2005 GX345 - Keeps rolling when I let off pedal

When I am mowing I need to literally hit the brakes or plan my stop because the tractor keeps rolling after I let off the pedal. I do not think this is normal, does any know what might cause it?

Thank you I will look into that.

I don't know if it is rates but the release rod at the back of the tractor does not release the trans so it freewheels either.

Is the release rod still attached to the lever that's goes down into the transmission? Has it broke off or unattached?

Sounds like you may have a linkage issue but if it is your shock, read the second to last post in this thread before you buy one https://www.mytractorforum.com/12-jo...en-cold-2.html

Id also check the linkage first with what we know about the freewheeling bar.

That said, the $30 shock is compelling enough that you should buy one as Im wondering if a previous owner may have messed with the linkage thinking abrupt stopping was caused by something there rather than the shock (and they may not have wanted to spend the money on the Deere shock).

Re: 2005 GX345 - Keeps rolling when I let off pedal

You always question the prices at a John Deere dealer on their parts. Also, any sub-website selling John Deere parts. J. Deere probably has a secret selling plan to all that sells their parts, that 'no one" is to sell a part lower than such price what Deere has set forth.

As denverguy mentioned, you have to question where there is a "exact" part someone is selling that will work. A big difference is $140.00 for Deere part and $38.95 another lawn tractor part will work.

The difference is one is in a JD box and the other directly from the manufacturer that supplies it per JDs spec. It could also be counterfeit, but even if thats the case, it seems plenty of people have had good luck with it. For $100 savings, its worth the gamble.

Re: 2005 GX345 - Keeps rolling when I let off pedal

I found this interesting because I've had this with my K66 (very similiar to your K71/K72). A simple problem with a little time.

This sounds like the problem "creeps in neutral".

If when you experience the creep, you apply some reverse pedal input just to see if it stops and then stays stopped, then this is an indicator of creep. (you are manually returning the control lever to neutral)

When you start the tractor, if you have not applied control, will it stay, or creep?

Have you lost power in one or both directions? If no, its most likely creep.

Three categories that can cause creep,

1) Speed control linkage, bent, or obstructed by built up debris.

2) The actual lever on the transaxle or roll pin being loose or damaged, play.

3) Internal failure of the transaxle.

Of these three, the first one is most common and one that I have had. Even a bad nylon bushing can contribute to creep, or grass clippings built up around the control arm.

The PDF is Tuff Torq's Trouble Shooting Guide to their transaxles.

Because your chassis is a very strong chassis, I doubt you have any flex or horizontal torsion from front to back when on extreme uneven terrain, so ruling this out as a culprit to common grass cutter chassis's, I would look from your pedals to the control rod, to the transaxle for anything that is damaged, loose, alignment issues, or binding on the return of the control rod. I believe you will find your answer there.

You can rule out the shock by disconnecting it, just for the purpose of ruling it out. The shock was designed to dampen the response from motion to stop. (customer concerns on a stopping jolt or abrupt harsh stop caused the addition of the shock according to Tuff Torq)

I hope this helps.

Excellent info!

I haven't noticed creep at a stop I will do some test driving and see what I find.

Thank you for the very informative reply!

Re: 2005 GX345 - Keeps rolling when I let off pedal

I've had several pedal-operated JD's with similar issues. I took some WD 40 with the red tube on it and squirted it in all of the places that the linkage went through while working the pedals. That cured everyone that I had with the no stop problem. The sudden stop issue is just a bad shock and either live with it or buy a replacement.

try lubricating your pedals , under the tractor where the bushings are
