7.6 Change of grease in mower elements
Replace the grease in the mower elements every 500 working
hours or every 1,000 hectares.
Follow the directions listed hereafter.
- Remove the mower disc.
- Dismount the bearing housing A (fig. 29) from the element.
Make sure that the shims B remain in place.
Attention! If several bearing housings need to be
dismounted, care should be taken that they are fitted
back on the original mower elements.
- Remove the grease from the element. Do not use a solvent
since it may affect the sealing of the bearings and/or rinse
the grease fill out of the bearings.
- Fill the elements with 95 grams of grease (grease
classification NLGI 0, type calcium-lithium soap or
lithium soap/Shell Alvania WR 0).
Attention! Measure the grease quantity carefully. An
incorrect quantity may cause overheating and damage
of the element.
- Place the bearing housing on the element. Turn the hub C
(fig. 29) so that it is aligned with the hub of the adjacent
mower element (fig. 30).

and tighten them with the following torque of 36 Nm (3,6
kgm) for mower unit with castellated nut.
