Landoll 6250 Disc, Operator'S Manual

OPERATION AND MAINTENANCE
4-7
General Operation
1. The horsepower requirements are typically 8-10
horsepower per foot of cut. 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 a ridge on the outside edges. Too low of
speed may not allow the unit to properly fill in the
center furrow.
3. Lift wheels must always be in contact with the ground
and carrying some implement weight. Lift wheels are
used to gauge the depth of each frame section and to
control the leveling feature. Maximum discing depth
cannot be achieved by raising the lift wheels off the
ground. Little or no weight on the lift wheels will
cause the frame sections to gouge, side-draft, and
buckle producing inconsistent cutting depth.
4. Do not turn with the Disc in the ground, this can put
excessive side load on the gangs and hitch. Raise
the unit slightly when making turns to prevent
gouging and pushing a ridge.
Field Operation
1. Raise the unit to take the weight off of the transport
locks.
2. Remove the wing lock pins by sliding forward. Unfold
the wings and extend the fold cylinders completely
noting that the transport locks are also disengaged
(See Figure 4-6.)

CAUTION
Failure to remove wing lock pins before unfolding
wings will cause permanent equipment damage.
