[scf84]

got a massey 41 mower that im rebuilding and the arm that connects the wobble box to the frame thats has the pvc bushing in it is bent. does anyone know what this is made of? not sure if i should hit it with sledge and try to straighten or take to machine shop to a press. you can click the link below to go to a post with a picture.

I think a press would do best, possibly with some heat on it first to soften it up a little... I'm not familiar with it so I don't know what it's made of... On our JD sicklebar mower it's made of wood!
