John Deere 4310 stalling

[Jalps]

I have a John Deere 4310 diesel 4wd with 230 hours that I recently bought. After about 45 minutes running, the tractor stalls. It has no problem restarting but when I press the gas, it stalls again. I replaced the fuel filter and air filters and tried it again several days later and same thing. After about 45 minutes of use, it stalls. Any thoughts would be greatly appreciated! I am considering just taking it into the shop but thought I would try here first.

Welcome to the forum.

Just to try to help, what does "press on the gas" mean? Do you have the hydrostatic transmission with the forward reverse pedals on the right-side floor? Or do you have the gear transmission with an accelerator on the right-side floor?
If so, do you have the stall problem when 'pressing' one of those pedals?
Have you experienced the same 'stalling' of the engine when the gear selector is in A (low) and B (medium) speed?

Hope we can help solve your problem. /forums/images/graemlins/grin.gif

Is your tractor power-reverser or ehydro?

Does it die completely? or just bog down but still idle?

How long has this been happening? What have you done to the tractor since this started happening? Have you put fuel in it? Any water in fuel? Has it been sitting for a long period nearly empty of fuel? This can cause condensation in the tank.

Also, check the little switch under the seat. This is in effect while PTO is engaged. It can shut off the tractor if no circuit is completed.

The tractor has the hydrostatic transmission and yes, when I push on the forward pedal on the right side of the tractor, the engine stalls. I have tried the tractor in A, B & C, and the stalling is consistent in any gear. Thanks for your help!!!

When I bought the tractor, the tank was full, so I am not sure of water in the fuel. I guess I could have that tested or just drain the tank and refuel with new diesel fuel. The engine does bog down and if I don't let off the pedal, it stalls. I have only had the tractor a week, so I have only used it about 4 hours but it is consistent when I use it 30 to 40 minutes, it starts to stall. I don't know about the PTO switch under the seat. If it helps, there is an hour glass symbol that flashes to the left of the hour display and I don't know what this it. Thanks for your help!

I think you need to have the transmission checked out, as it is acting like there is a problem with the hydrostatic.

The e-hydro (if you have it) may be out of adjustment or set wrong, but it should not stall in all gears. A mechanic (Deere) said the e-hydro's are pretty free of problems, although the early ones had to have some computers reset due to some early problem. But I don't know what the symptoms were of those problems. Let's hope it is a simple adjustment or something. /forums/images/graemlins/wink.gif

Hopefully this wasn't a problem before you bought the tractor used, and it makes a good deal not so good. /forums/images/graemlins/frown.gif

Thank you very much for your response. The tractor does have an e hydro. I will have this checked out and hope that it is nothing expensive to fix. Your right, this may make this not a very good deal but I remain hopeful! Again, I appreciate the time you have given to me!

Check out the fuel tank make-up air vent hose- it usually comes off the top of the tank and then goes down. Insects have been known to make nests in them and after the tractor runs awhile a vacunm is created. Cracking the cap would correct it. Crud floating around in the tank can do gremlin like things especially when the tank is low. /forums/images/graemlins/crazy.gif

I have not checked that but certainly will. It does seem to be a fuel supply issue but I am open to all suggestions. The fuel tank was almost full when I encountered the problem so it was puzzling to me that it ran so well for about 45 minutes and then the engine sputtered before dying. Thank you very much for taking the time to help me!

From these statements- You have just bought the tractor and have put about 4 hours on it. I notice that you say that if you let off the pedal is ceases to stall. A hydro is set up to where if you let up on the pedal it is similar to going to a lower gear. You have more power the farther the pedal is let up. Could it be that as you are starting to do heavier work that you are not letting the pedal up to compensate for it?

 

[Jalps]

Jerry, thank you for responding. I can tell you the first time I used it I was using the bush hog, so I tried it again without using any implements and still the same problem.

Just to the left of your steering column is the LoadMatch switch. With it on, it should be almost impossible to stall the engine, as the computer will adjust the hydrostatic automatically to keep from lugging. If it stalls with LoadMatch engaged, you really do need to get it adjusted...

here is a Link to the 4310 Owners Manual. If you don't have one, you could prit that out, or refer to it online.

What RPM are you trying to use the tractor at when it stalls?

Remember, the pedal is NOT the gas pedal, just because you push it down doesn't mean you are going to go faster. It needs a corresponding amount of RPM. It will tend to "bog" in gear "C" unless the throttle is about 2200 RPM or more. Only use C for going fast, not for any working conditions.

I think the fellow above hit the nail on the head, your tank might be vacuum locked. I doubt very much you have any tranny problems.

I think the seat switch is good place to start. Are you certain the switch is being depressed?
If there were problems with the hydro, you may see the service light blinking on the right fender.. It blinks in a pattern that indicates certain problems depending on what is wrong with the transmission. Also, is there any chance that some wires under the tractor near the hydro pedals were pulled on while you were bushhogging? If these connections become loose or come apart, the tractor may not move at all. (not sure if it would stall though)
I think you can test the seat switch by sitting in the seat, and pulling up on the PTO switch and see if it comes on. (you don't need an implement on to try this). If the PTO comes on, stand up and see if it kicks it off.

Have you been able to start the tractor at first and drive it cold consistently? Then, once it warms up it acts up? Or is this more of a problem all the time now?

One more place to look, is there any chance the brake is stuck on? Some of these linkages stuck in the on position, and need a good swift kick in the pedal to get them unstuck.

Let us know what you find out.
good luck

Oh, 1 more thing,
Are you sure your Hydrostatic Fluid level is up where it needs to be?
you check that at the rear of the tractor next to the PTO,, ther is a sight glass.. on level ground with 3ph down see if you see the hydro fluid in the glass.. it should be full so you can see the fluid level in the glass. I'm sure with your hours the fluid won't be quite as clear as when new... it's almost reddish from the factory if it hasn't been changed at the recommended service.

My 4300 was doing the same thing when I when over a bump. My weight would come up off of the seat and the safety circuit would kill the engine just as if I had fallen off of a moving tractor. If your foot is on the go pedal-the tractor must have the seat switch depressed or it will cut the engine. Sounds like your problem is in the seat switch circuit. Pat

My 4300 kept stalling on my wife when she drove it. Realized she had not moved the seat forward and when she pressed the Go pedal she had to get off the seat a bit. Moved the seat: Problem solved.

Thanks for all the suggestions for a fix to my problem. I took it to the John Deere place and the problem turned out to be a defective fuel injector pump. Just thought I would let everyone know that this is not an uncommon problem with the 4310 and 4410 per the mechanic at the dealership.

Thanks for the feedback. Glad you have the problem solved.

<font color="green"> ...turned out to be a defective fuel injector pump... ...this is not an uncommon problem with the 4310 and 4410 per the mechanic at the dealership </font>

Wow! Uncommon?!! I have never heard a single complaint about an injector pump...(not that I know anything...) But then, that's why there are warranties...

Glad its fixed!!!

I just tre-read your first post, and it does seem like an injector pump...
