- A need for careful attention when you use a
“ride-on” class mower.
- The loss of traction on slopes or in a
condition of decreased traction is not
corrected by an application of the brakes.
Reasons for the loss of control.
i) Not enough wheel grip.
ii) Driving at more than the safe speed for the
conditions
iii) You over brake or brake suddenly.
iv) The type of machine is wrong for the job.
v) No attention given to the ground conditions
or operating slopes.
vi) Incorrect hitch and load distribution.
1.2 PREPARATION
a) When you operate the mower, always wear
strong footwear and long trousers. Do not
operate the equipment without the correct
footwear.
b) Inspect the cutting area for any objects in
the area. Remove these objects. These
objects can damage the blades or cause

- Do not stop or start suddenly when you
operate on a slope.
- To operate on a down slope, prevent sharp
movements on the controls and always
keep the machine in gear.
- Go slowly when you operate on slopes and
when you make tight turns;
- Look for any changes in the cutting surface
that can change the mowers balance.
- Never use the mower to move across a
slope on a diagonal line. Unless the
machine is for this purpose;
f) When you pull a load or use accessories,
be careful.
- Use only approved drawbars;
- Any load must not change your full control
of the machine.
- Do not turn suddenly. Be careful when you
move in a reverse direction;
- Use the counterweight or wheel weights
recommended in the instruction handbook;
g) Be careful of those around you and the
users of the road when you move across or
near roadways;
h) Stop the blades before you move across
any surface different from grass;

Cutting height can be different from the set height. The
given height of cut depends on the turf condition,
caster tire pressure and other conditions. If you
operate on a rough surface, low cutting heights can
cause “Scalping”. Adjust the height of cut to prevent
turf damage.
1. Park the mower on a flat and level surface. Lift the
deck until the caster wheels are 3-4 in. (75-100
mm) off the ground. Stop the engine and remove
the key. Put stops below the deck so that it is held
safely.
2. Fit the Push-arm pin (A) into indicated hole.
Fasten with hair pin (B). Repeat for the other
Push-arm.
