First, the causes of plowing issues:
(1) Before plowing, no field cleaning or clearing was done, leaving debris and obstacles in the field that could cause the plow to drag.
(2) During the plowing process, if the plow started dragging, the operator failed to address the issue promptly, leading to further complications.
(3) The soil may be too hard, or there might be a thick layer of grass roots, making it difficult for the plowshare to penetrate the ground effectively.
(4) A worn-out plow blade or insufficient vertical clearance at the blade tip can reduce the efficiency of the plow and lead to poor performance.
(5) Severe deformation of the plow shaft can cause imbalance and improper operation, contributing to the plow dragging or not working properly.
(6) Incorrect depth adjustment or misalignment of the plow during operation can result in uneven plowing and increased resistance, causing the machine to run improperly.
Second, the solutions to these problems:
1. Before starting the plowing operation, the crew should ensure the field is clear of any obstructions. If the plow starts to drag during work, the issue must be addressed immediately to prevent further damage or inefficiency.
2. Regular maintenance and proper adjustment of the plow components are essential. This includes checking and repairing the plowshares, blades, lifting mechanisms, and ensuring all parts are in good working condition. The plowshare should be extended as needed, and the blade should be sharpened regularly. The three key clearances—the tip, the wing, and the plow bed—must be stable to maintain proper functionality. The blade clearance should be between 8–10 cm, and the vertical clearance should be 10–15 cm. This ensures efficient cutting and good contact with the ground. Additionally, the horizontal clearance should be around 8–10 cm to improve lateral plowing and stabilize the plow during operation.
3. To avoid the plow getting stuck when turning, especially in tight corners, it’s recommended to first plow along the edge of the field, flipping the soil outward. This helps the plow move more smoothly and prevents it from getting caught.
4. In cases where the soil is very hard or compacted, pre-plowing the area can help loosen the ground, allowing the plowshare to enter more easily and reducing the length of the unworked strip.
