Landoll 7822 Series Operator's Manual page 18

OPERATION & MAINTENANCE
• The front row fractures soil to the left side of each of
the front blades, while the rear row fractures soil to
the right side of each of the rear blades.
• As a result, each blade, in each row is moving soil in
the same direction as the others in that row. Because
of this, the HSL creates and maintains a level field.
The primary depth control of the HSL is directly in front of
the machine. The main wheels and tires on the hitch, and
the wing gauge wheels and tires on the wing frames
provide primary depth gauge.
The HSL is equipped with a reel/roller system that
stabilizes the machine, reconstitutes the worked soil and
provides a finished characteristic to the reel/roll
purchased.
