Why my Jacobsen Lawn Mower engine will not start?
- M
  Matthew RossAug 7, 2025
  If your Jacobsen Lawn Mower engine won't start, several factors could be at play. First, ensure the parking brake is engaged, the traction pedal is in neutral, and the mow switch is off, as the interlock system could be preventing ignition. Also, make sure the glow plug has timed out by resetting the ignition switch. Check the battery's condition and connections, and ensure the fuel tank has fresh fuel. Replace the fuel filter and bleed the fuel lines if needed. Finally, inspect the fuse and relays, replacing them if defective. Adjust or replace the neutral switch on the traction pedal if it's out of adjustment or defective.

  If your Jacobsen Lawn Mower engine stops unexpectedly, first check if the fuel tank is empty and, if so, fill it with fresh fuel and bleed the fuel lines. Another possible cause is related to the interlocks; ensure they are properly set before leaving the operator’s seat by engaging the parking brake and setting the mow switch to OFF.

What causes uneven cuts with Jacobsen Lawn Mower reels?
- M
  Mary JacksonAug 31, 2025
  If the reels on your Jacobsen Lawn Mower are cutting unevenly, several adjustments might be needed. Start by inspecting the bedknife-to-reel adjustment. Check the engine speed to ensure it's not too low. Adjust the mow speed to suit the turf conditions. Ensure the mow switch is set for forward rotation. If there's not enough rear roller pressure, move the down pressure spring one hole towards the spring. If the front roller isn't following undulations adequately, move the down pressure spring one hole away from the spring.
