Adjustment
Working Depth
Note: Ensure both tyres operate under the same working pressure (Recommended
4-6psi, 8psi for graders equipped with rear roller)
-
Move the grader to the arena that is suitable for test grading
-
Ensure the perimeter blade is in the parallel position
-
Lower the machine to the ground by engaging working position. Screw the working
height adjustment down so that it contacts the axle crossbar. Lift the machine of the
ground by engaging transport mode, and screw the adjuster down a further rotation.
This provides a good basis to begin with.
-
Move forward slowly to assess the grading depth, and adjust as necessary.
-
An element of trial-and-error is required to find the best settings for each arena,
and the optimum working depth will change through the year due to variables such
as surface temperature, water content etc.
-
Once you find a good depth setting for your arena, the screw adjuster can be left
in this position so that you can easily grade the arena next time with minimal adjust-
ment.
NOTE: The transport lever should ALWAYS be raised away from the working position
to adjust the working depth adjustment screw to prevent unnecessary cosmetic dam-
age to the axle assembly
