Field Operation - Landoll VT Plus 7550 Operator's Manual

OPERATION AND MAINTENANCE

Field Operation

1. The horsepower requirements are typically 10-12
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.
5. The gang angle is intended to be changed while
being pulled through the field. The more aggressive
the angle, the more horsepower it will take to pull the
7550. The gang angle may be adjusted from 5 to 15
degrees and gang adjust gauge is located on right,
front inner wing and is visible from tractor
Figure 4-7.).
