Starting Mowing Job
Engage the PTO only when the tractor engine is at low revs to prevent shock load
damage to machine. Slowly increase the engine revs to achieve the standard 540
RPM 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 all its weight on the rollers,
allowing the machine to follow the contours of the ground. 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.
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 in work, always ensure the hydraulic spool valve that operates the mowing
decks is in float position to enable the decks to freely follow all contours of the
ground.
The constant velocity joint on the input PTO shaft can allow large joint angles up-to
80 degrees, this should only be allowed for a brief period, for example when turning
on headlands out of work. To extend the maximum working life of the PTO ensure
the joint angle is no more than 16 degrees @ 540 rpm under load.
Take care when turning not to run the tractor wheel against the mower drawbar or
the tractor lower links fouling the PTO, as this will result in serious damage.
Finishing Mowing Job
Stop tractor in level clear space and apply hand brake
Decrease engine revs to idle.
Disengage
PTO
drive
Raise decks to transport position.
If ‘roading’ machine to new mowing job follow road transport instructions
If parking the mower and tractor apply handbrake, stop engine and remove
key.
