Maintenance Recommendation

For many Exmark hydro systems, it is recommended to change hydro oil and hydro filters after the first 250 hours of operation, then every 500 hours after the first service interval. Service may be required more often under severe mowing, high heat, dusty, wet, or heavy-use conditions.

Always follow the maintenance schedule in your Exmark operator’s manual for your exact machine.

Why Replace Your Hydraulic Filter?

A clogged, restricted, or contaminated hydraulic filter can reduce oil flow and increase stress on expensive hydro system components. Replacing the filter during routine service helps reduce the risk of pump damage, wheel motor wear, poor drive response, overheating, and premature hydro system failure.

Genuine OEM Exmark filters are designed to meet Exmark requirements for fit, filtration, sealing, and hydraulic system protection.
