Cub Cadet How to Check Hydraulic Fluid on Your Zero Turn Mower

Checking Hydraulic Oil

Check the oil level of hydraulic units only when the engine is OFF.

During initial break-in (first five hours of operation), check oil before each use and after every hour of operation.

During normal operation, check oil after 50 hours of operation.

•Flip seat up and clean the area around the hydraulic oil dipstick to prevent debris from entering the crankcase. See Figure 15.

•Remove the hydraulic fill plug/dipstick and read the

level:

If hydraulic oil level is inside operating range, then do nothing.

If hydraulic oil level is below operating range, the add hydraulic oil before operating. Also check for leaks.

If hydraulic oil level is above operating range, then drain excess oil before operating.

•Reinstall the dipstick completely into the fill tube.
