OPERATION AND MAINTENANCE

Leveling (Front-to-Rear)

1. The leveling feature on the VT Plus is used to keep

the machine level when raising the unit from a

working position to a transport position. The leveling

feature is also used to level the unit from front-to-rear

to perform a level discing operation in the field.

2. The unit should be level from front to rear and the soil

behind the disc should be level without furrows or

ridges. If there is a presence of a center ridge from

the rear gangs, the rear gangs are too deep. If there

is a furrow left from the rear gangs the front gangs

are too deep.

3. On machines with manual leveler adjustment, turn

the leveler handle in or out to adjust the front-to-rear

level (See Figure 4-12.) By turning the leveler

handle in (clockwise) will lower the rear gangs in

deeper. By turning the leveler screw out

(counter-clockwise) will raise the rear gangs.

NOTE

On the 7431, the variable link option is not available and

should not be adjusted. See Figure 4-13 for proper

location of leveler link. Set in 3rd hole down from top.

4. Implements with the optional hydraulic leveler, can

make adjustments on-the-go from the tractor. A

reference gauge is provided on the implement for a

guide.

IMPORTANT

Improperly set gauge wheels can prevent the leveler

from functioning properly. Large adjustments, either

manually or hydraulically will require adjustment of

gauge wheels.
