Loss of Control and Crushing Hazards:
Lift or lower wheel by using ground blocks and planter
hydraulics. Use blocks that are stable front to back and side to
side to avoid the possibility of the wheel turning. Keep feet out
from under wheel. 90 pounds (41 kg) force is required to lift
wheel. If blocks are removed before pinning, or after
unpinning, the arm snaps down rapidly. The force of the wheel
impact can inflict serious injury.
The liquid fertilizer option uses a piston pump driven by a
ground contact wheel. When not using the fertilizer drive,
preserve the pump by locking up the ground wheel. On
older models remove the chain.
Refer to Figure 15
