5. Once complete the blade will then be able to scrap the remaining surface in
towards the machine and level accordingly,
adjusting the 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.

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.
