Ground Drive Lock-Up
For liquid fertilizer ground drive lock-up, see page 44.
For seed meter ground drive lock-up, see page 45.
Dry Fertilizer Drive Lock Up (Option)
For transport, storage and planting without fertilizing,
lock up the fertilizer ground drive.
Note: Avoid operating the dry fertilizer meter when not
applying dry fertilizer.
Sharp Object Hazard:
Be cautious near the ground drive wheel. Wheel tines may be
sharp.
The dry fertilizer system is driven by a ground drive
wheel. When the planter is raised, a hydraulic cylinder
extends to raise the dry fertilizer drive wheel arm and
wheel out of ground contact.
For extended periods of time, the arm needs to be locked
up, or the wheel may slowly lower. A rotating lock arm
is provided that automatically engages when a lowered
drive arm is raised.
Refer to Figure 32
Remove the pin
holding the lock arm out of
engagement, allowing it to swing down. If the planter is
lowered, the lock arm engages automatically at next lift.
Dry Drive Re-Engagement
To disengage the lock arm, it may be necessary to
perform a brief lift operation to free the lock arm from the
tube projection.
Secure the lock arm with the clevis pin and hairpin cotter.
