Not sure if your deck is the same as my RC60-72H. On my tractor, if the hangers are still under the tractor, attaching it is pretty straight forward. It is a PIA to put on with one person, but I do it every spring. I have to take the deck and 2 of the hangers off to put on my front blade for snow. I've thought about trading the deck for a good finish mower. It takes me about a half day to make the change.
To install the deck, pull out the retaining pin & take off the front left wheel. Slide the deck under from the right side. It's a lot easier on a smooth floor. On mine, I have to put the PTO shaft together while attaching the hangers.
The height is adjusted with the 2 front outboard wheels and the center roller in the rear. I think there are 6 possible positions on the front wheel mounting spindles, and 6 notches on the rear roller adjustment lever. In operation the deck runs on the ground, it isn't carried by the tractor. Hope this helps.
