It is a quad
Sounds like it only happens once in a while.
talked to him today but really didn't get a straight answer.
Will wait till it warms up and then try it myself
Thank you for the information.
Mt brohter in law has a 4630 and says it shift hard.
He says this is normal in this tractor. Is there an easy fix. He is retired and would like to sell it but wants this fixed first (very fussy).
