If none of the cutting units on your Toro Lawn Mower will raise or lower, here are some things to check: Ensure the fluid level in the hydraulic reservoir is at the appropriate level. Make sure MR1/MV1 and/or MR2/MV2 in the lift control manifold are not in the backlap position; if they are, position them out of it. If an electrical problem exists that prevents the SVRV solenoid coil on the lift control manifold from being energized, refer to electrical troubleshooting to fix the energization issue. Inspect and repair or replace the damaged solenoid valve SVRV in the lift control manifold, if necessary. Finally, inspect and repair or replace the gear pump section (P4) if it is worn or damaged.

What causes the cutting reel motor to not operate on my Toro Reelmaster 5510?

Lindsey DodsonAug 31, 2025
If a single cutting reel motor on your Toro Lawn Mower does not operate, rotates slowly, or stops under load, several factors could be at play: the relief valve in the mow control manifold might be bypassing (inspect and repair), the traction speed and cutting conditions may exceed cutting unit capacity (adjust conditions or reduce speed), the cross-over relief valve in the cutting reel motor could be stuck or damaged (inspect and repair or replace), the cutting reel motor itself may be worn or damaged (inspect and repair or replace), the cutting reel motor may have internal leakage (inspect and repair or replace), or the gear pump section (P2 or P3) might be worn or damaged (inspect and repair or replace).

If a single-wheel motor on your Toro Lawn Mower turns when unloaded but slows down or stops when a load is applied, it could be due to the piston (traction) pump bypass valve being open or leaking (check and repair or replace the bypass valve), or the wheel motor being worn or damaged (inspect and repair or replace the wheel motor).

Why is it difficult to find neutral on my Toro Reelmaster 5510 Lawn Mower?

If you're having trouble finding neutral on your Toro Lawn Mower, or if it only operates in one direction, it could be due to: incorrectly adjusted, disconnected, binding, or damaged traction control linkage (adjust or repair the linkage), a check relief valve in the piston (traction) pump that is not seating or is damaged (inspect and repair or replace the check relief valve), or a worn or damaged piston (traction) pump (inspect and repair or replace the piston pump).

What to do if my Toro Lawn Mower hydraulic fluid foams excessively?

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.

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 Reelmaster 5510 Lawn Mower steering is inoperative?

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).
