What to do if hydraulic fluid foams in Toro Greensmaster 3120 Lawn Mower?
- Z
  Zachary MaloneAug 22, 2025
  If the hydraulic fluid is foaming excessively and causing leakage from the hydraulic tank breather in your Toro Lawn Mower, several factors could be responsible. First, check if the hydraulic-fluid level in the hydraulic tank is low and refill it to the proper level. Ensure that the hydraulic system uses the correct type of fluid. If not, replace it. Inspect the pump suction lines for any air leaks and repair them. If incompatible hydraulic fluids have been mixed, flush the system and refill it with a compatible fluid. Lastly, check for water in the hydraulic system and drain it.

  If your Toro Lawn Mower's cutting reel motors will not turn, it could be due to several reasons. If your machine does not have a Backlap Mower manifold, the relief valve R1 might be stuck open, requiring repair or replacement. There could be an electrical problem with solenoid valve S1 that needs checking and fixing. The pilot-operated relief valve PRV or pilot piston in the mower manifold may be stuck closed or damaged, requiring repair or replacement. Lastly, the gear pump (P2) might be damaged and in need of inspection and replacement.
