Once ready for work,
raise the mower cutting
height
and
slowly
engage the PTO with
the
tractor engine at low
revs to prevent shock
damage to the machine.
Slowly
increase
the
engine revs to achieve
the recommended PTO
speed of 1000r.p.m. As
indicated by the decal
on top of the centre
guard
and
not
the
number of splines on
the P.T.O shaft. If at any
time serious vibration occurs, stop the engine immediately and check the blades,
following all safety precautions. Select a sensible forward speed bearing in mind
the density of growth, the terrain, and the available horsepower.
The quality of finish is determined by the forward speed, i.e. a slow speed will
produce a high quality of cut, where as faster forward speeds are used when high
output is first priority.
When in work, always ensure the hydraulic spool valve that operates the folding of
the wings is in float position to enable the wings to freely follow all contours of ground
(Fig. 6).
