the check chains mount just above the 3 pt hitch pins on the mower. The RM500-2 parts book shows 7/16 x 1 1/2" bolts there and 1/4" proof coil chain x 32 1/2" long. They mount to the tractor by 2 special links that mount below the center link mount with a 3/4 x 6 bolt. I can scan some of the parts book if you send your email.
