I Just bought a JD 445 and I bought a snow blower and plow from someone else. The blower came with the driveshaft and a support bearing. This blower allegedly is for a 425/445/455. The blower came with a drive shaft support bearing shown below. I don't see any place on the tractor that have this bolt pattern to accept this bearing. I do have what appears to be a pass through for the front axel. Where do I mount this bearing? Thanks!
