Hydrostat transmission

Warning
Risk of injury due to high pressure (up to 5945 psi /
410 bar) in the hydraulic system.
► Check the hydraulic hoses for leaks, damage and chafe
points.
Warning
When oil leaks there is a danger of environmental pollu-
tion.
► Check the hydraulic drive system for leaks before and
after mowing.
Fig. 19:
In warmed up condition, the oil level must be at "MAX" mark-
ing. In cold condition, the oil level must be somewhat below,
in hot condition somewhat above the "MAX" marking.
There always must be oil in the compensation tank so that no
air can enter the hydraulic system.
The oil change must be carried out by an authorized service
centre (see Maintenance table).
Check if the gearbox fan is undamaged.
The hydrostatic drive generates a monotone working noise
that gets louder the more the load is increased (e.g. in steep
terrain). If the working noise changes, if it gets irregular or
very loud, let the hydrostatic drive cool down and check the
oil level.
If the change working noise still exists, have the device
checked by an authorised service centre.
It is possible that the hydraulic system must be ventilated or
the oil must be changed. For refilling, only use the types of oil
specified in the technical data.
