Roy..... ....Is this a test? I flunked mindreading, just ask my ex-wife. See iff'n you can't find some more words to describe yer tractor problem. This great N-Board doesn't charge extra for more words. Buttcha gotta help us out by being more descriptive about your tractor problem. Like everybody sez..... ...respectfully, Dell the ex-mindreader

Think of the folks on this board as doctors specializing in Ford tractors; some of us are GP's, while others are brain surgeons! Regardless of our level of expertise, we all need a basic level of info to better help you. What you have told us tractor Doc's so far is your tractors is not feeling well..... ..not a lot to go on, huh? So, what year tractor, 6v or 12v (if 12v, answer souNder's questions below) how long does it run before it cuts off, does it stop dead or sputter first, and how long does it take to restart. Also, what if anything have you done to it lately (tune-up, changing parts, etc)With that info, you will get some very direct & to the point responses!

Runs one-minute and quits = condenser. Starts up again and quits again.
Runs three- to five-minutes and quits = fuel line screens. Will stumble and not start unless you wait a few or several minutes.
Runs 15-minutes and quits = ignition switch. Will restart or not after some several minutes. It will do it again after lunch.
Runs 40- to 60-minutes and quits = front-mount coil. Needs to cool off for an hour or so.

Most generally.

You didn't give us much to go on.. like front or side mount, 12v or 6v.. and if 12v what coil/resistor combos are you using.

Could be anything from a coil problem.. to a bad ignition switch, to a fuel delivery problem.

Most coil problems are front mountand generally involve the lack of a resistor, and the coil overheats. however even with the correct resistor.. the front mount coils simply are not as robust as we would like them to be.

To test the ignition switch, which also isn't very robust, carry a jumper wire to bypass the switch. if it starts right back up after the stall when you bypass the switch.. you found your problem. One caution... if you do not have the oem 2 terminal ignition switch.. but instead have replaced it with some kind of 'auto' style starter switch.. don't just bumble around and start jumpering at random and run yourself over.. make sure you only jumper the ignition contacts.

Lastly would be fuel delivery. This could be anything from you being out of fuel.. or being low and not having the reserve open.. or the reserve tube is plugged up... or it is a new style bowl with no reserve. Could also be the main screen plugged up, bowl screen, or carb elbow screen.

Could be a stuck float starving the carb for fuel, or even flooding the carb out.

Lastly, it could be a fuel tank vacume problem due to a plugged tank vent. Simply opening the gas cap a crack when the engine goes to die will test that.

Ont he last 3 problems, you may notice that pulling the choke a little helps, due to the extra manifold vacume... In the case of a bad ignition switch or coil, a little choke may even help, due to enrched mix... etc.

Sometimes a coil when going bad will work ok when cold but when it gets hot will not. Let it cool 15 min and it will restart, etc. You didn't say if it does it only when cold, or only hot, etc. Another thought is trash in fuel line or carb. The trash circulates and clogs it up, and after it stops it settles and then it will restart and run for awhile until it clogs again. Could be anywhere in line. Pull line from carb and see if you get good stream, not dribble. Check filter at elbow into carb. First things i'd look for.

Thanks, I'll check the gas flow and coil.

Thanks
