Why won't my Simplicity Lawn Mower engine turn over?

  Kyle DonovanAug 20, 2025
  If your Simplicity Lawn Mower's engine won't turn over, make sure you are sitting in the seat and that the brake pedal is fully depressed. Ensure the PTO (electric clutch) switch is in the OFF position and that the cruise control is disengaged (lever in Neutral). Check if the circuit breaker has tripped, waiting a minute for an automatic reset, or replacing it if necessary. If these steps don't work, the battery terminals may need cleaning (refer to the Battery Maintenance Section), or the battery might be discharged or dead, requiring a recharge or replacement. For faulty solenoids, starter motors, or safety interlock switches, consult your dealer.

  If your Simplicity Lawn Mower engine turns over but doesn't start, first, disengage the choke if the engine is flooded. Check the spark plugs; they might be faulty, fouled, or incorrectly gapped, requiring cleaning, gapping, or replacement. Also, the fuel could be old or contain water; in this case, drain the fuel tank, refill it with fresh fuel, and replace the fuel filter. For a faulty safety interlock switch, consult your dealer.

  If your Simplicity Lawn Mower engine starts hard or runs poorly, the fuel mixture might be too rich. Try cleaning the air filter and checking the choke adjustment. Also, inspect the spark plugs; if they are faulty, fouled, or incorrectly gapped, clean, gap, or replace them.

What to do if Simplicity Lawn Mower engine stalls easily with mower engaged?

  Amanda AustinAug 26, 2025
  If your Simplicity Lawn Mower engine stalls easily when the mower is engaged, ensure the engine speed is set to full throttle and that you are not moving too fast. If the cutting height is set too low, especially in tall grass, raise it to the maximum height for the first pass. Make sure the discharge chute isn't jamming with cut grass by directing the discharge towards the previously cut area. Allow the engine to warm up for several minutes before engaging the mower, and avoid starting the mower in tall grass. For carburetor issues, refer to the Engine Manual.

  If the drive belt on your Simplicity Lawn Mower is slipping, check if the pulleys or belt are greasy or oily and clean them if necessary. If the belt is stretched or worn, replace it with a new one. Also, inspect the idler pulley pivot bracket; if it's frozen in the declutched position, remove it, clean, and lubricate it.

  If your Simplicity Lawn Mower is vibrating excessively, check if the blade mounting screws are loose and tighten them to 45-55 ft.lbs. (61-75 N.m.). Inspect the mower blades, arbors, or pulleys for any bending and replace if necessary. Also, make sure the mower blades are balanced, replacing them if they are not. Finally, ensure the belt is installed correctly.

  If your Simplicity Lawn Mower engine runs but the tractor won't drive, ensure the ground speed control pedals are depressed and that the transmission release lever is in the drive position, not the “push” position. Also, check if the parking brake is engaged and disengage it. For a broken drive belt, see Drive Belt Replacement. If the drive belt slips, see cause and remedy below.
