4310 just stops

[greg4x4]

I have a 4310 ehydro and when I am running in low gear at maximum speed and 1/2 to 3/4' s throttle it just stops and will not go again for about a minute, the engine is still running but the tractor will not move. This has only happened twice in about 20 hours of use. Thanks for any help.

Probably checked already, but is trans fluid level okay? Any kinked or bound lines that might restrict flow, cause overheating?

Does you error light flash when this happens? You probably have a sensor out of adjustment. Either a forward or reverse potentiometer or throttle position sensor. Check your manual. It should explain how to count the short and long flashes.

 

[greg4x4]

Yes I did but thanks for thinking of it you never know what people checked or not and some times its that simple

 

[greg4x4]

I didn't think to check if the error light was blinking but I will next time, thanks.

Greg,
is there any chance that the operator is lifting off
the seat enough to have the seat switch trip the
drive module?
I think there is a delay built into that switch,
but if a smaller operator is sitting on the seat, and
they lean a bit forward and the switch thinks
the operator is off the seat, it may do what you
are describing also..
I also think that the light will blink when that happens..

Likely a sensor. think transmission, as throttle you'd hear, and I am almost certain to be fully mechanical.

 

[jd110]

The throttle is fully mechanical but it does have a sensor that sends a signal to the e-hydro controller so it can compensate for speed. If that sensor is out of range, it has no effect on engine speed, but it will default the transmission to neutral, the same as if one of the forward or reverse sensors would.

Thanks, I wasn't aware of that, that definately could factor in this....

I had the following happen to my 4310 shortly after delivery. I don't know if this is exactly the same problem as you are experiencing.

Within 10 to 15 seconds after applying full forward pedal, the machine comes to an abrupt halt as if I had quickly taken my foot off the pedal. Releasing the pedal and then pressing it again results in no forward motion. If I let the tractor sit for 10 to 15 seconds or if I hit the reverse pedal first (it will move in reverse), I regain forward function.

This does not seem to happen at any other pedal position but I can consistently make it happen by pushing the pedal all the way to the end of travel. It happens in any speed range.

At first I did not think there was any code blinked but the blinking happens pretty fast and I had to watch it closely. I don't remember what the code was.

The problem was a bad potentiometer for the forward pedal. It was replaced an I have not had the problem since.

Thank you very much, I' ll check into that.

 

[greg4x4]

I don't think so but I'll watch it.

Thanks

I'm having a similar problem with my 4300. When I'm in the 3rd speed range I lose power and speed as i press down on forward pedal causing engine to almost die. Other 2 speed ranges work ok. I'm still troubleshooting.

Can someone tell me about the potentiometer and where it is located????

 

[jd110]

The 4300 did not have any electronics on the hydro. everything is mechanical. It sounds as if you have a fuel problem unless you are overloading engine. What are you doing when you lose power in third range? This range is primarily a transport speed. If you are trying to cut grass or pull a load, you should probably be in second or first range.

 

[rockyridgefarm]

Sam, what you describe sounds almost normal. If I turn off LoadMatch on the 4310, I can bog down the engine in 'C' with the pedal mashed down.

Of course, you realize that the harder that you press the pedal, the higher the gear, which causes more engine loading. It isn't a gas pedal, but it sure is easy to 'forget' and treat it like one.

Thanks for your comments. I’m fully aware about 3rd range being for transport. I always operate in 1st(low) range when using implements. This problem I'm having occurred right after I cleaned my 4300 inside and out with water and some mild soap.

I'm leaning toward a rear end brake problem. If I tap the brake levers back a little under the rear end the tractor runs normal for about 50 yards. Then I start losing rpms and it feels like something (brakes) slowly starts holding the tractor back as I start losing power dramatically. The rpm gage takes a deep dive. When I let off the pedal rpms rapidly build back up but same thing happens when I press hydro pedal again. Reverse seems to work normal in all ranges.

This happens even going down a steep hill on a paved road. This is totally not normal for this tractor, as I have used it numerous times. I'm at a loss for the cause of this problem.

oh - you CLEANED it! What were you thinking?!!!

I heve the service manual, lemme know if you have a question...
