I am needing some help with my tractor. Last year after I finished disking my food plot my tractor started running rough (it was very dusty). It would rev up then act like it would die then rev up and act like it would die with smoke (not dark) coming out the tailpipe. When I got it back to the barn I shut it off and tried to start again but it wouldnt start. It would turn over but wouldnt start. I cleaned the air filter and replaced the 2 fuel filters. I started up but continued to run rough. Eventually (weeks later) it started running normal again. Well, I started disking this past weekend and got about 3 laps in and it started doing the same thing. Im not too familiar with working with tractors but I am mechanically inclined and would like to fix this myself. Does anyone know what the problem could be? Any help would be appreciated.
