REAR THREE POINT HITCH PREPARATION
The hitch system gives position control and load control of soil engaging implements.
Your tractor could be, depending upon customer specification, able to accept either Cat II or Cat IIIN
implements, conforming to SAE-ASAE standard dimensions. If your tractor is equipped with a Cat IIIN
hitch, the hitch can be converted to accept Cat II implements with the use of either reducer bushings,
one for each lower link and one for the top link or alternative linkage balls, all of which are available from
your dealer.
.
When using the three point hitch ensure there is sufficient clearance between the rear tyres and the lower
links by adjusting the stabilizers and/or tread positions.
The top and lower links must be adjusted correctly so that the implement can work at the required depth and
that the lower links are free to move up and down with the shape of the ground.
After making any adjustments, carefully raise the implement to make sure there is clearance between the
tractor and implement.
Make sure tyre pressures, wheel equipment and ballasting are correct before making hitch adjustments.

WARNING: Extreme care must be exercised when adjusting and checking
the hitch and control linkage when the engine is running and when linkage
is under hydraulic or mechanical load. Study the linkage and hitch travel,
keep hands, arms, legs and feet out of the travel arc of the hitch and
linkage. Make sure that no persons are in the danger area.
