Operating Instructions
22
Drill Lift/Lower (s/n A1058W-)
(applies to drills with serial numbers A1058W-
for serial number , see page 21)
Raising and lowering the drill relies on the tractor 3-point
lift arms in front, and hydraulic lift-assist cylinders 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 6 on page 17.
Raising
1.
Raise the tractor 3-point lift arms fully.
2.
Activate the lift circuit lever to Extend the lift-assist
cylinders fully. Set circuit to Neutral.
Crushing Hazard:
Rely on circuit Neutral to hold the drill raised only for field
turns. Use lock channels for all other raised operations,
transport, parking, maintenance and storage.
Raising after Transport, Parking or Storage
3.
If raising for planting, remove lock channels
from
lift-assist cylinders. Store in the pin holes
of the
inside plates of the lift assist riser weldments.
4.
Install stroke control spacers
. Remove needed set
from rods
on lift-assist weldments and clamp
around cylinder rods
. Use a locally developed
spacer combination (see page 19).
Raising for Transport, Parking or Storage
5.
If raising for transport or storage, set tractor parking
brake and shut off tractor.
6.
Remove stroke control spacers
from lift-assist
cylinders. Store spacers on weldment rods
.
If recently developed or changed, make a note of the
combination removed.
7.
Remove lock channels from
the riser weldments.
Install them on the cylinder rods. Secure with pins.
8.
Slowly move the lift circuit lever to Retract, allowing
the cylinders to settle on the locks (and relieving
pressure from the hydraulic system).
