Why are all the reels on my Toro GREENSMASTER 3100 Lawn Mower running slowly or not turning?
- C
  Christine ForbesAug 14, 2025
  If all reels on your Toro Lawn Mower are running slowly or not turning at all, start by checking the engine RPM and adjust it using a tachometer. Also, ensure the hydraulic oil level is correct. A clogged hydraulic filter can also cause this issue, so inspect and replace it if necessary. Inspect the linkage and roll pin on the end of the mow pedal shaft for any damage and repair if needed. Finally, inspect the reel pump flow and repair or replace the pump if necessary.

  Kelly OliverAug 18, 2025
  If your Toro Lawn Mower has a slow ground speed in all traction selections, begin by checking the engine tachometer RPM for improper adjustment. Also, check the hydraulic oil level to ensure it is properly filled. A clogged hydraulic filter could also be the cause. Other potential issues include traction motor efficiency, shift lever adjustment, binding brakes, traction pump flow, traction relief, and mechanical drag in the traction motors. Inspect and repair or replace defective components as needed.

  If one or more cutting units on your Toro Lawn Mower have slow or no reel drive action, check the pedal linkage for misadjustment; adjust, repair, and lubricate as needed. Also, inspect the rearward valve spool travel and adjust the rear camshaft if there is insufficient travel. Check for tight bedknife adjustment and adjust accordingly. Other potential causes include tight bearings, reel pump flow, reel motor flow, reel drive relief, and reel motor efficiency. Replace reel bearings if necessary, and repair or replace other defective components.

Why does the center cutting unit operate in the raised position on my Toro Lawn Mower?

  If the center (#1) cutting unit on your Toro Lawn Mower operates in the raised position, check the rear camshaft for the #3 spool being too far out of the body. Also, check for restrictions in the brazed tube assembly on the #3 valve section and remove any restrictions. Finally, check for any restrictions in the valve return port between the #3 section and the R.H. cover; remove the valve bank to inspect.
