Transmission Maintenance

Oil Change
Most homeowners with gardens do not have the tools or experience needed to change the transmission oil.
The transmission probably has a longer life than the rider itself, which means that being able to change the
oil is not of major concern to the average consumer. The lifespan of the transmission increases, however, if
the oil is changed.
If the rider is used commercially, we recommend changing the oil first after 50 hours of use and then every
500 hours or at least once per year.
IMPORTANT INFORMATION
Used oil is an environmental hazard
and must not be disposed of on the
ground or in nature; it should always
be disposed of at a workshop or
appropriate disposal location.
Avoid skin contact; wash with soap and
water in case of spills.
The K66 hydrostatic transmission
The transmission holds 2.5 litres (2.6 US qt).
(SAE 10W/30 engine oil, class CD–CF).
The hydrostatic transmission filter and
hydraulic filter should be changed when oil
changes are performed.

hole.

tank from the hydrostatic transmission.

through the fill hole. Replace the hose
and fill the oil tank.
