Why is a single cutting unit lifting slowly or not at all on my Toro Reelmaster 5510?

If a single cutting unit lifts slowly or not at all on your Toro Lawn Mower, clean the debris buildup, check and address any binding, and repair or replace damaged components. The issue might be excessive debris buildup on the cutting unit, a binding lift arm or lift cylinder, a stuck or damaged pilot piston in the lift control manifold, internal leaks in the lift cylinder, or a plugged or damaged flow control orifice in the lift control manifold for the affected cutting unit.

If the steering on your Toro Lawn Mower is inoperative or sluggish, there are several things you can check: worn or binding steering components (inspect and repair), a binding steering cylinder (inspect and fix), a low fluid level in the hydraulic reservoir (fill to the appropriate level), a stuck or damaged steering relief valve (inspect and repair or replace), internal leaks in the steering cylinder (inspect and repair), a worn or damaged steering control valve (inspect and repair or replace), or a worn or damaged gear pump section (inspect and repair or replace).

What to do if my Toro Reelmaster 5510 wheel motor does not turn?

Bradley LongAug 28, 2025
If the wheel motor on your Toro Lawn Mower doesn't turn, consider these potential causes: The brakes might be binding, so inspect and fix them. Alternatively, the piston (traction) pump bypass valve could be open, so check, repair, or replace it. Lastly, the piston (traction) pump or the wheel motor itself might be worn or damaged; in this case, inspect and repair or replace the affected components.

What to do if my Toro Lawn Mower hydraulic fluid foams excessively?
C
Christy HarrisAug 28, 2025
If the hydraulic fluid in your Toro Lawn Mower is foaming excessively, causing leakage from the hydraulic tank breather, consider the following: The hydraulic fluid level in the hydraulic tank may be low, so fill it to the proper level. The hydraulic system might contain the wrong type of fluid, in which case you should replace it with the correct type. There could be an air leak in one of the pump suction lines, so inspect and repair any leaks. Incompatible hydraulic fluids might be mixed in the system; drain and replace the hydraulic fluid to resolve this. Finally, there might be water in the hydraulic system, so drain and replace with dry hydraulic fluid.

Why is a single cutting unit lowering very slowly or not at all on my Toro Reelmaster 5510 Lawn Mower?

If a single cutting unit lowers very slowly or not at all on your Toro Lawn Mower, inspect for binding issues, replace damaged components, and clear or repair flow control orifices. This could be due to a binding lift arm or lift cylinder, a damaged lift cylinder, a plugged or damaged flow control orifice in the lift control manifold for the affected cutting unit, or a stuck or damaged check valve in the lift control manifold.

Why won't the wheel motors hold a load when the traction pedal is in neutral on my Toro Reelmaster 5510 Lawn Mower?

Rachel MartinezSep 23, 2025
If the wheel motors on your Toro Lawn Mower will not hold a load when the traction pedal is in neutral, check the charge pressure and replace or repair the valve plate and/or piston shoes. This could be due to low charge pressure or scored valve plate and/or piston shoes in the piston pump.

Why won't the rear cutting unit motors operate on my Toro Reelmaster 5510, but the front ones will?

If the rear cutting unit motors on your Toro Lawn Mower will not operate but the front cutting unit motors will operate, test and replace solenoid valve MSV1 if necessary, ensure the mow/backlap lever is fully rotated, and check for electrical issues. This problem may occur if solenoid valve MSV1 on the mow control manifold is faulty, the mow/backlap lever for the rear cutting units (MR1) is not rotated fully, an electrical problem exists that prevents the MSV1 solenoid coil from being energized, the rear cutting reel(s) is binding, or gear pump section (P1) is worn or damaged.

What causes one or more cutting unit does not stay up on my Toro Reelmaster 5510 Lawn Mower?
Q
qescobarSep 5, 2025
If one or more cutting units on your Toro Lawn Mower raises but doesn't stay up, it could be due to: leaking lift circuit hydraulic lines or fittings (inspect and repair), air in the lift circuit (bleed the air), a lift cylinder for the affected cutting reel(s) that leaks internally (inspect and repair), a leaking check valve in the lift control manifold (CV1, CV4, CV5, and CV23) (inspect and repair or replace), or a stuck or damaged pilot piston in the lift control manifold (inspect and repair or replace).

ortizshawnSep 3, 2025
If one cutting reel on your Toro Lawn Mower raises slowly or not at all, consider these potential causes: excessive unwanted elements on the cutting reel (remove them), a binding lift arm or lift cylinder (inspect and fix), a stuck or damaged pilot piston in the lift control manifold (inspect and repair or replace), a plugged, stuck, or damaged flow control orifice in the lift control manifold for the affected cutting reel (inspect and clean or replace), or a lift cylinder that leaks internally (inspect and repair).
