Why will low speed (4WD) not disengage on my Toro Lawn Mower?
If the low speed (4WD) on your Toro Lawn Mower won't disengage, it could be due to an electrical problem, a faulty solenoid valve (SV) in the 4WD hydraulic manifold, or a damaged or sticking cartridge valve in the 4WD manifold. Troubleshoot the electrical system, repair or replace the faulty solenoid valve, and inspect the cartridge valve for damage or sticking.
Why will low speed (4WD) not engage on my Toro Lawn Mower?
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 is the traction pedal on my Toro Lawn Mower sluggish?
If the traction pedal on your Toro Lawn Mower feels sluggish, it could be due to a stuck or binding traction control linkage, low charge pressure, plugged or damaged piston (traction) pump servo control valve orifices, or leaking or damaged 4WD manifold PD1 and PD2 pilot directional valves seals. Free up or repair the traction control linkage, check the charge pressure, clean or replace the piston pump servo control valve orifices, and inspect the 4WD manifold valves and seals.
Why does cooling fan always rotates at slow speed on my Toro Lawn Mower?
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.
What to do if my Toro Groundsmaster 4100-D Lawn Mower operates in one direction only?

Why do all cutting deck sections operate slowly on my Toro Lawn Mower?
If all the cutting deck sections on your Toro Lawn Mower operate slowly, it could be due to a low engine RPM or damage to the deck motor or gear pump sections. Increase the engine RPM and inspect the deck motor or gear pump sections for damage.
Why won't the cutting deck on my Toro Groundsmaster 4100-D lower?
If the cutting deck (or wing decks) on your Toro Lawn Mower won't lower, it could be because the lift arm pivots are binding, there's an electrical problem, the solenoid valve (S1) in the lift/lower manifold is faulty, the counterbalance pressure is excessive, or the lift cylinder is damaged. Free up any binding lift arm pivots, troubleshoot the electrical system, repair or replace the faulty solenoid valve, check the counterbalance pressure, and inspect the lift cylinder for damage.
Why does my Toro Lawn Mower cutting deck section stop under load?
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.
What to do if cutting deck on my Toro Groundsmaster 4100-D won't stay up?
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.
