Darkminion, the decals on the dethatcher indicate it's a Model 100 Series.

According to the SDE brochure, it should be a Model 105. The front PTO driven model is supposed to be a Model 100. Does that agree with your literature?
I've been looking for a copy of that literature. Are you willing to sell the literature or a copy? I'd really like to have a copy for my website to make it more complete. I keep finding literature for Ford and Massey, but nothing for Cub Cadet. If you don't mind, please contact me through my website,
www.cubcadetman.com. That's probably a lot better than a literature discussion here. TIA
