The primary cause for the metering device not functioning properly is often due to improper meshing of the transmission gears or worn square holes in the gear components. In such cases, it's necessary to adjust or repair the transmission gears or the sorting gears to restore proper operation.
When individual seedlings fail to work, it's commonly caused by blockages in the seed shelf or seedling opening within a specific seeding box. These obstructions should be cleared to ensure smooth operation. Additionally, if the connecting pin between the seeding shaft and the seed sheave is broken, it must be replaced. In some cases, the seed box inserts may not open fully, so they should be manually pulled open to allow proper seed flow.
In situations where seeds are being planted but certain furrows remain empty, it’s usually due to clogged openers or seeding tubes. To resolve this, the blockage should be removed, and preventive measures should be taken to avoid debris from entering the openers in the future.
If a row stops working, the issue might stem from the clutch strut's release pin becoming disengaged or the separation gap being too small. To fix this, the release pin should be reattached and secured, and the separation gap should be adjusted accordingly.
Intermittent seeding or uneven seed distribution can occur when the meshing clearance of the transmission gears is too large, causing the gears to slip. Adjusting the meshing clearance can help stabilize the system. Another possible cause is a weak spring force in the clutch, which can also lead to slipping. In such cases, the spring should either be adjusted or replaced to ensure consistent performance.
