How to Adjust Hydrostatic Cable on John Deere F525
The deck of the John Deere F525 mower is located at the front of the vehicle. Its hydrostatic transmission uses hydraulics to drive the mower, rather than belts and gears. Inside the transmission is a hydraulic motor and pump; the transmission generates pressure and pushes fluid to the engine, which turns the wheels. The only cable that periodically needs adjusting is the speed-control cable. After you access the cable, it is not difficult to adjust; however, you will need to remove some components to gain access to it. Does this Spark an idea?

Tips & Warnings
Moving the control levers forward 1 inch determines whether the transmission cable needs adjustment.
If the drive wheel turns when you push the control lever forward after locking it in position, the cable requires adjustment.
Always work on the John Deere F525 in a well ventilated area. Even with the engine off, exhaust fumes can make you sick.
Do not work under the mower without the F525 being supported off the ground and secured in place.
