I purchased a cc2554 and the electric sleeve hitch in Dec05. My previous tractor had the manual sleeve hitch. For me, I like the electric hitch much, much better.
My dealer installed a toggle switch on the dash board to operate the hitch...works like a charm.
With the manual hitch, I had to remove the deck in order to use an attachment. With the electric, the deck can stay on.
The electric hitch from CC is pricey, around $950 or so, but for my money, it was worth it.
Also, I own some Brinly attachments and some made by Agri-Fab.
I purchased a core aerator with drum (holds water for weight). Previously, I had a core aerator which required weights, such as cinder blocks. I find the "drum" type much better for my purposes.
