Technical Field

The invention relates to the field of rotary cultivators, in particular to a rear pressing trailing bar of a rotary cultivator.

Background

The rotary cultivator is widely applied to agricultural production at present. However, in the actual use process, after the soil is rotary tilled by the rotary cultivator, more floating grass is usually left on the surface of the soil, and the probability of plant diseases and insect pests is increased and the absorption of crops to nutrition is influenced by the excessive floating grass on the surface of the soil. In addition, larger soil blocks are sometimes left after rotary tillage of the rotary cultivator, and the larger soil blocks are also not beneficial to the growth of crops. In practice, float grass and large soil blocks are usually removed in a land harrowing mode after rotary tillage, but float grass needs to be manually cleaned after being collected on a harrowing device, so that manpower is increased, and time is wasted.
