OPERATION AND MAINTENANCE
•
As the individual units rotates, the resistance to
rotation increases as the degree of rotation
increases.
•
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 HSL has two depth gauges. One is directly in front of
the HSL machine, and one is directly behind it. The main
wheels and tires on the hitch, and the wing gauge wheels
and tires on the wing frames provide the forward most
depth gauge. The rear depth gauge is provided by the
reel/roller system the HSL was purchased with. The rear
gauge is available in three major types of different
offerings.

2. It is available in one of two different styles as a
twenty-three and a half inch (23-1/2") four leaf and
fixed hemisphere spring wheel reel.
3. It is available as a twenty-one inch (21") corrugated
rubber roller.
The depth of both the front and rear depth gauges is
controlled independently of each other. The front and
rear gauge depth controls are located on the hitch and
the left-hand wing frame respectively. Each utilizes a
master and slave hydraulic cylinder system.
For machines modified with tilt control and then built after
03/01/2018, the depth control is realized exclusively off of
the front main wheels and tires on the hitch in
combination with the wing gauge wheels and tires on the
wing frames. Since the rear reel is no longer required for
ultimate depth control the down pressure applied to it can
be adjusted to fit the conditions. Machines modified for tilt
control can be easily and quickly converted back into
conventional machines with depth reads front and rear.
