Caster Locks - Field Operations
For planting in conditions ranging from flat ground to
moderate slopes, the caster locks may be left in the
ROAD position, allowing the casters to pivot freely, and
simplifying fold/unfold operations.
For planting across extreme hillsides, where side drift
might occur, lock the casters after unfolding:
1. Move the lock handle
from ROAD to FIELD at
each caster.
The lock arm will automatically capture and hold the
pivot plate detent when the product next moves.
See page 32 for unlocking steps.
