Thanks for the thought... But it was several weeks of parts spread across the garage floor. One of the axels broke. Had to take the differential off the transmission. The hose was the oil return to the transmission. During this time I tried to keep the mess to a minimum, getting rid of old parts. I didn't notice the spring during disassembly nor in the parts breakdown. It was the Deere parts diagram that showed the spring with p/n. Major Deere dealer (35+ locations) said they have only sold 3 springs in their entire history. I feel, at least, I'm not the only one to throw it away.
