Cutting height adjustment is achieved by raising or lowering the two outer skid plates.
Lowering the skid plates produces a longer cut. Always set to equal hole settings from
front to rear and side-to-side.

To prevent gearbox damage, the PTO is fitted with a slip clutch. When cutting in
extreme conditions where solid objects are likely to be found, it is recommended the
operator reduces the engine revs to allow the blades to pivot more easily when striking
solid objects.
The clutch settings should not be altered without reference to the Spearhead Service
Department. Never over-tighten the pressure springs on the slip clutches. This could
result in severe damage to the gearbox and drive lines, as well as infringing on the
warranty.

If the machine has been laid up for any length of time, there is a risk of the clutch plates
rusting and seizing together. Never operate the machine in this condition, as there will
be no protection to the driveline and gearboxes against shock loading.
To free the clutch plates, first slacken all pressure spring bolts and run up the machine
for a short period. Deliberately try to cause the clutch to slip.
Finally, re-tighten the tension spring bolts to their original length, taking great care not
to over-tighten.
If in any doubt, consult Spearhead Service Department or your local Spearhead dealer
for further advice.
