SECTION 6:

 TROUBLESHOOTING

6.1 

Q: How do I prevent an uneven cutting pattern and increase the quality of cut?

6.1  

A: Check tire pressure, check blade sharpness (replace blades or sharpen at least once 
per year or when needed), make sure blades are tightened properly, check spring and belt 
tension, check the underside of the deck to ensure the mower deck is free of grass build-up 
and debris, make sure your machine is at full throttle, and vary your mowing pattern each 
time you cut your grass.

6.2  

Q: What should I do if my mower won’t start?

6.2  

A: Check battery charge and connection (grounds), check your fuel (make sure fuel is less 
than 30 days old and contains no water), make sure your spark plug is in good condition 
and spark plug wire is attached, and make sure air filter is clean (a dirty filter makes it more 
difficult for the engine to draw air). Check the integrity of the 25 amp main fuse; also check 
for any bare wires and/or bad connections.

6.3 

Q: What should I do if the blades won’t engage?

6.3 

A: Make sure the safety switch is plugged in on the bottom of seat. Check the underside 
of the PTO engager to ensure the plug is secure at switch. Also check PTO fuse 
underneath operator console (10amps)

6.4 

Q: What type of fuel is recommended for my mower?

6.4 

A: We recommend that you use a name brand fuel to ensure quality.  Use fuel with an 
octane rating near 87. Higher octane fuels offer no benefit. Only fuels with an ethanol content 
of 10% or less may be used. By law, E-15 fuel is not permitted. Usage of E-15 will result in 
premature engine failure.

6.5 

 

Q: Do you offer touch-up paint for your mowers?

6.5 

 

A: Touch-up paint is available. Contact your local dealer for more information.

Q: 

How do I clean my mower?

6.

6 

 

A: 

It is recommended that you use an air hose or blower to remove dust and 

debris from the mower, to ensure there is not a build up of grass   

on the mower deck and engine compartment, which could become a fire 

hazard. If you must wash the mower, ensure you run the engine to operating 

temp to dry water and engage the blades to spin off any standing water on 

the pulleys. Avoid spraying water onto electrical components and bearings, to 

prevent premature failure of these parts.
