OPERATION AND MAINTENANCE
Hydraulic Disc Gang Lift System
The disc gang lift system must be purged of air before
beginning field operation.
1. Make sure the tractor's hydraulic reservoir is full of
the manufacturer's recommended oil.
2. Extend the lift cylinder and raise the machine.
3. Fully extend and retract the disc gang cylinder to
allow oil to fill cylinder.
4. Refill tractor hydraulic system.
IMPORTANT
Retracting the cylinders during periods of storage
will prevent rusting of shafts and subsequent
damage to seals.

General Operation
1. The horsepower requirements are typically 20-25
horsepower per shank. This will vary widely due to
speed, depth, moisture, residue and types of soils.
Local dealers can help in making recommendations
for your areas.
2. Operating speed is typically 4.5-6 mph. Excessive
speed can cause the unit to bounce, uneven depth,
and create undesirable ridges.
3. Lift wheels must always be in contact with the ground
and carrying some implement weight. Lift wheels are
used to gauge the depth and to control the leveling
feature.
4. Do not turn with the Disc Chisel in the ground. This
can put excessive side load on the gangs and hitch.
Raise the unit fully when making turns to prevent
gouging and pushing a ridge.
