How to use a Rotary Tiller?

When we use a rotary tiller, we first need to know what is a rotary tiller.

A rotary tiller is a tilling machine that is matched with the tractor to complete tilling and harrowing operations. Because of its strong soil crushing ability and flat surface after plowing, it has been widely used; at the same time, it can cut the root stubble buried below the surface, which is convenient for the operation of the planter and provides a good seedbed for later planting.

According to the configuration of the rotary tiller shaft, it is divided into three types: horizontal shaft type, vertical shaft type, and inclined type. The correct use and adjustment of the rotary tiller are very important to maintain its good technical condition and ensure the quality of farming.

Horizontal shaft

It has a strong soil crushing ability and is mostly used for the cultivation of shrubland, marshland and grass wasteland. The working parts (see picture) include the rotary tiller roller and soil cutting blades evenly arranged according to the multi-head spiral, which is driven by the tractor power output shaft through the transmission device, and the common speed is 190-280 rpm. The direction of rotation of the knife roller is usually the same as the direction of rotation of the tractor wheel. The soil cutting blade cuts the soil layer from front to back and throws the soil block back and upward onto the casing and carriage to further break it. When the knife roller cuts and throws the soil, the reaction force of the soil on the knife roller helps to push the unit forward, so the traction required for the horizontal rotary tiller is very small, and sometimes the knife roller can even push the unit forward. Soil cutting blades can be divided into a chisel, machete, right angle knife, and arc knife.

 The front end of the chisel is narrow, it has a good ability to enter the soil, and the energy consumption is small, but it is easy to wrap the grass. It is mostly used in vegetable gardens and courtyards with few weeds. The curved blade of the machete has a sliding cutting effect, and it is easy to cut the grassroots without entanglement and is suitable for rice field farming. Right-angle knives have vertical and horizontal cutting edges, a wide blade, good rigidity, and easy manufacturing, but poor soil penetration performance. The arc knife has high strength, good rigidity, and a good sliding cutting effect. It is usually used on heavy-duty rotary tillers. When matched with tractors below 15 kilowatts, a direct connection is generally used instead of universal joint transmission; when matched with tractors above 15 kilowatts, three-point suspension and universal joint transmission are used; heavy-duty rotary tillers generally adopt traction. The tillage depth is controlled and adjusted by the carriage or the depth-limiting wheel. The carriage is located behind the knife roller, which has the function of crushing and leveling the soil; the depth limiting wheel is located in front of the knife roller. The configuration of the last-stage transmission device of the knife roller includes side transmission and central transmission. The side drive is mostly used for offset rotary tillers with small tillage width. The central drive is used for rotary tillers with larger tillage widths. The symmetry of the machine is good, and the force of the whole machine is even; however, the area under the transmission box cannot be reached by the cutting blades, which will cause the missing village. s installation.

Vertical shaft

The working part is a rotary tiller equipped with 2 to 3 spiral cutters. During operation, the rotary tiller rotates around the vertical axis, and the cutter cuts up the soil. It is suitable for paddy field hydroponic farming, with strong soil crushing and pulping effect, but poor covering performance. Used more in Japan.

In order to enhance the farming effect of the rotary tiller, various additional devices are installed on the rotary tiller in some countries. For example, a nail-tooth harrow is mounted behind the rotary tiller to enhance the effect of soil fragmentation, and a loosening shovel is installed to deepen the plowing layer.

Oblique

The rotary tillage working parts of the inclined rotary tiller are arranged obliquely in the horizontal plane, and the rotary plane of the rotary tiller blade is at a certain angle to the advancing direction of the machine-the oblique angle, and the rotary tiller blade has a relative movement along the axial direction when cutting the soil. The arrangement of single-row rotary blades on the knife shaft is related to the forward speed of the unit, the rotation speed of the knife roll, and the width of the knife edge. There is a certain phase difference between two adjacent rotary tillers on the same spiral line. The inclined rotary cultivator does not re-till when working, which relieves the soil constraints, thereby reducing power consumption and lowering tillage resistance.

 

The rotary tiller has the functions of breaking the bottom of the plow, restoring the structure of the soil plow layer, improving the ability of soil moisture retention, eliminating some weeds, reducing diseases and insect pests, leveling the ground, and improving the standards of agricultural mechanization operations.

A rotary tiller is a machine for separating the soil crust in areas grown with grain and commercial plants, for eliminating weeds, for presowing tillage of the dirt, and also for thinning sugar beet sprouts. As the toothed disks roll and also revolve over the surface area of the dirt, they pierce it without elevating the lower soil layers to the surface. which is additionally known as a rototiller, power tiller, rotavator, rotating hoe, or rotary rake, is a motorized cultivator. It works the soil using rotating blades or points and is either self-moved or attracted as an accessory behind either a two-wheel tractor or four-wheel tractor. A Rotary Tiller is an executive that uses its set of rounded points that are attached to a revolving shaft to dig into the dirt as well as transform it right into a seedbed that awaits planting.

 

People also know another product-the rotary cultivator, but the rotary cultivator and rotary tiller are not the same product.

 

A cultivator is primarily utilized to blend loosened soil, while a yard tiller can separate tough pieces of ground. Because its branches are not sturdy enough to loosen tough dirt, a farmer is not likely to function if you are developing a brand-new garden story.

 

Rotary tillers use a series of blades to plow the farm. These blades damage the soil, moisturize the soil and crush the soil, helping to prepare the soil for planting and obtaining high returns. It uses a set of blades to rotate and damage soil blocks, and it also helps to weed between crops.

 

The rotating tiller utilizes a set of bending points connected to a shaft powered by the tractor PTO to explore garden dirt, mixing it into a punitive, basically soil-free seedbed. You can adjust the working depth of the tiller by changing non-slip shoes. Generally speaking, the larger the tiller, the higher the optimal working depth.

 

Mechanical use

  1. At the beginning of the operation, the rotary cultivator should be in an elevated state, and the power output shaft should be combined to increase the speed of the cutter shaft to the rated speed, and then the rotary cultivator should be lowered so that the blades are gradually inserted into the soil to the required depth. It is strictly forbidden to combine the power output shaft or descend the rotary cultivator sharply after the blade enters the soil, so as to avoid bending or breaking the blade and increasing the load of the tractor.
  2. During the operation, the speed should be as low as possible, so that the quality of the operation can be ensured, the soil can be finely broken, and the wear of the mechanical parts can be reduced. Pay attention to whether there are noises or metal percussions from the rotary tiller, and observe the condition of broken soil and tillage depth. If there is any abnormality, the machine should be shut down immediately for inspection, and the operation can be continued after troubleshooting.
  3. When turning on the ground, it is forbidden to work. The rotary tiller should be raised to keep the blades off the ground, and the tractor throttle should be reduced to avoid damage to the blades. When lifting the rotary tiller, the inclination angle of the universal joint should be less than 30 degrees. If it is too large, it will produce impact noise and cause it to wear or damage prematurely.
  4. When reversing, crossing ridges and transferring plots, the rotary tiller should be raised to the highest position and the power should be cut off to avoid damage to the parts. If it is transferred to a distant place, the rotary tiller must be fixed with a locking device.
  5. After each shift, the rotary tiller should be maintained. Remove the dirt and weeds on the blade, check the tightness of each connecting piece, add lubricating oil to each lubricating oil point, and add butter to the universal joint to prevent aggravation of wear.

 

When it comes to functioning size, you want a tiller that is at the very least as large as the outdoors dimension of your back tractor tires. Otherwise, you might wind up with some areas in your yard that aren’t tilled along with others. So make sure you take note of each pass, seeing to it you overlap everyone.

 

Mechanical adjustment

 

  1. Horizontal adjustment left and right. Stop the tractor with the rotary tiller on the flat ground, lower the rotary tiller so that the blade is 5 cm away from the ground, and observe whether the height of the left and right blades from the ground is the same, to ensure that the blade axis level is consistent and the tillage depth is uniform during operation.
  2. Horizontal adjustment before and after. When the rotary tiller is lowered to the required tillage depth, observe whether the angle between the universal joint and the axis of the rotary tiller is close to the horizontal position. If the angle of the universal joint is too large, the upper pull rod can be adjusted to make the rotary tiller in a horizontal position.
  3. Lifting height adjustment. In the rotary tillage operation, the angle of the universal joint is not allowed to be greater than 10 degrees, and it is not allowed to be greater than 30 degrees when turning the ground. Therefore, for the lifting of the rotary cultivator, the use position adjustment can be screwed at the appropriate position of the handle; for the height adjustment, special attention should be paid when lifting. If the rotary cultivator needs to be raised again, the power of the universal joint should be cut off. .

 

If you’re beginning a brand-new yard, after that preferably you raked it in the autumn and also allow the reversed dirt to smooth over the wintertime. Spring is the moment to use the PTO-powered rotary tiller. Considering that this dirt has never ever been tilled in the past, you need to discuss it two or three times up and also is free of any type of big clods.

 

Whether you’re tilling a new yard or re-tilling one that probably hasn’t been grown in a while, begin gradually as well as don’t till unfathomable. Going also quick methods your tiller will not have time to grind the soil the means it should. When you have actually been over the ground a time or more, you can boost your rate as well as functioning deepness.

 

The tailgate on your tiller is additionally adjustable. A more open tailgate will certainly permit bigger dust clods to come out, providing you somewhat coarser dirt, as well as provide a much less degree surface. The kind of soil you have and what you plan to plant will certainly affect how coarse you desire the seedbed to be.

 

As well as keep in mind, constantly reviewed the Driver’s Handbook before running any tool as well as follow all operating and also safety and security instructions.
