  Your Jacobsen Lawn Mower engine might not start due to several reasons. First, the parking brake might be disengaged, the traction pedal might not be in neutral, or the reel/3WD switch might be on; check the operator back-up system and start-up procedure. Second, the battery may be low on charge or defective; inspect the condition of the battery and battery connections. Third, the fuel tank may be empty or the fuel dirty; fill the tank with fresh fuel, change the fuel filter, and bleed the fuel lines. Lastly, a fuse might be blown; replace the fuse.
