Bryan and Kraig, Thanks for the diagram and advice. It came right off once I started turning the adjuster the right way. What do you think of this find: 129 in good condition with, ag tires, 3 point hitch, spring assist, front blade, box scraper, snow thrower and "International" lawn sweeper for less than $1000? I was really happy to find the box scraper. Last year, 1200 with Brinley moldboard, single disc harrow, 44 inch mower deck, front blade, 3 point hitch and chains for $575. Only needed a new drive plate.
