6.3.10 STEERING MAINTENANCE
Regularly check to see that there is no excessive play between the steering rack and pinion.
If there is too much play, reduce it.
Ignoring this maintenance can cause damage to the steering.
How to adjust the play:
Open the hood of the machine.

Loosen the two M12 nuts (1) on the eccentric bolt.

On the hexagonal eccentric (2) place an appropriate wrench and turn it until the the play

is reduced to the minimum.
Tighten both M12 nuts (1) to 35 - 45 Nm.

6.3.11 CHECKING AND ADJUSTING THE DRIVE BELT

through or even produce an odour, it is necessary to tension or replace it.
Take off the mowing deck cover (

By tightening the nuts on the bolt, set the spring to a length of 55 ± 1 mm.

Do not over-tension the belt above this level, this will reduce its lifetime and may
also cause damage to the transmission!
Reattach the mowing mechanism cover.

6.3.12 BELT REPLACEMENT
Replacing the drive belt is a relatively demanding procedure and must be entrusted to an authorized
service facility.
6.3.13 REPLACING WHEELS
Before changing one of the wheels, park the tractor on a solid, level surface, shut off the engine and
remove the key from the ignition. Change the wheel as follows:
Raise the machine using an appropriate jack on the side on which the wheel is to be

changed. Set the jack below a solid part of the machine's frame or on the transmission
arm. Secure the machine below with an appropriate wooden block.
Remove the protective cover from the wheel (front wheels only).

Use an appropriate screwdriver to remove the retaining ring and remove the washer.

Take the wheel off the shaft. For rear wheels there is a spring on the shaft.

When putting the wheel back on, perform the assembly steps in reverse order. Before installing the
wheel, clean all parts, and lightly grease the shaft. Especially for wheels on the rear axle, this greasing
is indispensable for later wheel removal. If the shaft is not greased, later assembly may be
difficult.
When installing a rear wheel, be careful of the mutual position of the spring on the shaft and the groove
in the wheel.
6.3.14 REPAIRING TYRE DEFECTS
The machine is equipped with tubeless tyres. If they are defective, entrust their repair to a professional
tyre service or to an authorized Seco lawn mower service centre.
