To check the oil level, ensure the mower is on a level surface. Remove the oil fill plug from the gearbox and check if the oil is at the recommended level. If not, add oil until it reaches the correct level.
Use SAE 90 weight gear oil for optimal performance and longevity of the gearbox.
It is recommended to change the gearbox oil every 500 hours of operation or annually, whichever comes first.
Common signs include unusual noises, difficulty in shifting, oil leaks, and reduced mower performance. If you notice any of these, inspect the gearbox.
Inspect the seals and gasket for damage. Check the oil level and condition. Replace any worn or damaged seals to stop the leak.
Basic maintenance like oil changes can be done by the owner. For repairs involving internal components, it is advisable to consult a professional technician.
Stop using the mower immediately to prevent further damage. Inspect the gearbox for worn gears or bearings and replace them as necessary.
Ensure that the gearbox is properly sealed and the oil is at the correct level. Store the mower in a dry place and perform regular maintenance checks.
Basic tools include a wrench set, oil drain pan, oil fill pump, and appropriate oil for refilling.
The serial number is typically located on a label on the gearbox housing. Refer to your user manual for the exact location.
