Last fall I wrote about a 656 hydro I had just purchased. I was having a problem with it coasting or at least not being held back descending hills like I think it should. I was told to check the snap ring on the end of the shuttle valve, which I did, but it was intact and looked fine. I then broke my leg and got laid up for quite a while and didn’t get any further with it.
I’ve been using it this spring and still seem to have the same problem. There seems to be no problem climbing hills or pulling. Even used it to plow a little with a 2-bottom plow as my other tractor was laid up. I know a hydro isn’t recommended for tillage but had little choice at the time. The terrain there was quite hilly as well but it seemed to do fine even plowing up hill. No noticeable slipping and the oil stayed at a reasonable temp.
Still when descending a hill it seems to freewheel more than is comfortable. Pulling the lever back or throttling down may slow it somewhat but usually not stop it without the use of brakes. This is the tractor alone now with no load behind and always in low range.
Pulling the lever all the way to neutral usually will not stop it for some distance either depending on the grade of the hill. Moving it to the left toward reverse will however abruptly stop it.
Since it wasn’t the snap ring as I hoped what is my next step?
