Why is the hydraulic system on my Toro Lawn Mower operating hot?
- A
  Andrea MayerAug 19, 2025
  If the hydraulic system in your Toro Lawn Mower is operating hot, it could be due to several reasons. High transmission pressure from load or brakes, low oil level or a clogged inlet filter, contaminated oil, a damaged or plugged oil cooler, a stuck by-pass relief, a defective hydrostat by-pass valve, low charge pressure, or worn motors. You should reduce the load, ensure brakes are released, refill the oil reservoir, clean/replace the inlet filter, change the oil, inspect and repair/replace the oil cooler, check and free the by-pass relief, inspect and repair/replace the hydrostat by-pass valve, check and adjust charge pressure and inspect/replace worn motors.

Why is the hydraulic fluid foaming in my Toro Lawn Mower?
- D
  Diana AndersonAug 26, 2025
  If the hydraulic fluid in your Toro Lawn Mower is foaming, it could be due to a low oil level in the reservoir, the wrong type of oil in the hydraulic system, an air leak in one of the pump suction lines, incompatible hydraulic oils mixed in the system, or water in the hydraulic system. Refill the oil reservoir to the proper level, replace the hydraulic oil with the correct type, inspect and repair any air leaks in the pump suction lines, drain the hydraulic system and refill with compatible hydraulic oil, or flush the hydraulic system to remove water.

Why is the traction response on my Toro Groundsmaster 3505-D sluggish?

  Trevor ClarkAug 28, 2025
  If the traction response on your Toro Lawn Mower is sluggish, it could be due to several reasons: the hydrostat by-pass valve is open or defective, the brake is not released, the charge pressure is low, or the hydraulic oil is very cold, or the traction pump or wheel motor(s) are worn or damaged. Inspect and repair or replace the hydrostat by-pass valve, ensure that the brake is fully released, check and adjust charge pressure, allow the hydraulic oil to warm up to the appropriate temperature, and inspect and replace worn or damaged traction pump or wheel motor(s).
