Erratic reel speed can be caused by a cutting unit problem, a leaking or damaged hydraulic manifold reel circuit cartridge, or a plugged hydraulic manifold orifice.
Why is the hydraulic fluid foaming in my Toro Lawn Mower?
The hydraulic fluid in your Toro Lawn Mower may be foaming because the oil level in the reservoir is low, the hydraulic system has the wrong type of oil, or one of the pump suction lines has an air leak.
Why are the cutting units on my Toro Greensmaster 3250-D 04383 Lawn Mower lifting slowly?
Several factors can cause the cutting units to lift slowly. These include low engine speed, low reservoir oil level, binding or broken lift cylinder linkage, binding lift cylinder bushings, low charge circuit pressure, a leaking or damaged implement relief valve, a leaking or damaged solenoid valve in the hydraulic manifold, a stuck, leaking, or damaged relief valve, internal leaks in the lift cylinders, a hung-up spool in the steering control valve, or a damaged gear pump.
Why is the hydraulic system on my Toro Lawn Mower operating hot?
The hydraulic system may be operating hot due to several reasons: the oil level in the reservoir is low, or the inlet filter is loose or clogged; the oil is contaminated or too light; the parking brake is applied or the brakes are incorrectly adjusted; the hydrostat bypass valve is open or defective; the oil cooler (if installed) is damaged or plugged; the bypass relief is stuck open or airflow is obstructed; the working load of the machine may require the use of an oil cooler; the charge pressure is low; or the wheel motor(s) or reel motor(s) are worn or damaged; or the traction pump is worn or damaged.
Why is the traction response of my Toro Lawn Mower sluggish?
A sluggish traction response can be caused by very cold hydraulic oil, the parking brake being applied or brakes incorrectly adjusted, a hydrostat bypass valve that is open or defective, low charge pressure, or a worn or damaged traction pump or wheel motor(s).
Why is the reel motor drive pump on my Toro Lawn Mower noisy?
A noisy reel motor drive pump, indicating cavitation, can be due to a low reservoir oil level, a restricted hydraulic pump suction line, or an air leak in the hydraulic pump suction line.
Why is there backlash when turning the steering wheel on my Toro Lawn Mower?
Backlash when turning the steering wheel can be caused by a worn or broken cardan shaft fork in the steering control valve, worn or broken leaf springs in the steering control valve, or worn splines on the steering column.
Why is the steering force insufficient on my Toro Lawn Mower?
Insufficient steering force could be due to low hydraulic flow to the steering control valve or a leaking or damaged steering relief valve (R5).
Why is the reel speed low on my Toro Greensmaster 3250-D 04383 Lawn Mower?
A low reel speed can be caused by a cutting unit problem, a leaking or damaged hydraulic manifold reel circuit cartridge, or excessive internal wear in the reel motor.
Why do the cutting units on my Toro Greensmaster 3250-D 04383 Lawn Mower raise but not stay up?
If the cutting units raise but don't stay up, it may be due to leaks in the hydraulic manifold solenoid valve (S4) or internal leaks in the lift cylinders.
