5.13 ADJUSTING THE MAIN BELT TENSION
The flywheel V belts must be checked for tension and condition. If any belt shows sign of
wear, surface damage, shredding, excessive glazing, or have been stretched to their
limit, they must be replaced.
Multiple belt drives must have all belt drives replaced at the same time. Belts that are too
loose will cause poor cutting performance, excessive belt and pulley wear.
To check the main belt tension and adjust it if required, do the following:
1. Stop the engine.
2. Remove the ignition key and put it in a safe place.
3. Open the bonnet.
4. Locate the main belt tensioner (1, Figure 70).
Figure 70 - Main belt tensioner
5. For the main belts, check the belt tension. The deflection should be the width of
one belt.
