2 precautions for use
Rotary cultivators are characterized by high-speed rotation of working parts and almost all safety issues are related to this. So pay attention to the following points when using a rotary tiller.
(1)Before using, check all parts especially to check whether the rotary knife is installed with reversed and fixed bolts and the universal joint lock pin is reliable. If problems are found, it must be handled in a timely manner and confirmed before use.
(2) Before starting the tractor, turn the cultivator clutch handle to the disengaged position.
(3) After the power till the rotary cultivator reaches the predetermined speed in the ascending state, the unit may start and slowly lower the rotary tiller to make the rotary tiller into the soil. It is forbidden to start directly in the case of rotary knife to prevent damage to the rotary blade and related components. It is strictly forbidden to rapidly descend and turn the rotary tiller into the soil.
(4) Rotary cultivator shall not be lifted when cornering power is not cut. The transmission angle at both ends of universal joint shall not exceed 30 degrees and the engine speed shall be properly reduced. When transferring the land or walking long distances, the power of the rototiller shall be cut off and locked to the highest position.
(5) When the rotary cultivator is in operation, it is forbidden to approach the rotating part. No one behind the rotary cultivator can prevent people from throwing wounds in case of a blade.
(6) The power must be cut off when checking the rotary tiller. The tractor must be turned off when changing rotating parts such as blades.
(7) The speed of advancement during farming The dry land should be 2~3km/h, preferably 5~7km/h in the ground that has been cultivated or ploughed. Remember that speed must not be too fast to prevent the tractor from being overloaded and damaging the PTO shaft.
(8) When the rotary cultivator is working, the wheels of the tractor should walk on the uncultivated land so as not to compact the arable land. Therefore, the tractor wheelbase needs to be adjusted so that the wheels are located in the rotary cultivator work range. Pay attention to the walking method during the operation to prevent the tractor from compacting and cultivating another wheel.
(9) If the cutter shaft is wrapped around too much grass during operation, it should be stopped and cleaned in time to avoid increasing the load of the implement.
(10) The tractor and the suspended parts are not allowed to be used in rotation to prevent accidental injury by the rotary cultivator.
(11) Tillers can only be hung when the auxiliary shift lever is placed in the “slow†position when using the walking tractor with the rotary tiller. If you need to reverse the work, you must put the sub gear lever in the neutral position to hang the reverse gear. In the rotary tilling, try not to use the steering clutch to apply the push-pull handle bracket to correct the direction. When cornering the ground, you should first reduce the throttle and hold the handle frame and then pinch the steering clutch to avoid turning and bending to prevent damage to components.
