Operation
Operation
This section covers general operating procedures
and adjustments necessary for the best field
performance and results. Experience, machine
familiarity, and the following information will lead to
efficient operation and good working habits. Always
operate farm machinery with safety in mind.
Even if drilling conditions rarely change, some items
need periodic adjustment due to normal wear.
Pre-Start Checklist
High Pressure Fluid Hazard
Escaping fluid under pressure can have
sufficient pressure to penetrate the skin.
Check all hydraulic lines and fittings before
applying pressure. Use paper or cardboard,
not body parts, and wear heavy gloves to
check for suspected leaks. If injured, seek
immediate medical attention from a
physician familiar with this type of injury.
Carefully review “
Lubricate drill as indicated under “
Check all tires for proper inflation. See “
Check all bolts, pins and fasteners. Torque as
shown in “
Check drill for worn or damaged parts. Repair or
replace parts before going to the field.
Check hydraulic hoses, fittings and cylinders for
leaks. Repair or replace before going to the field.
Rotate each ground drive wheel to see that the
drives and meters are working properly and free
from foreign material.
Make sure drive coupler is in place before
operating the drill.
Check that the caster pivots are unlocked.
Drill Raise and Lower
Raising and lowering the drill depends on the tractor
3-point lift arms in front, and hydraulic lift-assist at the
rear. When setup for field use, the hitch and lift
circuits may be operated in any order, or at the same
time. Both must be lowered for planting, and the
lowered hitch height must be as established. See
“
Raise Drill
Crushing Hazard
Depend on circuit neutral to hold the raised
drill only for field turns. Use parking stands
for all other raised operations, transport,
parking, maintenance, and storage.
1.
Raise the tractor 3-point lift arms fully.
2. Activate the lift circuit lever to extend the lift-assist
cylinder fully. Set the circuit to neutral.
3. If raising for planting after transport, parking, or
storage, remove the lock channel (1) from the
lift-assist cylinder. Store in the pin hole (2) at the
right side of the lift-assist.
Install the necessary stroke control spacers (3)
around the cylinder rod (4).
4. If raising for transport or storage, set lift circuit to
neutral to hold at raised. Set tractor parking brake
and shut off tractor.
5. Remove stroke control spacers (3) from lift-assist
cylinder rod (4). Store spacers on storage rod.
6. Install the lock channel (1) on the cylinder rod.
Secure with the pin.
7.
Start the tractor.
8. Slowly move the lift circuit lever to retract,
allowing the cylinder to settle on the lock (and
relieving pressure from the hydraulic system).
