Drill Lift/Lower (s/n A1059W+)
(applies to drills with serial numbers A1059W+
For serial number A1058W-, see page 21)
Raising and lowering the drill relies on the tractor 3-point
lift arms in front, and hydraulic lift-assist cylinder at rear.
When setup for field use, the hitch and lift circuits may be
operated in any order, or simultaneously. Both, however,
must be lowered for planting, and the lowered hitch
height must be as established at step 15 on page 16.
Raising
1.
Raise the tractor 3-point lift arms fully.
2. Activate the lift circuit lever to Extend the lift-assist
cylinder fully. Set circuit to Neutral.
Crushing Hazard:
Rely on circuit Neutral to hold the drill raised only for field
turns. Use parking stands and lock channel for all other raised
operations, transport, parking, maintenance and storage.
Raising after Transport, Parking or Storage
Refer to Figure 10 and Figure 11
3.
If raising for planting, remove lock channel from
lift-assist cylinder. Store in the pin hole of the right
side of lift assist weldment.
4. Install stroke control spacers . Remove needed set
from rod on lift-assist weldment and clamp around
cylinder rod . Use a locally developed spacer
combination (see page 17).
Raising for Transport, Parking or Storage
Refer to Figure 10 and Figure 11
5.
If raising for transport or storage, set lift circuit to
neutral to hold at raised. Set tractor parking brake
and shut off tractor.
6. Remove stroke control spacers from lift-assist
cylinder. Store spacers on weldment rod .
Note: If recently developed or changed, make a note of
the combination removed.
7. Install lock channel on cylinder rod. Secure with
pin.
8. Start tractor.
9. Slowly move the lift circuit lever to Retract, allowing
the cylinder to settle on the lock (and relieving
pressure from the hydraulic system).
