Why is the hydraulic system on my Toro 03676 operating hot?
- B
  Brandon FisherSep 7, 2025
  If the hydraulic system on your Toro Lawn Mower is operating hot, stop the machine, turn off the engine, and locate the cause of the trouble and correct it. This could be due to high traction system pressure, low oil level in the hydraulic reservoir, contaminated or light hydraulic oil, low engine speed, a damaged or plugged oil cooler, obstructed airflow through the oil cooler, a plugged oil filter, low charge pressure, or an open or faulty piston pump bypass valve.

What causes one cutting reel lowers very slowly on my Toro Lawn Mower?
- E
  Eric ThompsonSep 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).

What causes one or more cutting unit does not stay up on my Toro 03676 Lawn Mower?
- K
  Karla WolfeSep 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 the steering wheel to turn the Toro Lawn Mower in the wrong direction?

  If turning the steering wheel on your Toro Lawn Mower causes the machine to move in the wrong direction, the hoses to the steering cylinder are likely reversed. Correct the hose connections to the steering cylinder to resolve this issue.

  Jason DeckerSep 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).

Why won't the wheel motor hold load in neutral position on my Toro 03676 Lawn Mower?
- F
  Frederick HawkinsSep 2, 2025
  If the wheel motor on your Toro Lawn Mower does not hold a load in the NEUTRAL position, it could be due to: low charge pressure (check the charge pressure and make adjustments as necessary), damaged check valves in the piston (traction) pump (inspect and repair or replace the damaged check valves), a worn or damaged valve plate(s) in the piston (traction) pump (inspect and repair or replace the worn or damaged valve plate(s)), or a worn or damaged wheel motor (inspect and repair or replace the wheel motor).

What to do if none of the cutting units will raise or lower on my Toro 03676?
- M
  Michelle WalkerSep 1, 2025
  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 03676 Lawn Mower?
- S
  Steven McleanAug 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).

Why does single-wheel motor turns slowly on my Toro 03676?
- K
  Kimberly HortonAug 30, 2025
  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 Lawn Mower?
- A
  Alice ValdezAug 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).
