That's not a bad idea actually. Let's say the battery is bad and the marginal voltage is causing trouble. You might want to get a meter and check it.

My advice is to take the battery out and move it 50 ft or so from your tractor so that you won't be tempted to try and just boost it off. Put another known good battery in its place and see how it runs. I just knew I had a major problem the way the tractor acted, but it was nothing but the battery.
The easiest thing to do with the battery is check the voltage. Lead/acid batteries have 2.2 volts per cell times six or 13.4 volts. Figure that for a good charged battery. Anything over 12.5 volts should not give you problems.
The type of problem he's having could be cause by a marginal battery that is, say, 11.5 volts but batteries as a rule do not go intermittent. That is, they drop in voltage but never go to zero volts and then back to 12 volts.
The first place to start is checking the solenoid to see if it is falling off. It's easy and will help us hone in on the trouble. The way to trouble shoot is to keep eliminating different areas where the problem can be. This is a how trouble shooting goes whether you're looking for a bad board in a mainframe computer that takes up two buildings or a toaster.
I remember once troubleshooting a massive radar system that had been intermittently failing for two years driving the Navy nuts. No one could find it because they kept guessing. It wasn't that they didn't know electronics, they were wizzes, they had poor trouble shooting skills. You pedantically eliminate each section until you get to the problem.

If that were my situation I'd tell them to keep it and give me another tractor, or I will be seeing you in court. They should at least give you a loaner in the meantime.
Diagnostics won't find a loose connection that only opens when the tractor is moving.
Let's say it's a sensor that tells the main computer to shutdown the engine and the wire from the sensor only opens sporadically when you're moving, they'll never find it sitting in the shop.

That may be 100% correct, but we spend a lot of money on these tractors, more than many brand new cars. It is not reasonable to expect this guy to sit and wait around for weeks or months until they figure it out. I understand that all manufacturers make a lemon now and then, but JD or the dealer should step up and make it right.
Just my two cents.

I agree completely, at this price I'd be asking for another tractor or at the least a master tech from Deere meeting me at the dealer.
There's lots of things they could do even if they are poor trouble shooters. Start with switching out the main computer. I wouldn't take no for an answer at this point.

My 4520 would do it every morning I would turn the key to off wait a second then start and be fine all day, then it did it one morning and wouldn't start. t long story short there is a ground wire by the starter and the shield was over the terminal I cut it back and resanded the metal to clean it and no more problems
Different problems, his is not a turn over or starting problem it is an intermittent cut off problem.

Got my 3320 back home yesterday. I have run it about 8 hours without a cut off. JD replaced every thing about the fuel system. New fuel lines,filters,shut off solenoid, and a new fuel pump. So far so good. I have it on trial and catching up on jobs needing to be done. I plan on using every day this week all day.
This is truly a fine machine and I hope it is fixed. Thanks for all your comments.

Speaking for all of us 3320 owners.....I'm glad JD stepped-up for you and (apparently) fixed the problems you were having. One of the reasons to buy a good brand IMO. Great news....GOOD LUCK!!! :thumbsup: Keep us posted!

Great news, I hope she's bulletproof from here on out! :thumbsup:
you should be able to tell if the engine runs out of fuel, or if it shuts down hard, like from the key switch. If it shuts down hard, you may have a bad fuel solenoid, which is easily changed. when you key on, you should hear a sharp CLICK when the fuel turns on. If it's kind of a muffled noise, or if you ever have to key on several times to get the CLICK then almost certainly the solenoid is bad. Diesels that run lean on fuel usually run weak for a few seconds and then die.

mddozier I hope this dealership wasnt near me ,what part of the country are you in? How many times did it take them to verify your complaint as that is one of the first steps in diagnosing . would love to know what the problem realy was. glad they finaly fixed it for you. Also the fuel solenod linkage is all internal so visualy checking is not an option.

This same shut off problem happened to my son and I last week while clearing brush with his JD 3320E. The tractor ran ;for a few feet and then stopped. It would start right up again but only run less than a minute or two before shutting off again.
Since the property was extremely dry and dusty I thought about cleaning the air filter as the possible problem (actually got a real bad burn from the muffler doing this). Once this was done the tractor started but shut off again. Igt was then that I noticed that the fuel turn off lever on the fuel pump was almost turned to the off position and the fuel bulb was totally distended and almost totally distorted. (Iguess from pressure built up over time used)
Unless we had a one in a million hit from a pranch or something that pushed the lever to the off position, it must have been the vibration from using the tractor all day.
This has never happened before and didn't happen after we fully turned on the fuel supply.
I hope we don't have your problem and length of down time.
