Operation
Engage the PTO only when the tractor engine is at low revs to prevent shock damage
to the machine. Slowly increase the engine revs to achieve the standard 1000rpm PTO
speed.
If at any time serious vibration occurs, stop the engine immediately and check
that no blades are missing - following all safety precautions. The cause must be
found and rectified immediately or other components may be affected.
When in work, lower the machine to the ground carrying its weight on the skids,
allowing the machine to follow the contours of the ground and ensuring there is
sufficient slack in the wire rope. Select a sensible forward speed bearing in mind the
density of growth, the terrain, and the available horsepower, taking extra care when
turning, particularly on slopes.
When turning, it is not necessary to lift the machine off the ground but instead allow
sufficient room to turn in a large radius. The machine only needs to be raised when
turning in a tight corner or reversing over dense undergrowth, or when operating on the
front linkage.
Quality of finish is determined by the forward speed, i.e. a slow speed will produce a
high quality of cut, whereas faster forward speeds are used when high output is first
priority.
When operating in dense growth, particularly if cutting material more than 3” (75mm)
thick, it is possible to cut going backwards. To reverse over scrub use nudge bar to
push down material into the path of the blades. Proceed with caution where there is a
risk of hitting solid obstacles. In very heavy conditions under load it is better to take a
little at a time to prevent overloading the gearbox slip clutch.

Please observe Public Highway Regulations concerning the towing of implements, and
securely attach a registration and lighting board.
Take care to slow when travelling over rough ground and avoid bouncing the machine
on linkage, causing unnecessary strain.
