Landoll VT PLUS 7430, Operator'S Manual

Page: 61 / 84

4-6 GENERAL OPERATION
4-6.1 The horsepower requirements are typi-
cally 8-10 horsepower per foot of cut. This
will vary widely due to speed, depth, mois-
ture, residue and types of soils. Local deal-
ers can help in making recommendations for
your areas.
4-6.2 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 fur-
row.
4-6.3 Lift wheels must always be in contact
with the ground and carrying some imple-
ment weight. Lift wheels are used to gauge
the depth of each frame section and to con-
trol 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.
4-6.4 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.
4-7 FIELD OPERATION
4-7.1 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) .
4-7.2 Remove the wing lock pins and store in
the extra hole in the hinge bracket. Unfold
the wings and extend the fold cylinders com-
pletely
(See Figure 4-6).
CAUTION
FAILURE TO REMOVE WING LOCK
PINS BEFORE UNFOLDING WINGS
WILL CAUSE PERMANENT EQUIP-
MENT DAMAGE.
