I have a JD snowblower for my 1999 F935 that needs a rebuild bearing and seal kit or better yet a replacement. I have found an Eicher AM145228 that indicates it is a replacement for 47" tractor mount JD snowblower. Does anyone know if this a suitable direct replacement for front mount? Unable to find JD replacement, but found used JD part with same part number - looks identical to JD except fill hole.. Help?
