Technical points of practical operation of rotary cultivator

Date:2018-04-08 Author: Click:

The rotary tiller is a ploughing machine that is equipped with tractors to complete ploughing and raking operations. Because of its strong ability of breaking soil and flat surface after ploughing, it has been widely applied. Correct use and maintenance of rotary tiller is particularly important to maintain its good technical status and ensure the quality of cultivation.



Correct use

1. start.

In order to join the power under the lifting condition, the unit can start only after the rotary tiller reaches the predetermined speed. It should be as slow as possible, so that the quality of operation can be guaranteed, the soil can be fine broken, and the wear and tear of the machine parts can be reduced. Listen carefully to whether there is noise or metal knocking in rotary tiller, and observe the condition of soil breaking and tillage. If abnormal, the engine should be immediately flameout to ensure personal safety and then check. After troubleshooting, you can continue your homework.

2. turn.

When turning the ground, it is forbidden to operate. The rotary tiller should be lifted so that the blade leaves the ground and the tractor throttle should be reduced to avoid damage to the blade. The tail wheel and steering clutch should cooperate with each other and proceed slowly. No sudden turning is allowed to prevent damage to relevant parts. When the rotary tiller is hoisted, the inclination angle of the universal joint should be less than 30 degrees. When the inclination angle is too large, the impact noise will be produced, which will cause premature wear and tear or damage.

3. reversing and transferring.

When reversing the vehicle, crossing the ridge and transferring the plot, the rotary tiller should be raised to the highest position and cut off the power. So as not to damage the machine parts. For distant transfer, the rotary cultivator should be fixed with locking device.


1. the load of rotary tiller is too large.

It is caused by excessive tillage, sticky and firm soil. Elimination method: reduce tillage depth, reduce the speed of the unit and the speed of the coulter.

2. the rotary tiller runs when it works.

It is caused by hard soil or incorrect blade installation. Troubleshooting: reduce the speed of the unit and the speed of the cutter, and install the blade correctly.

3. the ground after rolling is uneven.

The reason is that the speed of the unit is incompatible with the shaft speed. Elimination method: appropriately adjust the speed between the two.

4. the rotary tiller works with metal percussion.

The main reasons are as follows: the transmission chain rubs against the transmission box after being loose; the blades on both sides of the plough shaft, the left arm or the transmission box collide with each other after being deformed; the blade fixing screw is loose. Elimination: Adjust the tension of transmission chain, rectify or replace seriously deformed parts, tighten loose screws.

5. the Coulter gearbox has a noise.

It is caused by foreign objects falling on the installation or damage of teeth of bearings and gears. Elimination: try to remove foreign bodies or replace bearings or gears.

6. the rotary cultivator intermittently throws large soil blocks.

The main reasons are: blade bending deformation, blade breaking, loss or serious wear. Exclusive method: correct or replace blades.

7. the tiller shaft of the rotary tiller is not moving.

Rotary cultivator

The main reasons are: gear or bearing bite dead; left arm or transmission box deformation, plough shaft bending deformation; transmission chain broken or plough shaft wrapped in grass and mud serious. Elimination: correct, repair or replace badly deformed and damaged parts.

Scientific maintenance "prevention is more important than cure, maintenance is more important than repair" is the principle of the use and maintenance of rotary tiller, rotary tiller maintenance is divided into on-duty maintenance and quarterly maintenance.

1. when duty is maintained normally, classes should be maintained after each shift.

Check tighten the connecting bolts.

(2) check the defects of the damaged parts such as machetes, pins and pins, and replace them if there is any damage.

Check whether the transmission box, universal joint and bearing are short of oil. When oil is lacking, they should be replenished immediately.

The 2. quarter maintenance should be carried out after each operation quarterly, including:

(1) thoroughly remove dirt and oil from machine tools;

Replace lubricating oil and grease;

Check whether the blade is excessive wear, and replace the new blade when necessary.

Check whether there is any deformation of the hood and trailing board, and restore the original shape or replace it if necessary.

(5) check the appearance of the machine thoroughly, add paint and oil and rust on the scimitar and spline shaft.

_When it is not used for a long time, the rotary tiller with wheeled tractor should be placed on the horizontal ground and not be suspended on the tractor for a long time, so as to avoid deformation of the connecting parts.
