What causes one cutting reel lowers very slowly on my Toro 03681 Lawn Mower?
- C
  Clinton RussellSep 6, 2025
  If one cutting reel on your Toro Lawn Mower lowers very slowly or not at all, it could be due to: a binding lift arm or lift cylinder for the affected cutting reel (inspect and fix), a damaged lift cylinder for the affected cutting reel (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 stuck or damaged check valve in the lift control manifold (CV1, CV4, CV5, and CV23) (inspect and repair or replace).

- D
  David SteeleAug 27, 2025
  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 03681 Lawn Mower wheel motor does not turn?
- S
  Stephanie DiazAug 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?
- B
  billy13Aug 29, 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 it difficult to find neutral on my Toro 03681 Lawn Mower?
- A
  Amber ParsonsAug 30, 2025
  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).

Why won't the front cutting unit motors operate on my Toro Lawn Mower, but the rear ones will?
- Z

  If the front cutting unit motors on your Toro Lawn Mower will not operate but the rear cutting unit motors will operate, test and replace solenoid valve MSV2 if necessary, ensure the mow/backlap lever is fully rotated, and check for electrical issues. This issue may arise if solenoid valve MSV2 on the mow control manifold is faulty, the mow/backlap lever for the front cutting units (MR2) is not rotated fully, an electrical problem exists that prevents the MSV2 solenoid coil on the mow control manifold from being energized, the front cutting reel(s) is binding, or gear pump section (P2) is worn or damaged.

What to do if the cutting units raise but will not remain in the raised position on my Toro 03681?
- S
  Stephen BrewerSep 12, 2025
  If the cutting units on your Toro Lawn Mower raise, but will not remain in the raised position, inspect and repair the lift cylinder and check valves. This can happen if the lift cylinder leaks internally, the check valve in the lift control manifold (CV1, CV4, CV5 and CV23) and solenoid valve (SV1 and SV3) leaks, or the pilot piston in the lift control manifold is stuck and is preventing the check valve from seating.

What causes one or more cutting unit does not stay up on my Toro 03681 Lawn Mower?
- S
  Shaun BerrySep 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).

What causes one cutting reel raises slowly on my Toro 03681 Lawn Mower?
- V
  Veronica QuinnSep 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).
