and the same number of blades on the other side) is the optimal solution, it reduces the load on the tiller engine and you do less work on the ground.
Picture 1 Preparation of the cutters is to assemble the sets correctly. Picture 1 shows the left side cutter set with eight cutting inserts (A and B) and the base plate.
Photo 2 shows an example of how to attach the blades to the base in which order. Note that the cutting part of the inserts must have the same direction as shown by the arrows in photo 2.
And what is also important is that the sharpening of the cutting part of the cutters is categorically not recommended. If you sharpen the cutters, the whole point of cultivation is lost.
Why do you ask? When cultivating soil with a power tiller with sharply sharpened cutters, the root system of weeds will not be lifted to the surface, but simply the following will happen The root system is cut by the sharp cutter and remains in the soil, so the weeds will successfully germinate in the place where you cultivated the soil with the cutters.
The next reason not to sharpen the tillers is the load on the engine of the power tiller and the depth of tillage.
With sharpened cutters single-axle tractor simply will not move forward, and will constantly, buried in the ground, since cutters after sharpening lose the ability to capture the soil and just cut it.
Therefore, cutters will be deeply buried in the soil (more than 25 cm) and single-axle tractor will lose the ability to move the site.
After you finish assembling the burr set, you need to be careful when installing them on the single axle tractor.
The direction of the cutting edge of the shins should point in the direction of travel of the power tiller. Do not confuse left hand drill with right hand drill.
Adjust coulter depth. When positioning the coulter in the coulter arm, it must be locked in one hole or the other using a cotter pin. The choice of hole depends on the depth you want to work the ground. If you want to set the minimum depth, the coulter should be placed on the support wheel through the bottom hole.
To recreate the machine in this position, you must place the wheel supports under the left wheel of the power tiller at the same height as the plowing depth. The ploughing depth is set with the depth adjustment wheel. The deeper the support wheel is lowered, the shallower the ploughing depth and vice versa.
The cultivator should move smoothly and evenly. If it digs into the ground, adjust the wheels or swap cutters. After using the machine, wipe all of its metal parts with a cloth. If necessary, rinse the cutters, followed by wiping them dry.
