  If your Ferris Lawn Mower engine starts hard or runs poorly, the fuel mixture might be too rich. Try cleaning the air filter. If you have a carbureted model, check the choke adjustment. For fuel-injected models, consult an authorized dealer. Another potential cause is faulty, fouled, or incorrectly gapped spark plugs. You may need to clean, gap, or replace them, referring to the engine manual for guidance.

  If your Ferris Lawn Mower engine stalls easily when the mower is engaged, the engine speed may be too slow. Set it to full throttle. Alternatively, the ground speed might be too fast, so decrease it. Also, check if the cutting height is set too low and increase it if necessary. Finally, ensure the discharge chute isn't jamming with cut grass; cut grass with the discharge pointing towards the previously cut area.
