INTRODUCTION
This mower deck can only be used for Park ma-
chines with a motor output of at least 16 hp.
The mower deck is available in two versions as
standard:
- with mechanical setting of the mowing height
(art. no. 13-2915)
- with factory-fitted, electrical setting of the
mowing height (art. no. 13-2921).
PREPARATIONS
Park models up to 1993:
A modification must be made to the machine to use
the mower deck:
1. Dismantle the return spring for centre steering
(fig 1).
2. Saw off the spring bracket, level with the frame
side member (fig 2).
3. Drill a new hole (Ø 8 mm), 8 mm from the lower
edge of the frame side member (fig 3).
4. Fit the spring in the new hole (fig 4).
ASSEMBLY
MOWER DECK
1. Bolt the mower deck to the attachment brackets D
(fig 5).
2. Hook the mower decks lifting spring E into the
attachment lift.
3. Connect the electrical contact to the outlet on the
side of the machine (applies only to art. no. 13-
2921), (fig. 6).
V-BELT
1. Set the height adjustment to an intermediate posi-
tion.
2. Lift the mower deck using the attachment lift.
3. Pull the v-belt over the machines central belt pul-
ley F (fig 7).
4. Tension the belt using the tension roller G. The
tension roller should be on the left of the belt seen
from the operators position.
5a. Park -1999:
Hook the tension roller spring H into the floor on the
right hand side (fig 7).
5b. Park 2000- :
Hook the tension roller spring H into the fastener,
just behind the front right wheel (fig 7).
SETTING
For the attachment to mow evenly and cleanly it
needs to be adjusted correctly:
1. Make sure the tyre pressure is correct:
Front: 0.6 bar (9 psi).
Rear: 0.4 bar (6 psi).
2. Place the machine on a flat surface. Loosen the
screws I (fig 8).
3. Adjust the mower deck so that the casings front
and rear edges are the same height from the floor.
4. Tighten the screws.

mowing height.
N.B. The stated mowing heights apply when the
machine is standing on firm ground.
MOWING HINTS
For the best Multiclip effect follow this advice:
- mow regularly.
- use full throttle on the engine.
- keep the underside of the mower deck clean.
- use sharp blades.
- do not mow wet grass.
- mow twice (using different mowing heights)
if the grass is long.
MAINTENANCE
PREPARATIONS
Unless otherwise stated, all service and mainte-
nance must be performed on a machine that is
standing still where the engine has been switched
off.
Prevent the machine from rolling, by al-
ways applying the parking brake.
Prevent involuntary engine start by al-
ways stopping the engine, loosening the
spark plug cable from the sparking
plug and earthing it. Remove the minus
(-) cable from the battery.
MAINTENANCE TIPS
To facilitate cleaning and maintenance of the
mower deck it can be folded up:
1. Set the mowing height adjustment to an interme-
diate position (= least tension on the drive belt).
2. Lift up the mower deck using the attachment lift.
3. Unhook the tension roller spring H (fig 7).
4. Pull off the v-belt from the central belt pulley F.
5. Loosen both locking pins J (fig 9).
6. Grip the mower decks frame (fig 10).
7. Fold up the mower deck until it stands upright
on the rear support plates (fig 11).
CLEANING
After use the underside of the mower deck should
be hosed down.
If grass cuttings have dried on to the mower deck,
scrape the underside clean.
If necessary touch-up the underside using a suita-
ble paint to prevent corrosion.
DRIVE BELTS
If any of the blades have hit a solid object (e.g. a
stone) the belt tension can change. This means that
the drive belt can, miss-mesh which in the long
term can damage the blades.
If necessary adjust the drive belt:
1. Unhook the tension roller spring H (fig 7).
2. Pry off the drive belt from the central belt
pulley F.
3. Dismantle the transmission casing.
4. Loosen the tension arm K (fig 12).
5. Loosen the bearing boxs fixing bolts L (fig 13).
6. Tension the drive belt by pressing the tension
arm backwards.
7. Tighten the tension arms fixing bolts.
8. Tighten the bearing boxs fixing bolts.
9. Carry out the same procedure for the other drive
belt.
When changing the drive belts, make
sure that the outer blades are always at
90° to the centre blade (see fig 14).
If you fit the drive belts incorrectly the blades will
collide as they overlap each other.
Always check the position of the blades after
changing the drive belt or adjusting the tension.
CHANGING BLADES
Use protective gloves to prevent cuts
when changing blades/blade tips.
Make sure the blades are always sharp. This gives
the best mowing results.
Always check the blade(s) after an impact. If the
blade system has been damaged the defective parts
must be changed. 
						

							ENGLISHGB
Always use original spare parts. Using
non-original spare parts can result in
the risk of damage even if they fit in the
machine.
The cutting system consists of three blade bars,
each with two interchangeable blade tips Y (fig
15). Both blade tips should be replaced at the same
time to avoid any imbalance.
Fit the new blade tips. Tighten the screws V and W
fully. Tightening torque: V - 9.8 Nm, W - 24 Nm.
And heavy impact can result in the blade tip being
folded aside. Loosen the locking nut X and turn the
blade tip back to its correct position. Mount a new
shear bolt V. Tighten the lock nuts X and Z.
