4310 cruise control

[chickenman]

When I engage the cruise control on my 4310 it will run for a few minutes then either slow and stop or just stop.

There are no codes flashing

It just started this, any suggestions?

how do you get to the mfwd sensor?

My 4300 did the same thing so I guess a 4310 is similar? When cruise control is engaged a magnet holds the foot pedal in place. My dealer fixed it under warranty and said the solution was to adjust the magnet. I guess it was loose causing it not to hold the pedal in place? Don't know about the sensor.

I agree it could be the magnet, this is where having a service manual would be invaluable.

Chickenman; On my 4300 the cruise did not work at all when first delivered. The pedal underneath my floorboard where the magnet grabbed hold WAS NOT GRABBING because the pedal was NOT SMOOTH enough to allow good contact. Dealer ground the pedal down a bit and it worked perfectly.
Check and see if your magnet has a smooth surface to grip.

the 4310 ehydro doesn't seem to have a magnet like the 4300, it appears to be all done through the computer

If it is ehydro, then I think you are right. I too assumed it was the non ehydro from the OP. I had the 4300 warranty update on my magnet. Had no problem, but dealer made the switch. For the last 10+ years, the cruise has worked well for me.

Might be a good excuse to get the service tech manual CD. Worthwhile to be able to track down problems, and as well, to fix them.

i have the pdf manual, it shows the general location but not the easiest way to get to it

with my stiff joints I'd rather not have to crawl under the tractor

if I can remove the seat it may be easier for me.

I am interested in knowing how they did it on the eHydro. There still
needs to be some sort of clamp to hold the forward go-pedal in place.
Other tractors I have had use a mechanical clamp. To be controllable
electrically, it seems to me that the 4310 is best served by keeping
the magnetic clamp. It is easy enough to see if you have a magnet, if
you look under the floorboards on the right side. It does require getting
under the tractor, however.

The pedal doesn't stay down on mine. I'm pretty sure it is electronic. I will look in the service manual tonight when I get home. Btw the manual on cd was $75.

the pedals actuate potentiometers which send a signal to the computer that sends a signal to the hydrolic drive pump to increase or decrease the flow of oil

The cruise control is part of the computer, there is no direct mechanical linkage
