CHAD - The discussion about Sleeve hitch vs Cat O 3-pt was done a week, maybe ten days ago.
On a "standard" Cub Cadet, NOT a 982, 1872,2072, 1772, 1512, etc I think the sleeve hitch attachments work fine, are easier to find, cost less, and actually have a wider variety of different attachments to chose from. I'd go that route.
The Cat O 3-pt is O-K for those tractors I mentioned above, referred to as "SGT's", Super Garden Tractors since they are longer, wider, taller, have bigger tires, separate frt & rear PTO's, steering brakes, on board hydraulics & aux remotes. But to be honest, most of us who have them make Cat O to sleeve hitch adapters and use our sleeve hitch equipment. I've made a dethatcher and carry-all for my 3-pt, but the thing I use the most is the sleeve hitch adapter with my drawbar adapter bolted on. I never take it off. Plus the Cat O stuff is expensive, hard to find. Some people even rework Cat 1 equipment over to Cat O.
