Adjusting The Cutting Deck - Grillo FX27 Zero turning Manual De Instrucciones

- check that the cutting deck has finished the tilting phase and is parallel to the ground;
- check that the red blocking levers are well lubricated with grease;
- increase the load on the spring for the cutting deck floating by screwing the adjustment knob (fig. 1, no. 8).
If this does not give a result:
- loosen the four bolts on the tilting hinges (fig. 15, ref. A) and adjust the concentricity of the holes of the
blocking levers until they are inserted. When the operation is completed, screw the tilting hinge bolts tightly.

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 pressures, check the cutting deck's edge distance
from the ground and act on the tie rod (fig. 16, ref. A) and on the adjusting screw (fig. 15, ref. B) if
necessary to put it parallel to the ground. Before acting on the adjusting screw (fig. 15, ref. B), loosen the
corresponding fixing screws (fig. 15, ref. C). If a satisfactory parallel set-up cannot be achieved, contact
an Authorised Service Centre.
HOW TO REMOVE THE CUTTING DEVICE
To remove the cutting device, please follow this procedure:
1) Press the switch (fig. 17, ref. D) until the warning light lights up.
2) Loosen the PTO belt stretcher by turning the corresponding lever (fig. 17, ref. A) and remove the
belt from the cutting deck pulley.
3) Carry out points 1-2-3 listed in the paragraph "CUTTING DECK TILTING".
4) When the cutting deck frame wheels lift from the ground, stop the tilting and put the cutting height
indicator in position "2" (fig. 2, no. 10).
5) Disconnect the connector of the electrical system (fig. 20, ref. A).
6) Lift the red safety hooks (fig. 18, ref. A).
7) Catch the cutting deck frame frontally and remove it from its place.
Attention! Never unlock the switch (fig. 17, ref. D) when the cutting device is off. The cutting deck fixing
arms could violently hit the upper part of the machine with the risk of damaging things or people close to
the machine.
To connect the cutting device back to the machine:
1) Approach the hinges to the hooks by lifting and setting them into their groove.
2) Tighten the red safety hooks (fig. 16, ref. B) and connect the electrical system connector (fig. 20, ref. A).
3) Turn the ignition key into "ON" (without starting the engine). Unlock the switch (fig. 17, ref. D); the
warning light has to be off.
4) Set the PTO belt into the pulley on the deck and tighten it by turning the corresponding lever (fig. 17, ref. A).
5) Lower the mobile foot rest platform (fig. 13, ref. B) and fix the cutting deck with the corresponding red
locking levers (fig. 14, ref. A).
PTO BELT
Attention! This is a special belt, USE ORIGINAL BELTS.
To replace it, loosen the tie rod by acting on the corresponding lever (fig. 17, ref. A) and remove the belt
from the pulley on the cutting deck. Loosen the electromagnetic clutch protection (fig. 21, ref. A) and let it
slide towards the rear part of the machine. In this way it is possible to remove the belt completely from
the electromagnetic clutch.
To set the tension use a no. 13 spanner to turn the nut that adjusts the tension spring (fig. 19, ref. B).
The spring must be compressed to a length of 85 mm.
