Operation
Engage the PTO only when the tractor engine is at low revs to prevent shock
damage to machine. Slowly increase the engine revs to achieve the standard
1000/540 RPM PTO speed, as indicated by the decal.
If at any time serious
vibration occurs, stop the engine immediately and check that no flails 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 head into float so that it drops to the ground, then
lower link arms until roller is in full contact with the ground. allowing the machine to
follow the contours of the ground with the head in float. 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.
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.
