Purchase points (1) The support must be reasonable. Rotary cultivator power consumption should be lower than the output power of the supporting tractor. Rotary cultivator operation width should be able to cover the right and left rims of the matching tractor. After the three-point hanging rototiller is matched, it will have no impact on the stress conditions of the tractor front and rear wheels. . (2) Safe and reliable. The rotating part of the rotary cultivator shall have a safety shield and the shield shall be solid; when the rotary cultivator is placed alone, it shall be able to stabilize, and no external force shall be used to prevent tilting; the safety tamper symbol shall preferably be provided on the shell of the rotary cultivator. Complete and accurate instructions for use, including technical specifications, safety precautions, proper assembly and use and operation instructions or appropriate illustrations, adjustment methods and adjustment instructions, maintenance and care instructions, and troubleshooting for common problems Wait. (3) It can meet local agricultural requirements. Tillage should be able to meet certain cropping requirements for crop growth. Generally, the depth of tillage tillage should not be less than 10cm. (4) Good after-sales service. The place of purchase should be provided with maintenance and accessories sales services. The “Three Guarantees†service card for repair, replacement, and return must be provided at the time of purchase, and the after-sales service commitments should be in accordance with the “Responsibility for Repair, Replacement, and Return of Agricultural Machinery Products.†(5) The rotary cultivator products that have obtained the agricultural machinery promotion permit from the Ministry of Agriculture and affixed with the agricultural machinery promotion license certificate of the Ministry of Agriculture should be selected as far as possible. Use caution Rotary cultivators are characterized by high-speed rotation of the working parts, and almost all safety issues are related to this. Therefore, pay attention to the following points when using a rotary tiller. (1) Before use, check all parts, especially check whether the anti-rotation knife and the fixing bolt and the universal joint locking pin are reliable. If any problem is found, it must be dealt with promptly. (2) Before the tractor starts, the rotary cultivator clutch handle should be set to the disengaged position. (3) In the lifting state, the power is to be engaged. After the rotary cultivator has reached the predetermined speed, the unit may start and slowly lower the rotary tiller to make the rotary tiller into the soil. It is forbidden to start directly with the rotary tiller in case of soil, so as to prevent the rotary tilling knife and related parts from being damaged. It is forbidden to rapidly descend the rotary tiller, and it is prohibited to reverse and turn the rotary tiller after entering the soil. (4) When the ground turning does not cut off the power, the rotary cultivator must not be lifted too high, the transmission angle of the joints at both ends of the joint must not exceed 30 degrees, and the engine speed should be appropriately reduced. When transferring the land or walking long distances, the power of the rototiller should be cut off and locked after it is raised to the highest position. (5) When the rotary cultivator is in operation, it is forbidden to approach the rotating parts, and no person behind the rotary cultivator is needed in case the blade throws wounds. (6) When checking the rotary cultivator, the power must be cut off. When replacing rotating parts such as blades, the tractor must be turned off. (7) The speed of advancement during farming should be 2~3km/h in dry fields, and 5~7km/h in lands that have been ploughed or ploughed. Farming in paddy fields can be faster. Remember that the speed should not be too fast to prevent the tractor from being overloaded and damaging the PTO shaft. (8) When the rotary cultivator is in operation, the wheels of the tractor should be walked on the uncultivated land so as not to compact the arable land. Therefore, the wheel spacing of the tractor needs to be adjusted so that the wheels of the tractor are located within the working range of the rotary cultivator. Pay attention to the method of walking during operation to prevent the other tractor from compacting the cultivated land. (9) In the operation, if the knife shaft is too wrapped around the grass, it shall be stopped and cleaned in time to avoid increasing the load of the implement. (10) When rotating tillage, the tractor and the suspension part are not allowed to take people to prevent accidental injury by the rotary cultivator. (11) When using the walking tractor to rotate the cultivator, the tiller can be hung only when the subshift lever is in the “slow†position. If you need to reverse the work, you must put the subshift lever in the neutral position to hang the reverse gear. Rotary cultivating try not to use the steering clutch, apply push and pull handrails to correct the direction. When cornering, you should first reduce the throttle, hold the handrail frame, and then squeeze the steering clutch, do not turn dead bends to prevent damage to parts. Rotary cultivator maintenance Rotary cultivator maintenance is divided into class maintenance and quarterly maintenance, under normal circumstances, class should be carried out after each class maintenance, maintenance content includes: check the tightening bolts; check the pins, split pins and other consumables with or without defects, if necessary Replace; check the gearbox, ten bytes and bearings for lack of oil and replenish immediately if necessary. The quarterly maintenance should be carried out after each quarter of work is completed. The contents include: complete removal of dust and oil on the equipment; thorough replacement of lubricants and greases; check blade for excessive wear and tear, if necessary, replace new ones; inspect hoods, pallets, etc. With or without deformation, restore its original shape or change to new ones; comprehensively inspect the appearance of the equipment, make up the paint, machete, and spline oil on the shaft to prevent rust; when it is not used for a long time, the wheel-type tractor supporting rotating cultivator should be placed Level ground, must not be hung on the tractor.
