7.3 Periodic maintenance
Periodic maintenance must be carried out:
• at the start of the mowing season;
• before prolonged storage of the machine;
• when the machine is used extensively during the season.
- Grease all points of the machine listed in § 7.2 “Lubrication”.
- Grease the spring-loaded locking pins of the yoke lock of the PTO
shaft.
- Check if the PTO shafts telescope smoothly.
A damaged PTO shaft may cause excessive wear and tear to the
machine and tractor.
- Check the V-belts for correct tension.
To do so, open the V-belt housing. The tension should be such that
each V-belt can be pushed in (fig. 20), between the pulleys,
approx. 10 mm by applying a force of 70 N (7 kg).
It is advisable to depressurise the V-belts if the machine will not be
used for a long period of time.
- Check the condition of the wear plates, mower discs and knives.
(Replacement of knives: see § 7.4).
- Check the knife pins for tightness (fig. 21).
The clip must be properly locked by the cam of the mowing disc.
- Check the mower discs for tightness (fig. 21). The castellated nut
torque is 150-250 Nm (15-25 kgm). The split pin locking the
castellated nut may not protrude above the pressure piece.
N.B. the nut may not be turned back; keep turning it until the split
pin can be fitted.
- Check the machine for any damage and flaws.
- Check the gearbox for any oil leaks.
(Changing oil: see § 7.5.)
