General Operation; Field Operation - Landoll VT Plus 7431 Operator's Manual

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 6 - 9 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 VT Plus 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.
OPERATION AND MAINTENANCE

Field Operation

1. Raise the unit to take the weight off of the transport
locks. Remove the transport locks from the lift
cylinders (on the main frame only). Store the
transport locks on the retainers above the main lift
(See Figure 4-4.)
2. Remove the wing lock pins and store in the extra hole
in the hinge bracket. Unfold the wings and extend the
fold cylinders completely (See Figure 4-6.)

Failure to remove wing lock pins before unfolding
wings will cause permanent equipment damage.
