6.3.12 CHECKING AND ADJUSTING THE TRAVEL DRIVE BELT
Regularly check the tension of the travel drive belt. The belt is correctly tensioned when a force of 4 kPa acting on the
middle distance between the belt pulleys (1) and (3) results in the belt bending by approximately 1.5 cm.
When the amount of deflection increases, it is necessary to adjust the tension.
Positions in the picture are:
(1) Engine belt pulley
6.3.12a
(2) Guide belt pulley
(3) Tensioning belt pulley
(4) Transmission belt pulley
To measure force you can use a standard mechanical dynamometer available in stores selling such products.
Adjust the tension of the belt by tightening nut (6) so that the spring (5) is stretched to a length of 95±1 mm.
6.3.12b
Do not over-tension the belt above this level, this will reduce its lifetime and may also cause damage to the transmission!
6.3.13 REPLACING BELTS
Replacing the drive belts is a relatively demanding operation, which needs to performed by an authorised service centre.
6.3.14 REPLACING WHEELS
Before replacing one of the wheels, park the mower on a horizontal and rigid surface, turn off the engine and remove the key from
the ignition. Perform the replacement as follows:
► Lift the mower using an appropriate jack on the side where you will perform the replacement. Locate the jack under
a solid part of the frame or under the arm of the transmission. Using a wooden block, secure the mower to prevent it
rolling off.
6.3.14
► Remove the protective cover (1) from the wheel (only the front wheels).
► Using a suitable screwdriver remove the retaining ring (2) and remove the washer (3).
When reattaching the wheel proceed in the reverse sequence to its removal. Before attaching the wheel clean all parts and lightly
grease the shaft with a plastic lubricant. Especially for wheels on the rear axle this lubrication is essential for the subsequent
removal of the wheel. In the event that lubrication is not performed the subsequent attachment may be very difficult.
When attaching the rear wheel pay attention to the mutual alignment of the pin on the shaft and the groove on the wheel.
6.3.15 REPAIRING A TYRE PUNCTURE
The mower is equipped with tubeless tyres. In the event of a puncture, have it repaired at a specialised tyre repair shop or at an
authorised deealer.
6.3.16 MAINTENANCE OF THE HYDROSTATIC TRANSMISSION
For the reliable operation of the transmission it is necessary to maintain the correct oil level. The filling openings on the transmissions
are accessible after taking the ejection chute off the mower (
