How to Troubleshoot a John Deere 4100 That Will Not Start

Instructions

1. • 1

     Check the fuel tank of the unit. Fill the tractor with fuel if nearly empty. Use diesel fuel, since the 4100 requires diesel as opposed to unleaded.

   • 2

     Lift up the seat of the unit to check that the battery is properly connected.

   • 3

     Lift up the hood of the unit and inspect the fuse. Unscrew it with a wrench. Inspect the body for signs of cracking or rust. Replace the fuse, if necessary, and the spark plug.

     Drain the gasoline from the tank and inspect the fuel filter inside. Replace it if it is full of dirt and debris. Diesel fuel often has bits that are caught by the filter.
