10.10 DRIVING ON SLOPES
Driving on slopes is very demanding for the
operator, as they constantly have to evaluate
information about the movement of machine and
the character of the terrain. Especially important is
the wheel adhesion to the grass or other surface
and the mower tilt angle.
Pay attention to climatic conditions.
The climbing ability of the mower will be radically
different on dry, wet or moist grass slopes.
The mower may work on the
recommended slopes (see chapter 2.2)
only when the surface (grass) is dry. If
the grass is wet or moist, the maximum slope, on
which work is permitted, is 20 degrees.
Examine closely the working area. Evaluate the
situation and test the possibilities and
characteristics of the specific terrain. Do not take
chances. If the mower loses traction, you have lost
control, stop mowing and re-evaluate the
conditions.
The driving wheels of the mower must be evenly
inflated to the maximum value allowed by the tyre
manufacturer. Maximal 250 kPa / 2,5 bar / 36 PSI
Start your work at the bottom of the slope and
proceed to the top. This way you will be usually
moving from less to more steep slopes, which will
give you a better chance to evaluate the climbing
ability and make the right decisions concerning
further work. If you begin to mow steeper slopes
first, it may happen that – due to adverse
conditions - the mower will slip on the slope. Due
to dynamic effects the mower may even roll over.
The method of cutting from the top of the hill to the
bottom should only be used exceptionally when the
operator is in detail acquainted with the terrain.
If the mower is slipping, do not try to stop it and do
not approach it, especially the area below the
mower.
Do not touch or approach the mower if the wheels
are lifted, the mower tilted, in an unstable position
or starting to roll over.
Before operating on slopes, make sure that no
one is below the mower or the working area.
Do not endanger third persons by the
movement of the mower.
Choose your operating position away from the
area to which the mower may slide or to which
the mowed grass may be thrown. The
direction of the discharged grass may change
while operating according to the driving
direction of the mower.
When working on slopes, avoid the
following:
• Sudden sharp acceleration, steering or
braking
• High driving speed
• Uneven ground
• Changing adhesion (moving from areas
exposed to sun to shade)
• Driving over the mowed material
• Reduction of engine speed
• Stopping on a slope and shutting off the
engine.
10.11 STOPPING THE MACHINE ON
A SLOPE
In case you are forced to stop the mower on a
slope and need to interrupt you work, stop the
engine etc. be sure to position the wheels
across the slope. This will prevent possible
movement of the mower down the slope.
10.12 SKID STEERING
Slope mower Spider ILD02 is equipped with
the skid steering function. This function allows
machine rotation around its vertical axis by
driving wheels in opposite directions. This
function can be activated by controller 10
under the condition that the wheels are
positioned in the straight direction (see the
figure below). If these conditions are met then
the mower can be rotated using controller 8
(driving forward/backward). By moving the
joystick forward the mower rotates clockwise,
by moving it backwards the mower rotates
counter clockwise.
