MULCH MOWING
Mulching can save time, avoids gathering
piles of rotting cuttings and feeds your
lawn. It is however necessary to observe
certain rules to mulch mow successfully:
• Reduce the height of the grass by no
more than 1/3rd its height in each pass.
If the grass has grown long make
several passes to achieve the cut height
you require.
• Always cut with the throttle set to
FAST – mulching needs the full
running speed of the engine.
• Mow often, particularly in Spring and
early Summer. Short clippings of
25mm (1") or less decompose more
quickly.
• If possible avoid cutting in the wet.
• If an unsightly residue of cuttings is
being left – increase the cutting height.
• Vary the mowing pattern from cut to
cut.
• Always keep the underside of the
cutting deck clean to ensure good grass
flow.
• Always check that the blades are sharp
and in good condition – but do not
attempt to sharpen or replace them
yourself. New Countax blades are not
expensive and it is good practice to ask
your dealer to change them regularly.
There are five 20 Amp fuses on the
A20/50 Tractor.
1. 20Amp (yellow) for charging circuit.
2. 20Amp (yellow), ignition, safety
switches.
3. 20Amp (yellow) electric lift for Cutter
Deck and Auxiliary lift.
4.20Amp (yellow) located left-hand side
of the console is for net emptying circuit.
To check - remove fuse and check small
window, there should be an unbroken
metal strip bridging the gap (fig 4).
Note - If No.2 20Amp fuse blows when
the ignition key is turned this means there
is a short between the red and blue
coloured wire and the body of the Tractor.
The usual places to investigate are:
• The electrical PTO and socket.
• Seat switch wires (fig 3).
If fuses blow after these have been
checked, call your dealer.
PRINTED CIRCUIT BOARD
FUSES
There are 2 10Amp Blade fuses on the
circuit board (fig 5) which can be reached
by removing the cover (fig 1). These two
fuses control the lights and the
Electromagnetic Blade Clutch. If the
problem is not a fuse and you cannot see
any loose connections - call your dealer.
ELECTROMAGNETIC BLADE
CLUTCH
If the blade clutch disengages without
being switched off these are the possible
causes:
• You have got off the seat - the safety
switch will disengage the cutter.
• The battery has lost charge and will no
longer hold the clutch in operation.
• Fuse blown on Printed Circuit Board -
see above.
• Faulty Safety Switch or break in wire -
see your dealer.
