Operating Tips
Familiarization
Before mowing grass, practice operating the machine
in an open area. Start and stop the engine. Operate in
forward and reverse. Lower and raise the cutting units
and engage and disengage the cutterheads. When you
feel familiar with the machine, practice operating up
and down slopes at different speeds.
Warning System
If a warning light comes on during operation, stop the
machine immediately and correct the problem before
continuing operation. Serious damage could occur if
you operate the machine with a malfunction.
Mowing
The rotational speed of the cutting cylinders should
always be kept as high as possible in order to maintain
the highest quality of cut. This in turn requires that the
engine speed be kept as high as possible.
Cutting performance is best when cutting against the
lie of the grass. In order to take advantage of this fact,
the operator should attempt to alternate the direction
of mowing between cuts.
Take care not to leave uncut strips of grass at the
overlap points between adjacent cutterheads by avoiding
tight turns.
Quality of Cut
The quality of cut will deteriorate if the forward speed
is excessive. Always balance the quality of cut with
the work rate required and set the forward speed
accordingly.
Engine
Never let the engine labour. Reduce the forward speed
or increase the height of cut. Check that the cutting
cylinders are not in heavy contact with their bottom
blades.
Transporting
Always disengage the cutterhead drive when travelling
across un-grassed areas. Grass will lubricate the cutting
edges whilst mowing. Excessive heat will build up if the
cutting cylinders are run when not mowing and this
will cause rapid wear to take place. For this reason it is
also wise to reduce cutting speed when mowing lightly
grassed areas or when the grass is dry. Be careful when
driving between objects so you do not accidentally
damage the machine or cutting units.
WARNING
Take care when travelling over obstacles such as
roadside kerbs. Always travel at slow speed over
obstacles to prevent damage to the machines tyres,
wheels and steering system. Ensure that tyres are
inflated to the recommended pressures.
Slopes
Use extra care when operating the machine on slopes.
Drive slowly and avoid sharp turns on slopes to prevent
roll overs. Lower the cutting units when going downhill
for steering control.
Rear Roller Scrapers
It is generally wise to remove rear roller scrapers
where conditions allow, as optimum grass dis charge
is achieved without them. Scrapers should be refitted
when conditions are such that mud and grass start to
build up on the rollers. When refitting the scraper wires
care must be taken to ensure that they are correctly
tensioned.
