Description

technical field

[0001] The invention relates to an agricultural tractor, in particular to a rear-mounted rotary tiller of the agricultural tractor. Background technique

[0002] A rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil breaking ability and flat surface after plowing. At the same time, it can chop up the root stubble buried below the surface, which is convenient for the seeder to operate and provides a good seed bed for later sowing. According to the configuration of the rotary tiller shaft, it is divided into three types: horizontal axis type, vertical axis type and oblique type. The correct use and adjustment of the rotary tiller is very important to maintain its good technical condition and ensure the quality of farming. The rotary tiller has the functions of breaking the bottom of the plow, restoring the structure of the soil plow layer, improving ...
