Once complete the blade will then be able to scrape the remaining surface in towards the machine and level accordingly,
depth stop if necessary – it is better to make two passes with the grader set to a lesser working depth, than one deep pass, and a more
consistent surface will result.
Make one pass around the edge of the site and repeat as many times as necessary to draw material away from the edge boards – more passes
will be required when a lot of circular schooling work has been going on. Ensure that the blade or running wheel does not contact the edge
boards excessively in order to avoid any potential damage. Beware of obstructions such as gateposts which could damage the machine or vice-
versa
The corners of the arena can be graded by raising the grader into transport position, reversing into the corners, and lowering. Again, it may be
necessary to repeat this action to ensure level corners. Smaller towing vehicles such as ATV's can effectively
2 Primary Grading
Once perimeter grading is finished, place the perimeter blade back into its upright original position.
The first main grading operation should always be along the direction of the longest edge of the arena. Remove or move all obstacles before
beginning to ensure the entire area is levelled consistently.
To work heavily used areas, for example where jumps have been placed, grading in circular or figure-of-eight patterns can aid quick grading, and
restore a consistent surface finish.
3 Secondary Grading
It is recommended that, time permitting, a second grading pass is undertaken to ensure the desired surface finish and feel. This should be
conducted in exactly the same manner as the primary grading operation, but in rows drawn at either 45° or 90°.
The choice of secondary grading direction will in part be down to the design of the site being levelled, and may not in reality be practical. to grade
at 45° or 90° In this case it is recommended to grade at 180° from the first grading direction (i.e. working from the opposite starting edge, to
ensure complete coverage).
