What to do if my Toro 31200 has no traction in either direction?
- L
  Lauren NormanAug 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 31200 traction response sluggish?
- V
  Valerie GrantAug 25, 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.

What to do if my Toro 31200 is difficult to find neutral?
- V
  Vanessa BellAug 26, 2025
  If finding neutral on your Toro Lawn Mower is difficult, the external control linkage may be misadjusted, disconnected, binding, or damaged. An orifice in the transmission check valve(s) could be plugged, or the transmission itself might be worn or damaged. Adjust, reconnect, or repair the external control linkage. Inspect and clean or replace the transmission check valve. Inspect and repair or replace the transmission.

Why is my Toro 31200 Lawn Mower cutting deck blade(s) turn too slowly?
- A
  Amanda MayerAug 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 31200 hydraulic fluid foams excessively?
- J
  Joshua CraneSep 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 31200 Lawn Mower gear pump noisy?
- R
  Richard HerreraSep 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.

Why does my Toro 31200 cutting deck raises, but will not stay up?
- A
  Andrea FullerSep 13, 2025
  If the cutting deck on your Toro Lawn Mower raises but doesn't stay up, it could be due to the lift cylinder leaking internally, or the solenoid valve in lift control manifold port A leaking. Inspect and replace the lift cylinder if it leaks internally. Inspect and repair or replace the solenoid valve in lift control manifold port A.

What to do if my Toro 31200 wheel motor will not hold load in neutral?
- S
  Shannon HuynhSep 16, 2025
  If the wheel motor on your Toro Lawn Mower won't hold a load in neutral, make up fluid from the charge pump may not be available, or the check valves in the transmission could be damaged. On a 4WD machine, the PD1 or PD2 cartridge in the CrossTraxTM AWD control manifold might be leaking or damaged, the valve plate(s) in the transmission could be worn or damaged, or the cylinder block assembly in the transmission may be worn or damaged. Ensure make up fluid is available from charge pump. Inspect and replace damaged check valves. Check and repair or replace the PD1 or PD2 cartridge. Inspect and replace worn or damaged valve plates. Inspect and repair or replace worn or damaged cylinder block assembly.
