Troubleshooting
!
WARNING: Always disengage the blade, turn off the engine and remove the spark plug
wire before servicing your machine.
Please refer to the Engine Manufacturer's Owner's Manual for specific engine maintenance
and troubleshooting information.
Belts
The belt frays or rolls over the pulley Þ A pulley groove may be nicked. Check the belt
for wear and hard spots. File off any nicks on the
pulley.
Þ The belt may be stretched. Replace it.
Blade
The cut material is not being properly discharged out
of the right side of the machine Þ The discharge may be blocked. Disengage the
blade, turn off the engine, disconnect the spark
plug and check for debris.
Heavier growth gets hung up under machine and
does not discharge Þ Try removing the baffle under the front of the
mowing deck.
The blade is not cutting or is loose Þ The blade may not be seated properly. Loosen
the blade nut, reset the blade and tighten the nut.
Differential
Differential locks when not in engaged position Þ Follow the adjustment instructions on page 18.
Engine
Recoil will not pull out or is difficult to pull. (Briggs &
Stratton Engine, Models ATM10S and ATM10E only) Þ Check that the blade lever is in the disengaged
position.
Þ The recoil may be broken or jammed. Try to turn
the engine pulley by hand, with the spark plug
wire off. If it turns, the recoil is broken or
jammed.
Engine won't start Þ Check for adequate, fresh fuel.
Þ Check that the fuel valve is turned on.
Þ Check the fuel filter to see if it is clear. Remove
the line from the engine side of the filter. If gas
flows freely, it’s OK.
Þ Check the throttle adjustment and travel.
Þ Is the blade engagement lever down
(disengaged)? It should be.
Þ Check the spark plug.
Þ Tecumseh and Kawasaki engines have a 10 amp
fuse on the wiring harness. Check the fuse and
replace if needed.
Electric-Starting Models:
Þ Check the wire connections—especially the
ground connection, the large green wire coming
from the battery where it connects to the engine.
