Bought a 2005 3320 with ehydro this summer that had sat for about 3 years. It needed a fuel shutoff solenoid to run. They drained fuel and oil, changed filters etc and it runs good. Well it did. I decided I needed to familiarize myself with it so I started bush hogging my farm lane. All good so far once I understood cruise control. Started to run over a concrete block and slammed on the brakes. Got stopped, no problem and went around it. Then I started to mow again and tractor seemed to be dragging. Ok maybe brake is sticking but it keeps going slower and slower. (No codes). Drove it to barn, shut it off and took off bush hog in preparation of trip to repair shop. Decided to just try without mower. It seemed to run ok so I put the mower back on and started to drive it. Got about 300 yards and it just died and would not start. Waited about 5 minutes and it started. I mowed ok for another half hour. I am thinking I need to replace the fuel filter first to see where that takes me. Also noted that it seems to consume a lot, lot more fuel then my old AC 5020 does but the AC is a much smaller tractor. So what do the smart people think my issue is.
