Posted in the John Deere forum as well. I recently bought a 7020 for the farm. I'm in the process of getting it in shape to hopefully use this coming spring and fall and have a few questions about it and am hoping someone with experience with these can help me out. First thing is on the throttle lever when you push it all the way to being straight up and down with the steering column without pulling out on the black knob it shuts off the tractor is this how it's supposed to be? On my 4020 that's where idle is and you have to pull out the knob and up to shut it off. Second the tractor will run for about 5 minutes then slowly loose rpms and shut down I know about checking the check ball and return line on the injection pump just wondering if there is anything else it could be before pulling the pump to have it rebuilt? The third thing is when starting it sometimes its starts off the key switch and sometimes you have nothing no grunt or anything when you hit the key and have to jump across the starter terminals to fire it up was wondering if it's the key switch, a relay, or wiring issue? Once it's started if it dies usually you can use the key to restart. The 4th thing is when you press the clutch in after about 20 seconds you no longer have steering, thinking a valve or something is bypassing but not certain. The final thing is the pto constantly runs haven't checked to see if the cable is actually acuating the lever for it or not but how much work could be involved if it's something internal.
Sorry for the long post but hoping to disc in the spring with it and disc, chisel and run a small grain cart in the fall.thanks in advance for any help Smalltimer

Today's Featured Article - Tuning Up Your Tractor: The Battery - by Curtis Von Fange. Buried somewhere beneath the sheetmetal, under the gas tank, or stuffed in front of the radiator is the battery. This elusive and neglected component of the tractor is the hardest to get to when it is dead and in need of a jump. But usually, the storage battery is a storehouse of electrical energy waiting to be released a the flick of a switch.
