I have a 4310 E Hydro and I can't seem to get the hand throttle to hold where I put it.
I've adjusted it 3 different times, it works for awhile than it'll float back down while running and loose RPM's.

The service manual that I have doesn't give a good brake down of this part, does anyone know if there is something that wears out in this area?

Learn how to use JDparts;):thumbsup:

Most common problem is one or both friction disks (#2) are cracked or distorted.

Thanks, that explains a lot, where do I find JD parts you speak of?

A trip to the dealer in the morning is in order.

It the same basic parts system the dealer uses at the parts counter, and it's FREE to register! Another benefit of buying green;)

Just remember to "think like a parts guy"

Well replaced both the friction washers, spring washer, and a new lock nut.
Working great for now, hopefully it stays that way.

It should...for a while anyway. Where the old ones cracked?

No cracks, just hardened a bit.
I think the problem was actually the lock nut not holding.
