Why Is the Disc Harrow Working Depth Insufficient?

What are the reasons why the disc harrow blade does not enter the soil or the harrow depth is not enough? There may be several reasons why the disc harrow blade does not penetrate the soil or the harrow depth is insufficient:

(1) Soil texture is too hard or too soft: If the soil texture is too hard, the rake may not be able to penetrate deeply into the soil, resulting in failure to penetrate. On the contrary, if the soil is too soft, the rake may sink into the soil, which can also lead to failure to penetrate.

(2) Improper rake angle: If the rake angle is too tilted, it may slide out of the soil surface, causing it to not penetrate the soil. On the contrary, if the angle of the rake blade is too gentle, it may not be able to effectively excavate the soil, resulting in insufficient rake depth.

(3) Tractor traveling too fast: If the tractor travels too fast, the rake may not be able to fully excavate the soil, resulting in insufficient rake depth.

(4) Excessive soil moisture: If the soil moisture is too high, the soil may become too muddy, making it difficult for the rake to effectively excavate.

In response to the above reasons, the following measures can be taken:

(1) Adjust the insertion angle of the harrow: Based on the soil texture and cultivation requirements, adjust the insertion angle of the rake to better excavate the soil.

(2) Control tractor speed: Reduce the tractor speed appropriately to allow sufficient time for the rake blades to excavate the soil.

(3) Adjust soil moisture: Adjust soil moisture appropriately before cultivation to avoid soil being too muddy.

(4) Check the wear of the harrow blades: Regularly inspect the wear of the harrow blades and replace severely worn ones in a timely manner
