What is a tiller coulter??
coulter depth adjustment. When installing the coulter in the holder, you must secure it through one or the other hole, using a cotter pin. the choice of hole depends on the depth you want to work. If you want to set a shallow depth the coulter should be placed on the carrier through the bottom hole.
- To increase the depth the coulter is lowered down and attached to the clevis via the upper holes;
- To reduce the depth, the coulter should be lifted up and attached to the clevis through the below-mentioned holes.
Design features of the Class coulters
Professionals most often recommend that you install with your own hands individual reproduction coulters Class. Their characteristics are exactly as described above. Unvarying placement depth of the seed is achieved by a special arrangement of levers and support wheels. Since the pivot points are supported by springs at the most tensioned points, the pressure on the coulter surface can be readjusted. the basic parts of the coulter are not damaged, even when encountering obstacles.
First of all, the bracket must be fitted. Already the working part has to be fitted. It is attached by means of cotter pins and bushes. Important: Fasteners must be inserted into the second hole from below. This gives the possibility to adjust the coulter penetration to an optimum depth for the complete cultivation of the soil.
Sometimes the standard plunging (20 cm) is not sufficient. In order to set the coulter to a deeper penetration, it is lowered and affixed to a clevis through the upper holes. On the contrary, if you need to work only the uppermost layer of soil, before using the tool, it is attached through the bottom hole. Specialists recommend that you first arrange a test run of the power tiller. It is the only way to find out if everything was done correctly.
Details and nuances
It is important to understand that the coulter installed on motor blocks and power tillers is not capable of doing the same job as similar devices on “big” tractors. There is no point in waiting for them:
There are only two functions available: Adjusting the depth and working pace of the ground, and an additional reference point for storage. That’s why 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 may have only 2 adjustments. There are even some that do not have the depth of the sharp end adjustable. Example. Caiman Eco Max 50S C2 brand coulter. But it is possible to change the speed of the cultivator by manipulating the handles. Note: On powerful cultivators and power tillers, the coulter must be able to move freely to the right and left.
The correct organization of work with the coulter is as follows
Waiting for the soil to be loosened around the cutters;
When plowing virgin land is planned, the depth of the tillers is usually made relatively shallow to assess the result. Only after processing a test portion of the plot, you can say whether you need to change the depth or not. If the engine starts to run up when the working depth is reduced, you have to deepen the coulter a bit more. For “Neva” type power tillers, the regulator is set in the middle position to begin with. Then, using the density of the soil and how easy it is to pass, make final adjustments.
To learn what coulters for a power tiller are and how to install them, watch the video below.
Cultivating a site with a power tiller
In order to obtain a high quality of tillage with cutters it is necessary to choose the right speed mode. Usually there are two gears available to move the power tiller forward:
Unlike plowing, when cultivating the soil the single-axle tractor must work at an increased speed, so in this case it is necessary to choose an increased gear to increase the rotation speed of the cutters.
The choice of a higher gear reduces the engine load on the power tiller, and with a higher rotational speed of the tillers the quality of loosening the soil is considerably improved.
After passing the first strip check the working depth. If the depth is satisfactory, you can continue cultivating the land. Passing of the second lane must be done so that the cutters follow the line left by the coulter bar, because an uncultivated area of soil remains between the tillers of the power tiller.
When working to cultivate the vegetable garden, you should not push the steering wheel down or push the single-axle tractor forward. all this can cause the single-axle tractor to dig into the ground.
Cultivating a site with a power tiller with your own hands: detailed photo instructions
Cultivation is the treatment of land plot by no-till method. If during plowing the land with a power tiller the soil is turned over in layers, in the case of cultivation the soil is only loosened to a certain depth, thereby fertile soil layer remains in place, which ensures a rich harvest from the land.
Preservation of the formed fertile layer. this is one of the main advantages of tillage with milling machines, but there is one drawback. If the land is prepared for the winter period with the help of milling machines instead of the plough the ground will be hardened again in spring after the snow melt and you will have to restart the tractor and cultivate your land.
Cultivation with a power tiller after winter is difficult, especially if the site had not previously been tilled. The ground is compacted and the load on the single axle tractor increases several times.
It is worth noting that during the cultivation of ridges may have different value plugging, so the quality of cultivation may be unsatisfactory.
To achieve the maximum effect from land cultivation the following method of soil cultivation is used.
If after the winter period firstly to plow the area to a depth of at least 10 cm, loosening the top compacted layer of soil, you can achieve maximum positive results from the following cultivation with a deepening of tillers by 15-25 cm.
Let’s proceed to the step by step study of how to perform the work on cultivation of our land plot with the help of a power tiller.
Cultivating a plot with a power tiller
Select the right speed to achieve good tillage quality with milling cutters. Usually there are two gears for forward motion of the power tiller:
In contrast to plowing, when cultivating the soil, the single-axle tractor must operate at an increased speed, so in this case it is necessary to select a higher gear to increase the rotation speed of the cutters.
The choice of a higher gear reduces the load on the engine of the power tiller, and the increase of the rotational speed of the tillers considerably increases the quality of loosening the soil.
After the first pass we check the depth of cultivation. If the depth is satisfactory, you can continue cultivating the site. Till the second working pass must be done in such a way that the tines follow the line left by the coulter as there is uncultivated soil between the tines of the power tiller.
When working on cultivating the vegetable garden you should not press the steering wheel down, you should not push the single axle tractor forward. all this can cause the single axle tractor to start digging into the ground.
Reasons for the strong downgrowth of the tiller
In Picture 10 you can see that the single axle tractor has stopped moving forward, the cutters are too deep in the ground. Simply put. the single-axle tractor is buried in the ground! Why it can happen? Here are the main reasons why a single-axle tractor digs in and what to do about it.
The soil on the field is very wet and clogs the blades, you must wait until the soil dries out.
Coulter is too deep in the soil, coulter adjustment necessary.
Inadequate RPM, set the throttle control to maximum and check the ground speed (select a higher gear on the tiller).
The soil is too compacted, so cultivate the area several times:
- Till the first pass of the soil at minimum coulter depth.
- Tillage is complete when the coulter is lowered to the required depth.
Incorrectly installed tillers on the power tiller, check if the tillers are installed correctly.
These are the most common reasons that the tillers of a power tiller go deep into the ground and the single-axle tractor stands.
Cultivating a site with a power tiller
To get good tillage quality with the tillers it is necessary to choose the right speed. Usually there are two gears available for the motoblock’s forward motion:
Unlike ploughing, when cultivating the soil the single-axle tractor must work at higher speed, so in this case you must select a higher gear to increase the speed of the tillers.
The choice of a higher gear reduces the load on the engine of the power tiller, and with an increase in the rotational speed of the tillers the quality of loosening the soil is significantly improved.
After passing the first strip, check the working depth. If the depth is satisfactory, you can continue cultivating the site. The passage of the second strip must be done so that the cutters follow the line left by the coulter, because between the cutters of the motobloc remains an uncultivated area of soil.
It is worth adhering to the following rules:
- Do not put your power tool into operation until you are completely familiar with the instruction manual supplied with the machine;
- Children are not allowed to use the device, as well as those who are not experienced with the device;
- During plowing, it is important to eliminate the proximity of any animals or other people;
- The work must be carried out in closed clothing with long sleeves and closed shoes without dangling elements or in a special outfit; it is better to choose high shoes, for example boots or “bibs”, which toe is covered with a metal plate; do not forget about gloves, especially in the case of cultivating difficult soils, and protective glasses;
How much does it cost to plow a hectare of land with a power tiller??
for land plowing in the Moscow region
|Plowing with a snow thrower (coarse fraction)||hundredths of a hectare||1800|
|Tillage with a tractor (coarse fraction)||hundredweight||4000|
|Plowing virgin land with a power tiller||100||2500|
Multifunctional power tiller can do a wide range of works in the field, country house and vegetable garden. In order to quickly and accurately conduct the processing of arable land and virgin lands, along with the device using different types of attachments.
