Why does the engine not stop when the ignition key is rotated to the Off position on my Toro 04351?
- A
  Alison PatelSep 12, 2025
  If the engine does not stop when the ignition key is rotated to the Off position, the ignition switch connection may be loose, the ignition switch could be damaged, the wires in the connector might have shorted, or the engine timing or carburetor adjustment may be incorrect. Push the connector onto the ignition switch terminals, replace the ignition switch, repair the affected wires, or adjust the carburetor or engine timing.

- D
  David CurtisSep 10, 2025
  If there is no #1 or reverse traction speed in the hydraulic system and the #2 speed is normal, the disc seal between the #3 and #4 valve sections may be damaged or missing, the poppet inside the #4 spool could be stuck open or off its seat, the traction relief cartridge in the #4 spool section might be open, a traction motor may lack efficiency, or the hydraulic pump could lack efficiency. Remove the valve bank and replace the disc seal, repair the #4 spool section, or repair or replace the relief cartridge. Test to identify the faulty motor and repair or replace it.

Why is there no ground speed increase in the #2 selection on my Toro Lawn Mower?
- K
  Kevin FosterSep 9, 2025
  If there is no ground speed increase in the #2 selection, the control lever may be misadjusted, the rear camshaft could be misadjusted, the mow/lift linkage might be binding, there could be wrong detent parts in the #4 spool, or the #2 or #3 spool relief valves may be stuck open. Adjust the control lever, adjust the camshaft by moving the right end or the rear camshaft forward or the left end rearward, lubricate or repair the machine, remove the valve bank and repair the #4 spool assembly, or remove and repair or replace the relief cartridge.

  If your Toro Lawn Mower engine won't start, there are several things to check. First, the fuel tank might be empty, so fill it up. The ignition system could be faulty, requiring repair. Also, the starter system may be malfunctioning; inspect the connections, solenoid, starter motor, and ignition switch. Finally, check the carburetor fuel solenoid, including its wiring.

  If your Toro Lawn Mower's hydraulic system has no #1 or reverse traction speed, but #2 speed is normal, it could be due to a damaged or missing disc seal between the #3 and #4 valve sections; remove the valve bank and replace the disc seal. Another possibility is that the poppet inside the #4 spool is stuck open or off its seat; in this case, remove the valve bank and repair the #4 spool section.

How to fix slow cutting unit lift on Toro Lawn Mower?
- M
  Michael LeSep 5, 2025
  If the cutting units on your Toro Lawn Mower lift too slowly, it could be because the rear camshaft is misadjusted; adjust the camshaft. The #1 spool travel may be restricted by the mow/lift switch, so adjust the switch. Alternatively, the lift check poppet in the #1 spool section might be stuck partially closed; remove the lift check and repair or replace it.

Why is there no traction on my Toro Lawn Mower?
- A
  Alexandra PhillipsSep 4, 2025
  If there is no traction or it is slow in all selections on your Toro Lawn Mower, consider the following potential causes: The brakes may be dragging, so determine the cause and repair it. The o-ring seals around the traction relief cartridge or inlet sleeve in the #4 spool valve may be faulty, causing fluid leakage; in this case, replace the o-rings after removing the relief and inlet sleeve. A traction motor(s) might be worn or weak, requiring testing, repair, or replacement. The pump could be excessively worn, so test to verify and then repair or replace it. Finally, the traction relief in the #4 spool valve may be open; remove, repair, or replace it.

- C
  Christopher BlakeSep 3, 2025
  If the engine of your Toro Lawn Mower fails to crank no matter the position of the shift selector or mow pedal, several issues could be at fault. The battery terminals might be corroded, so clean them. The mow/lift switch, traction switch, and/or seat switch may be adjusted incorrectly or damaged. The mow/lift or traction switch wires could be loose. The battery might be dead, requiring a charge or replacement. A solenoid or the ignition switch could be damaged, necessitating replacement. The starter may be damaged, needing replacement or repair. The engine could be seized, requiring engine repair. The key switch, voltmeter, or solenoid wires might be loose, so connect them. Finally, ensure the operator is on the seat.

Why are all three cutting units raising and lowering too slowly on my Toro 04351?

  If all three cutting units raise and lower too slowly, the lift cylinder and linkages may be binding due to lack of lubrication. Lubricate more frequently.
