Lock Up Fertilizer Drive
YP40 serial number B1072A+
Loss of Control and Sharp Object/Crushing Hazards:
Do not lift or lower wheel by spoke or rim; use handle only.
Keep feet out from under wheel. 90 pounds (41 kg.) force is
required to lift wheel. If you lose your grip before pinning, or
after unpinning, the arm snaps down rapidly. The traction
teeth and 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.
Note: Do not operate planter pump when not applying
material.
Refer to Figure 14

6. Release the lock arm , lift handle to lift ground
wheel up to position it in-between lock arm.
