Why is the hydraulic system on my Toro Lawn Mower operating hot?
- V
  Victoria JacksonNov 21, 2025
  If the hydraulic system in your Toro Lawn Mower operates hot, it could be due to several reasons: The engine RPM might be too low, the brakes could be applied or sticking, the hydraulic reservoir oil level might be low, the hydraulic oil could be contaminated or the wrong type, the piston pump by-pass valve could be open or damaged, the cooling system may not be working correctly, the charge pressure could be low, the traction circuit pressure might be incorrect, or the pumps or motors could be damaged. To resolve this, try increasing the engine RPM, releasing or fixing the brakes, checking the hydraulic reservoir oil level, replacing the hydraulic oil if it's contaminated or incorrect, checking the piston pump by-pass valve, ensuring the cooling system is working, checking the charge pres...

Why is the steering on my Toro Lawn Mower inoperative?
- J
  Justin BrownAug 25, 2025
  If the steering on your Toro Lawn Mower is inoperative or sluggish, it could be caused by worn or binding steering components (like tie rods or steering cylinder ends), a binding steering cylinder, a low oil level in the hydraulic reservoir, a stuck or damaged steering relief valve in the steering control valve, internal leaks in the steering cylinder, a worn or damaged steering control valve, or a worn or damaged gear pump section. Inspect and repair or replace any worn or binding steering components. Maintain the correct hydraulic oil level. Repair or replace the steering relief valve if it's stuck or damaged. Inspect the steering cylinder, control valve, and gear pump section for any damage.

Why is hydraulic oil foaming in my Toro 30447N Lawn Mower reservoir?
- M
  Maria SummersAug 26, 2025
  If hydraulic oil in the reservoir of your Toro Lawn Mower foams, it could be due to a low hydraulic reservoir oil level, the wrong type of oil in the hydraulic system, or air leaking into a pump suction line. Maintain the proper hydraulic reservoir oil level, use the correct type of hydraulic oil, and check for air leaks in the pump suction line.

  herrerataraAug 27, 2025
  If the cutting deck or wing decks on your Toro Lawn Mower raise but won't stay up, check for leaking lift circuit lines or fittings, damage to the lift cylinder, or damaged seals or faults in the cartridge valve(s) in the lift/lower manifold. Repair or replace any leaking lines or fittings, inspect the lift cylinder for damage, and repair or replace any faulty cartridge valve(s) with damaged seals.

Why does my Toro Lawn Mower cutting deck section stop under load?
- E
  Elizabeth SheltonAug 29, 2025
  If the cutting deck section on your Toro Lawn Mower stops under load, it could be because the relief valve in the PTO manifold for the affected deck is by-passing, the deck motor has internal leakage (by-passing oil), or the cutting deck gear pump section is worn or damaged. Repair or replace the relief valve, inspect the deck motor for internal leakage, and check the cutting deck gear pump section for wear or damage.

Why will cutting deck not raise on my Toro 30447N?
- M
  Miss Rhonda CraigSep 23, 2025
  If the cutting deck (or wing decks) on your Toro Lawn Mower will not raise, it could be due to several reasons: the engine RPM is too low; the hydraulic oil level in the reservoir is low; the solenoid valve (S1) in the lift/lower manifold is faulty; there is an electrical problem; the lift arm pivots are binding; the relief valve in the lift/lower manifold is stuck; the lift cylinder(s) is (are) damaged; or the gear pump section for the lift/lower circuit is inefficient. Increase the engine RPM, maintain the correct hydraulic oil level, repair or replace the faulty solenoid valve, troubleshoot the electrical system, free up any binding lift arm pivots, repair or replace the stuck relief valve, inspect the lift cylinder(s) for damage, and check the gear pump section for efficiency.

Why does cooling fan always rotates at fast speed on my Toro 30447N Lawn Mower?
- K
  Katherine TurnerSep 18, 2025
  If the cooling fan on your Toro Lawn Mower always rotates at fast speed, it could be due to a faulty fan control manifold proportional relief valve (PRV) or an electrical problem preventing the fan control manifold proportional relief valve (PRV) from operating. Repair or replace the faulty PRV and troubleshoot the electrical system.

Why will low speed (4WD) not engage on my Toro 30447N Lawn Mower?
- K
  kimberlydunnSep 8, 2025
  If the low speed (4WD) on your Toro Lawn Mower will not engage, it could be due to an electrical problem, a faulty solenoid valve (SV) in the 4WD manifold, faulty cartridge valve(s) in the 4WD manifold, a loose or damaged drive gear on the rear axle motor or driven gear for the rear axle, or a damaged rear axle motor. Troubleshoot the electrical system, replace the faulty solenoid valve, repair or replace the cartridge valve(s), ensure the drive gear is secure, and inspect the rear axle motor.

Why does cooling fan always rotates at slow speed on my Toro Lawn Mower?
- R
  Robert MorganSep 5, 2025
  If the cooling fan on your Toro Lawn Mower always rotates at a slow speed, the fan control manifold cartridge valve seals may be leaking, the check valve in the fan control manifold may not be seating properly, the fan control manifold proportional relief valve (PRV) may be stuck open, or the hydraulic fan motor may be worn or damaged. Repair or replace any leaking seals, ensure the check valve seats correctly, repair or replace the stuck PRV, and inspect the hydraulic fan motor for damage.
