Does anybody have any experiance with Uni-Tatch snowblowers. I found one for a John Deere 420/430 garden tractor and would like to mount it onto my 755. The blower looks like it is in great condition but I can't find any info about them. I haven't seen it in person yet so not sure how close the mounts are. I already have all the tractor side mounts and shafts for my tractor but they are JD brand.
