I bought a used #451 snowblower to attach to my 1863 tractor. It looks pretty rough due to sitting out, but everything turns freely by hand. My problem is I did not get the attachment arm to hook up to the hydraulic post on the right side of the tractor. Does anybody have one? Cub wants $100 for a new one (ouch!). Anybody willing to send me a good picture and some dimensions of one. One last thing, I should probably changed the fluid in the gear box, what kind does it take? I have attached the cub cadet picture, arm is #32. Thanks for any help!
