How Often Should You Change the Hydro Fluid of a Cub Cadet?

Cub Cadet riding lawnmowers use a hydrostatic transmission to help propel the mower. The transmission uses hydrostatic fluid, which requires replacement at regular intervals to maintain normal operation.

Fluid

New Cub Cadet tractors require a hydrostatic fluid change after the first 10 hours of use. A second change is required after 50 hours of use. After the second hydrostatic fluid change, you should replace the fluid every 100 hours of use. Keeping a notebook in the same area that you store your lawnmower can help you keep track of this.

Filter

Hydrostatic transmissions on Cub Cadet tractors have a filter that removes impurities from the fluid and keeps them from entering and damaging the transmission. Dirty filters are less effective at removing impurities from the fluid. Change the hydrostatic filter when you change the fluid to ensure the peak performance of the transmission.

Considerations

Some Cub Cadet models, such as the 1046 VT, were designed with a self-contained hydrostatic transmission. This type of transmission is sealed and does not have a hydrostatic fluid fill or drain plug. Have your Cub Cadet tractor serviced by a trained technician if you experience problems with the hydrostatic transmission.

Change The Hydro Fluid Of A Cub Cadet?

Cub Cadet has been manufacturing riding mowers since 1961, and their engine and transmission systems have evolved over the years. Because the transmission system has changed over the years, it's important to consult the manual for your specific model for information on swapping out the hydro fluid. This is why it's essential to check the transmission fluid level periodically. Most contemporary full-size riding mowers have sealed systems, but the manual for the ZT1 42 instructs the user to check the transmission fluid after each 200 service hours and to add more, or change it if necessary. As a rule of thumb, a complete replacement of the hydro fluid in any tractor or mower model without a sealed system should occur after 1,200 service hours. Using the manual as a guide, locate the drain plug for the transmission system. Replace the main hydraulic filter; then refill the reservoir with the appropriate hydraulic fluid. Most systems are self-priming, so after you complete the procedure, start up the engine and let it idle for 30 seconds or so to purge air.
