ADJUSTING THE CUTTING DECK
An even deck is essential for achieving a uniform cut over the whole lawn. With the lawnmower on a flat surface,
check the tyre pressure. To set the mower deck parallel to the ground use the appropriate rods (fig. 48, A). To
remove the deck from the mower, unhook the two side brackets (fig. 21, A) and the two pins (fig. 25). Unhook the
two side springs on the grass chute and pull forward the whole cutting deck, unscrew the loading duct from the
turbine. Caution! When refitting the deck always remember to reconnect the cardan joint. The load chute
must be screwed two complete turns and must not hit the turbine wheel.
PTO BELTS
CAUTION: These belts are special, ONLY USE GENUINE BELTS. To replace them, loosen the rod. To set the
tension use a no. 13 spanner on the nut that adjusting the tension spring (fig. 5, A). The spring must be compressed
at 92 mm length.
CLUTCH-BRAKE FOR PTO
The FD2200 TS is provided with a multi-disc electro-hydraulic clutch for PTO (fig. 51) activated by an electric push-
button on the dashboard (fig. 2 no.7).
During work, with the PTO engaged, the friction material discs are pressed against each other by the oil pressure.
To make this happen, the working pressure is calibrated at 9 bar. All clutches are tested in pressure to prevent oil
from leaking of theircomponents. This construction design guarantees a long working life and a gentle activation.
In order to meet security requirements, the clutch for PTO has a brake that stops the cutting blades within 7
seconds from the moment the clutch is disengaged. Due to the wear of the brake friction material (fig. 51 no.3)
blades may need more than 5 seconds to stop, in that case it is necessary to re-establish the distance between the
disc (fig. 51 no. 4) and the plate (no. 5) to 2.7 mm as per factory calibration.
How to carry out the calibration:
1) Turn off the machine.
2) Loosen the counter-ring (fig. 51 no. 1).
3) Shorten the distance between the disc (fig. 51 no. 4) and the plate (no. 5) to 2.7 mm by acting on the ring (no.2).
4) Lock the counter-ring (fig. 51 no.1) against the ring (no.2).
After adjusting it, make sure that the blades stop in less than 7 seconds. Should this not be the case contact an
authorized Grillo dealer because the machine does not meet the safety standards and cannot be therefore used in
a safe way.
GRASS CATCHER LOCK HOOK
The grass catcher lock hook is to be adjusted through the appropriate screw. Leave 2 mm clearance to make the
hooking easier when closing.
