The cutting unit bevel gear

Check the oil level
Check the oil level when the cutting deck is in its lowest
position.
• Insert a clean metal rod (approx. Ø3 mm) through the filler
plug. Lower the rod until it reaches the bottom of the gear
housing (approx. 90 mm).
• Pull up the metal rod and read off the oil level. The oil level
must be between 18-22 mm from the end of the rod.
• Fill with transmission fluid SAE 80W/90 as necessary.
CAUTION! Too high an oil level increases the risk of oil
leakage.
Changing the oil
• Empty the bevel gear through the filler plug using a pump
fitted with a plastic tube that extends to the bottom of the
housing.
Alternative: Remove the cutting unit and plastic covers.
Place the cutting unit on its edge and empty the bevel gear
through the plug.
• Fill the bevel gear with 80 ml of transmission fluid SAE
80W/90
