Hi all, I just aquired a 1974 646 that i am having some questions about with the tractor moving in forward. I have never owned a 646 and do not know what to compare to. All of the linkage was worn pretty badly so we purchased the entire banana plate and all linkage etc associated with it from Salem Power Equipment. The hydraulics seem powerful with the lift and the bucket curl. The 3 point goes up and down pretty quickly. When it is in reverse in either hi or low range it will peel the tires but in forward it seems really sluggish and takes a while to get going. I would have figured it would be a little more identical in forward and reverse. Is it more of an adjustment of the link to the valve or are these designed to be like that. There is not anywhere the pedal movement in reverse as there is in forward. Or is there the possibility of a bad o-ring in the valve body? Any suggestions are greatly appriciated. Like I mentioned earlier, I have never owned one and have no way to judge what it should be like.
