•Slowly turn the axle anti-clockwise until the drive shafts start to rotate forwards.

•Slowly turn the axle clockwise until the drive shafts stop rotating forwards and make a mark on the transmission housing (FS) and the axle.

•Turn the axle clockwise 8° from the mark on the transmission housing.

Transmission maintenance

Oil change

Most garden owners do not have tools for or experience of changing transmission oil. The transmission probably has a longer operational life than other ride-on mower components, this makes transmission oil changes less important for most customers. However, the transmission's operational life is increased if oil changes are made.

If the ride-on mower is used professionally, it is recommended to change the oil firstly after 50 hours use and every 300 hours use thereafter.

The transmission K 46 has a capacity for 2.2 litres/ 2,35 USqt (SAE10W/30 engine oil, grade SF-CC).

The oil does not need changing in a manual gearbox.
