Disabling Unused Drives
To reduce wear on unused components, the various
drive systems can be disabled at various scales.
Circumstances which call for this include:
• Calibration (testing one system while avoiding material
loss at others)
• Seeding without application of fertilizer and/or
treatments
• Fertilizer and/or treatment application without seeding.
Wing Drive Lockup
Crushing and Sharp Object Hazard:
This is a two person operation. Wear gloves. Keep legs and feet
out from under the ground drive wheel. If a grip is lost, the
ground drive wheel will snap down with considerable force.
Be careful around the drive wheel teeth. They may be sharp.
Refer to Figure 39
To prevent drive operation when the planter is lowered:
1. Move the planter to field conditions. Unfold and
lower.
2. At each wing, lift the ground drive arm at the
handle
provided.
3. Swing down the hook and engage the wheel rim.
4. Lower the wheel into engagement with the hook.
