Yup, prices seem to be down all over
and CL. Ask is high, but on re-list prices are going lower as the reserves fall. In any case a complete implement is worth much more than one that is missing pieces. However, in the case of the blade -- there is always an exception. Many of us have pieces missing and want to be able to finish our own implements. Before you do part it, test the waters both in our For Sale Cub Items forum and of course your local CL etc.,.
Personally I would suggest if you do pop on the tractor that you hang on to the implements and see what you really need to do and what you can get out of them. Patience is usually rewarded with a higher final price achieved.
