Leveling (Front-To-Rear) - Landoll 7430 Series Operator's Manual

4-9 LEVELING (FRONT-TO-REAR)

4-9.1 The leveling feature on the Vertical Har-
row 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.
4-9.2 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.
