Why my Jacobsen HR 9016 Turbo Lawn Mower engine will not start?
- RryanknappAug 13, 2025
If your Jacobsen Lawn Mower's engine won't start, possible causes include a disengaged parking brake, the power take-off switch being ON. You should check the Interlock System and start-up procedure. Other potential issues are a glow plug that hasn't timed out (reset the ignition switch), a low or defective battery (inspect its condition and connections), an empty or dirty fuel tank (fill with fresh fuel, change the fuel filter, and bleed the fuel lines), a blown fuse (replace it), defective relay(s) (test and replace the relay), the traction pedal not in Neutral (check pedal position and adjust the linkage), a malfunctioning neutral switch on the drive pump (test, adjust, or replace the switch), or a faulty forward sensing switch on the drive pump (test, adjust, or replace the switch).
