Seedlings are not being sown properly. This issue is usually caused by the transmission gear not engaging correctly, or the square hole on the row unit becoming worn. To resolve this, check and adjust the gear alignment, repair any damaged parts, or replace the worn components if necessary.
Some of the metering devices are not functioning as they should. This could be due to blockages in the seed bins or metering device openings caused by debris. In such cases, clean the area and replace the seeds with fresh ones. Another possible cause is a broken connecting pin between the seeding shaft and the individual seed disc, which needs to be replaced. Additionally, if the seed box is jammed and not opening properly, manually pull it open to restore normal operation.
Seeds are being planted, but some rows have no seeds at all. This often happens when the opener or seed tube becomes clogged, especially on the opener that is attached to the ground wheel. Clean the blockage thoroughly and take preventive measures to avoid dirt or debris from entering the opener during operation.
Seeds stop and lose control during planting. This may occur if the clutch release pin is missing or the separation gap is too small. Reattach the missing pin and secure it properly, or adjust the gap to ensure smooth operation. Proper maintenance of the clutch system is essential for consistent seed flow.
Planting depth is uneven across the field. This can be caused by excessive meshing clearance in the transmission gears, leading to slippage. Adjust the gear clearance accordingly. Another common cause is a weak clutch spring, which also leads to gear slippage. In such cases, adjust the spring tension or replace the spring if needed to maintain proper engagement and consistent planting performance.
Regular inspection and maintenance of the planting equipment are crucial to prevent these issues. By addressing each problem promptly, you can ensure accurate and efficient seed placement, leading to better crop establishment and higher yields.
