62C Deck Rebuild
I have a 62 deck that came with my "new" 2005 X585. Unfortunately it appears to have seen some weather and little maintenance, so I am going to rebuild it before spring arrives.
Looking at the JD parts page, it looks like they upgraded some things on the deck starting in 2012, SN 300,000. This includes a different belt, V grooved sheaves replace the flat idler and tensioner pulleys, and a different tensioner spring and mount (bushing) are used.
Looking at my deck, there is evidence of the belt slapping around, a well as wear on the belt from the original flat pulleys. My idlers are pretty much beat and need replacing so I am going to update the drive train on this deck to the latest configuration.
The last picture shows a mockup with the new belt, spring, and sheaves. The new spring is shorter and heavier, but would not fit over the new bushing that I received. The old spring does fit. For now I am using the old spring bracket. I might try turning a groove in the busing so I can use it.
I have seen the old and new belts listed with the same lengths, but the new one appears to be about 1" shorter, measured around the outside. The gap between the tensioner and the bumper also decreased from 2-1/4" to 1-1/4" with the new belt and sheaves. I am not sure if this difference is due to stretching of the old belt.
If someone has a picture of the newer tensioner configuration it would be interesting to see how Deere sets it up.
