Why Jonsered YT46 will not start?
- V
  Veronica RussellAug 20, 2025
  Your Jonsered Tractor might not start due to several reasons: it could be out of fuel, the engine might not be choked properly, or the engine could be flooded. Other potential causes include a bad spark plug, a dirty air filter, a dirty fuel filter, or water in the fuel. Also, check for loose or damaged wiring. If none of these resolve the issue, the engine valves may be out of adjustment, requiring you to contact an authorized service center. Remember to fill the fuel tank, replace the spark plug or fuel filter, clean/replace the air filter, and check all wiring.

Why Jonsered YT46 Tractor engine will not turn over?
- P
  Paula Rogers DDSAug 27, 2025
  If the engine of your Jonsered Tractor won't turn over, make sure the brake pedal is depressed and the attachment clutch is disengaged. A weak or dead battery, a blown fuse, or corroded battery terminals could also be the cause. Check for loose or damaged wiring, a faulty ignition switch, or a faulty solenoid or starter. If the problem persists, there may be an issue with the operator presence switch(es), requiring you to contact an authorized service center. Depress the brake pedal, disengage the attachment clutch, recharge or replace the battery, replace the fuse, clean the battery terminals, check/replace the ignition switch or solenoid/starter.

  An uneven cut with your Jonsered Tractor can be caused by a worn, bent, or loose blade, a mower deck that isn't level, a buildup of grass, leaves, or trash under the mower, a bent blade mandrel, or clogged mower deck vent holes. Replace the blade and tighten the blade bolt, level the mower deck, clean the underside of the mower housing, replace the blade mandrel and clean around mandrels to open vent holes.
