Rotary cultivator purchase, use and maintenance

Rotary cultivator is a farming machine that uses tractor's power to drive rotary blade to cut soil. Compared with other tillage machines, rotary tillage operation has the characteristics of good soil performance, high work efficiency and high operation quality, and the operation can reach the level of soil and ground. purpose. Divided by matching tractors, rotary cultivators can be divided into walking tractors and rotary cultivators. The rotary cultivators for hand-held tractors have a small ploughing range and a slow operation speed. They are mainly used in the operation of small plots in the south, and the cultivating range of rotary cultivators for wheeled tractors is relatively large and the operation efficiency is high.

China's rotary cultivators started in the late 1970s and early 1980s. Now, there are more than 100 manufacturers of rotary cultivators across the country, and more than 400,000 rotary cultivators are produced each year. Product specifications and models complete, spare parts supply. Lianyungang in Jiangsu, Nanchang in Jiangxi, Weifang in Shandong and other places are the main producing areas for wheeled tractors supporting rotary cultivators. The production of rotary cultivators for hand-held tractors is mainly distributed in Jiangsu, Zhejiang, Anhui, and Guangxi, where rotary cultivators are used. There is a growing trend.

When the rotary tiller is stuck in a car, it is forbidden to stand in front of the machine to lift the machine when the flame is not turned off. The machine is too high and the field pick-up shall turn off the fire.

,maintenance. “The principle of prevention and maintenance of weight and cultivation” is the principle of the use and maintenance of rotary cultivators. The maintenance of rotary cultivators is divided into class maintenance and quarterly maintenance. Under normal circumstances, class maintenance should be carried out after each class of work. The contents include: 1 Check the tightening of the coupling bolts; 2 check for flaws in the consumables such as machete, bolts and cotter pins, and replace them if necessary; 3 check if the gearbox, universal joints and bearings are short of oil and replenish them immediately if necessary. Quarterly maintenance should be carried out after completion of each work season. The contents include: 1 Thoroughly remove the dust and oil on the equipment; 2 Replace the oil and grease; 3 Check whether the blades are excessively worn and replace them if necessary; 4 Check the hood, Whether or not the pallets are deformed, restore their original shape or change to new ones; 5 Fully inspect the appearance of the implements, add paint, machete, and spline oil on the shaft; 6 When the wheel is not used for a long time, the wheeled tractor shall be equipped with a rotary tiller Place on level ground and do not hang on the tractor for long periods of time to avoid deformation of the joint parts.
