I already asked this on the Massey Ferguson site but realized any person with any tractor could help me. I do not like the original seat on my Massey, it is so hard and uncomfortable, my older metal seat on my Oliver was a lot smoother. So I looked and saw that Grammar model 85 looked like a lazy-boy seat, seem comfortable and is a mechanical seat ( not pneumatic ). I want to know if anyone bought this kind of seat or any other make will do but it has to be a smooth ride . I do not want to make an error because those seat are not cheap ( some are near $900 cadn). My Massey is an open station but it sleeps inside. Thank you for your help. Roger
