John Deere 4200 4WD Hydro will not start, please help me out!!! I was doing some backhoe work and was on a slight incline, went to drive tractor forward and it stalled out. Checked fuel and it was low and with the incline could have ran out. (not sure) it didn`t sputter at all, just when I gave it gas to move forward it died suddenly. Filled it up and now I cannot get it to start. Towed it about 10 ft so that it is now sitting on level ground. I sprayed a real small amout of starting fluid in air intake and it ran for a couple seconds, I`m sure just on the starting fluid, seems like its not getting fuel. Drained fuel bowl, tried pumping the manual pump but still nothing, checked all fuses, can someone please help me out!!!
