Hello everyone, my uncle has a Zetor 7745-1988, it used to be a well used and was a great farm tractor, but in the past five to ten years the farming has pretty much ended besides the odd hay cut & bail... We use the tractor for blowing snow, and splitting wood ect. So in the past year or so the hydraulics have been getting pretty week, for instance if you tried to lift the blower it would seem to take FOREVER. but when you first started the tractor it would work great just after a few minutes or so it seeemed to have no pressure.... Anyway my question is has anyone ever heard of this AND does anyone know or maybee have a diagram of were the hydraulic pump is, we've asked a few people and got a few answers but before we start ripping things apart I thought I'd ask people that may know more!!! Any and all help would be appreciated, thanks!!!!
