What to do if my Toro 31230 Lawn Mower has no traction in either direction?

  Hannah SuarezAug 21, 2025
  If your Toro Lawn Mower has no traction, the oil level in the hydraulic tank may be low. The transmission bypass valves could be open, or the charge pressure might be low. The engine flywheel coupling could be damaged, or the transmission or wheel motor(s) may be worn or damaged. Fill the hydraulic tank to the recommended oil level. Check and repair or replace the bypass valves. Check and correct the charge pressure. Inspect and replace the flywheel coupling. Inspect and repair or replace worn or damaged components.

Why is my Toro 31230 traction response sluggish?
- N
  nicolehernandezAug 23, 2025
  Sluggish traction response in your Toro Lawn Mower could be due to several reasons. The transmission bypass valve(s) may be open or defective, the brake could be dragging or binding, or the hydraulic oil might be very cold. Additionally, the transmission check valve, relief valve, and/or flushing valve could be leaking, the charge pressure could be low, or the transmission or wheel motor(s) might be worn or damaged. Inspect and repair or replace the bypass valve(s). Inspect and repair dragging or binding brakes. Allow hydraulic oil to warm up. Inspect and replace any leaking valves. Check and correct charge pressure. Inspect and repair or replace worn or damaged components.

  Ralph GreenAug 28, 2025
  If the cutting deck blades on your Toro Lawn Mower are turning too slowly, it could be due to a low engine speed. There may be a cutting deck problem. The transmission PTO clutch might be worn or damaged. Increase the engine speed to the recommended level. Inspect and repair or replace the PTO clutch.

Why does my Toro Lawn Mower hydraulic fluid foams excessively?
- C
  Charles AndersonSep 1, 2025
  Excessive foaming of hydraulic fluid in your Toro Lawn Mower, leading to oil leakage, can occur if the oil level in the hydraulic tank is low, or the hydraulic system has the wrong type of oil. It may also happen if one of the pump suction lines has an air leak, incompatible hydraulic oils are mixed in the system, or water is present in the hydraulic system. Fill the hydraulic tank to the recommended oil level. Replace with the correct type of hydraulic oil. Inspect and repair any air leaks in the pump suction lines. Flush the hydraulic system and replace with compatible oils. Drain and replace hydraulic oil to remove any water contamination.

Why is my Toro 31230 Lawn Mower gear pump noisy?
- M
  Michael JohnsonSep 6, 2025
  A noisy gear pump in your Toro Lawn Mower, indicating cavitation, can be due to a low hydraulic tank oil level, very cold hydraulic oil, a restricted suction line, or an air leak in the suction line. Fill the hydraulic tank to the recommended oil level. Allow the hydraulic oil to warm up. Inspect and clear any restrictions in the suction line. Inspect and repair any air leaks in the suction line.
