1250 hydro lift
 

Will a hydrolic lift off of a 1711 fit on a 1250. I know the valve handle will need to be changed any thing else.

They are quite a bit different, cylinders are different lengths, as well as how they mount I believe. Plus if the 1250 doesn't have a ported pump you will need it as well. I'm sure it could be done, I think you would have to drill the frame for the cylinder bracket, and use the rockshaft from the 1711 of course.
Not sure on clearances for the fatter cylinder, but I think it would fit.

1250 is ported, just no hydro lift.

Totally different parts and not worth trying to make them fit.

Yeah, im getting a new lifting mechanism for the tractor. So im sticking to the manual lift.
