Grass Cutting - Dolmar RM-72.13 H Operator's Manual

Hydrostatic transmission
Put the accelerator control between the «SLOW» and «FAST»
positions. Press the brake pedal to disengage the parking brake
and release the pedal.
Move the speed change lever in the «F» direction and go to the
required speed by using the lever and the accelerator.
The lever must be moved gradually as a sudden engagement of
drive to the wheels may cause tipping and loss of control of the
machine.
5.4.3 Braking
Mechanical transmission
To brake, first reduce the speed on the accelerator to avoid over-
loading the brake assembly and then push the pedal down fully.
Hydrostatic transmission
To brake, press the brake pedal which will simultaneously make
the speed change lever return to the «N» position.
5.4.4 Reverse
Mechanical transmission
The machine MUST be stopped before reverse can be engaged.
Push down the pedal until the machine stops and then insert re-
verse by moving the lever sideways and putting it into position
«R». Gradually release the pedal to engage the clutch and then
begin moving in reverse.
Hydrostatic transmission
The machine MUST be stopped before reverse can be engaged.
When the machine is stopped, start the reverse movement by
putting the speed change lever in the «R» direction.

5.5 GRASS CUTTING

5.5.1 Engaging the blade and forward movement
When you have reached the area to be mowed,
– put the accelerator into the «FAST» position;
– engage the blade by putting the lever into position «B»;
– to begin moving, operate the speed regulation controls taking care
to release the pedal very gradually and with particular caution as
already described.
Engage the blade with the cutting deck in the highest position, and
then gradually lower to the height required. To achieve good collec-
tion and even cutting of the grass, choose a forward speed to suit
the quantity of grass to be cut (height and density) and the lawn's
humidity, in line with the following indications (
transmission):
– High and dense grass - wet lawn
– Average condition grass
– Low grass - dry lawn
NOTE
The fifth gear is solely for moving from one
area to another on horizontal surfaces.
Hydrostatic transmission
The speed has to be adapted to the condition of the grass in a
gradual and progressive way by moving the speed change lever.
The speed should always be reduced if you note a reduction in en-
gine speed, since a forward speed that is too fast will not cut the
grass well.
Disengage the blade and put the cutting deck in the highest position
whenever you need to get past an obstacle.
