If the tractor has a FEL, it's cake. If its an RC-60, disconnect PTO, lift arms, front link. Lift the front of the mower with the loader bucket, pull the mower from the discharge side, put the tractor back on its tires. Takes me less than 5 minutes now.
IIRC, the operator's manual says to park the rear wheels on blocks jack and jack stand the front, or drive over the mower. My memory is as little foggy there. Glad I don't have to deal with that bs.
