4300 Hydro Stuck in low! - Competition Diesel.Com

Well Crapola!

I lent my trusty JD 4300 Hydro compact to my in-laws. They called and said after they unhooked the PTO from hay elevator it would not move. So I drive over to see. Yup they are right.

In range C (high range) and range B ( mid range) you push the go pedals it just grones and stalls. Range A (low range) it works just fine other than the 4mph wound tight top speed!

Long ride home! I think when you put in C or B it is in both and this is causing the trouble. Basicly like a trans brake. I see no problems with any external linkage. I just last month changed all the filters and fluids. Deere fluids and Wix filters.

Anyone have this problem before? Any ideas how to fix? I have not called the dealer yet. This really stinks as we use this little bugger more than all the other tractors we own. This is the busiest time off year for it.

Broken shifter fork?? What is the pattern. Years ago I broke a fork on a truck. It had one gear that was ok, but if you went to a few others it did what you said.

Broken roll pin in side on the selector shaft. Easy fix other than having to pull the whole side off.
