It is a very quick process to switch either way with John Deere compacts assuming the loader and snowblower are also JD. Loader installation/removal takes maybe 2-3 minutes. To install the snowblower, a small bracket (with the hydraulic lift cylinder) is attached to the front of the tractor (2 bolts and a pin), a driveshaft from the Mid PTO to the front of the tractor is snapped into place, then you drive forward into the arms of the snowblower, snap the latches into place, and connect the PTO shaft to the blower and 4 hydraulic hoses to the same ports as used by the loader. This takes 15 minutes at most. Very fast and easy with no manual lifting. I have a JD 955 but the same type of connections are used on the 4000 series tractors.
