We don't normally deal with the compact tractors here, and I'm not sure if any of our members have one. They may, but again, we don't deal much with them.
Does your tractor have the front PTO attachment? How about the front hitch and hydraulic kit? Near as I can tell at first glance, all that is required for the snowblower, but not sure. I am sure, that the PTO shaft will have two u-joints in it.
Is it a 5254E, or a 5254L? Serial number of the machine?
