Why won't the wheel motor hold load in neutral on my Toro 04470 Lawn Mower?
If the wheel motor on your Toro Lawn Mower will not hold load in neutral, the make up fluid from the charge pump may not be available, or the piston pump relief valves could be leaking or damaged. Ensure the charge pump is providing make up fluid and inspect the piston pump relief valves for leaks or damage.
What to do if my Toro 04470 has no traction in either direction?
If you have no traction in either direction with your Toro Lawn Mower, the cause may be binding or incorrectly adjusted brakes. The oil level in the reservoir could be low. The piston pump by-pass valve might be open or defective. Also, the charge pressure could be low, or the piston (traction) pump or wheel motor(s) may be worn or damaged. You should adjust the brakes, refill the oil to the correct level in the reservoir, inspect the piston pump by-pass valve, and test the charge pressure. Finally, check the condition of the piston (traction) pump and wheel motors.
Why is the hydraulic fluid foaming in my Toro 04470?
If the hydraulic fluid in your Toro Lawn Mower is foaming, it could be due to a low oil level in the reservoir. It is also possible that the hydraulic system has the wrong type of oil or that there is an air leak in the pump suction line. Check the oil level in the reservoir and refill as needed. Ensure that the correct type of oil is used. Inspect the pump suction line for leaks and repair them.
Why is neutral difficult to find on my Toro 04470 Lawn Mower, or why does it only operate in one direction?
If you are having difficulty finding neutral or your Toro Lawn Mower only operates in one direction, the external traction control linkage might be misadjusted, disconnected, binding, or damaged. Another potential cause is a worn or damaged piston (traction) pump. Adjust or repair the external traction control linkage and inspect the piston (traction) pump, replacing it if necessary.
Why is the steering wheel on my Toro 04470 hard to turn?
If the steering wheel on your Toro Lawn Mower is hard to turn, it could be due to insufficient oil flow to the steering valve or a missing or damaged emergency steering ball in the steering valve. Check the oil flow to the steering valve and repair any issues. Inspect the emergency steering ball for its condition.
Why is the steering force insufficient on my Toro 04470 Lawn Mower?
If the steering force on your Toro Lawn Mower is insufficient (possibly to one side only), the hydraulic flow to the power steering may be low, or the implement relief valve in the steering valve might be leaking or damaged. Check the hydraulic flow to the power steering and address any deficiencies. Inspect the implement relief valve for leaks or damage.
Why is the reel speed low on my Toro Lawn Mower?
If the reel speed on your Toro Lawn Mower is low, there may be a cutting unit problem, the hydraulic manifold reel circuit cartridge could be leaking or damaged, or there might be excessive internal wear in the reel motor. Inspect the cutting unit for issues, check the hydraulic manifold reel circuit cartridge for leaks or damage, and test the reel motor for wear.
Why does the rear wheel shimmy when I turn the steering wheel on my Toro 04470?
If the rear wheel shimmies when the steering wheel is turned on your Toro Lawn Mower, there may be air in the steering cylinder, or the mechanical connections to the wheel or wheel bearing may be worn. Bleed the air from the steering cylinder and inspect mechanical connections to the wheel and wheel bearing for wear.
Why is the steering response on my Toro Lawn Mower too slow when turning quickly?
If the steering response on your Toro Lawn Mower is too slow and heavy when trying to turn quickly, the oil supply to the steering valve may be insufficient. Check the oil supply to the steering valve and repair any issues.
Why are the reels not turning on my Toro 04470?
If the reels on your Toro Lawn Mower will not turn, the solenoid valve S1R1 may be stuck open or damaged. There could be an electrical problem, the FC1 logic valve in the control manifold might be stuck open, the PRV valve in the control manifold could be stuck closed, the pilot piston in the control manifold may be stuck or damaged, or the front section of the gear pump might be worn or damaged. Inspect and test the solenoid valve S1R1 and replace or repair as needed. Check for electrical issues and inspect the control manifold and valves for proper operation.
