Caster Pivot Locks (s/n A1058W-)
(applies to drills with serial numbers A1058W-
for serial number A1059W+, see page 23)
To prevent side movement of the drill when transported
by trailer, the lift-assist casters may be locked in their
full-trailing or full-reversing orientations.
Use this feature only for trailer transport. Do not use
these locks for semi-mounted 3-point towing or field
operations.
Locking Casters
Refer to Figure 15
1.
With drill hitched, raise both tractor 3-point lift arms
and rear ends (page 21). Install lift lock channels
.
2. Pull or back drill onto trailer bed.
Note: On extremely narrow trailer beds, it may be
necessary to lock the casters before moving the
drill onto the trailer. Make sure drill is precisely
aligned for the final move, as maneuverability is
greatly reduced with lock pins in place.
3. Pull forward, or reverse, until casters are in desired
orientation, and a lock plate cutout
is aligned
under each lock tube .
4. At both left and right lift assist arms, remove the
retaining pins
, allowing the locking pin to fall
into the lock plate cutout.
5. Store the retaining pins in the lock channel storage
holes
of the lift assist riser weldment.
6. Lower drill.
Unlocking Casters
Refer to Figure 15
1.
Hitch drill before unlocking.
2. Leave the lock pins in place until the drill is removed
from the trailer, unless the trailer bed has more than
ample width to permit casters to safely make a full
turn.
3. Retrieve retaining pins from storage locations.
4. Lift lock pins out of lock plate holes.
5. Align hole in lock pin with hole in upper lock tube .
Secure lock pin with retaining pin .
