This is more or less how it went:
I removed the mower deck, marking the various arms and mounting pins so I knew where everything when. I dragged the deck away from the tractor, cleaned it thoroughly, primed the bad spots, and repainted the deck with matching paint. I masked all of the decals so they still looked sharp when I pulled off the tape.
I replaced the secondary drive belt and the primary belt. Once it was roughly in place, I fooled around with the spring until I found a place that would hold it under tension and seemed far enough to stretch it.
I hooked one end to the bracket and using a tool I made of a thick piece of wood and a piece of 550 cord, I stretched the spring until I could hook the other end. (Be careful not to aim the spring at your head in the event it comes loose.) I had no problem slipping the 550 cord from behind the spring.
I double checked the operation of the spring and pushed the deck back under the tractor and placed the drive belt around the drive pulley. As I had marked the deck supporting locations, I had no trouble putting it back on the tractor.
Once the deck was back under the tractor, I leveled it while it was parked on my driveway.
I think removing the deck was the simplest thing to do; I might have been able to do everything with the deck on the tractor (I don't know) but this way everything was free and clear and I could repaint the rusty spots.
