1) The machine has the characteristics of convenient space adjustment and easy depth adjustment. Its structure is reasonable, durable, easy to use, easy to maintain and can meet the agronomic requirements of intensive farming.

2) The machine adopts double spring tension device, in which the plow tip can automatically bounce up when it encounters obstacles in the working process, and quickly restore its original working state after crossing, thus playing the role of protecting the plow tip. The vibration of plough legs caused by uneven soil resistance is helpful to reduce the matching power.

3) The machine can install two types of plough tips: deep-loosening plough tips and loosening shovel, so that the machine can be applied to middle tillage, loosening soil, moisture conservation, weeding and other operations of field crops.
