GX85 & SX85
These newer drive systems have some unusual features. The GX has the belt turned what might be considered inside-out. much older gear drives are more straight forward. The SX variable drive has been used for awhile and is considered by mechanics one of the most difficult of Deere drives to work on. Removal and installation of the belts is done from the rear left corner of the frame.
The routing of the deck belts uses the lower vertical of 8A and the "U" of 8B as the guides for the belts. The very top of 8B is also the guide for the drive. Final tightening is generally done with the deck engaged.

3xx and GX Series
The 3xx series and the GX3xx share the same configuration and the late model 3xx even share the same drive belt. Early 3xx models used a different belt. The GX255 has a design close to the Sabre garden tractor.
