Why is the hydraulic system on my Toro Groundsmaster 4700-D running hot?
- DDebra PerezJul 25, 2025
If the hydraulic system in your Toro Lawn Mower is operating hot, several factors could be the cause. First, ensure the engine RPM is not too low and increase it if necessary. Check and refill the hydraulic reservoir oil level if it's low. The hydraulic oil may be contaminated or the wrong type, in which case you should change it to the correct type. Also, verify that the brakes are not engaged or sticking; release or repair them if they are. Inspect and repair the piston pump by-pass valve if it's open or damaged. Ensure the cooling system is operating properly, and check and correct the charge pressure if it's low. Adjust the traction circuit pressure if it's incorrect. Finally, inspect and repair or replace any damaged pumps or motors.
