I did not know the Echo attachments and Cub a Cadet attachments would interchange. I am going to purchase some Echo stuff next week. I have a pole saw, hedge clippers, edger, brush blade, and cultivator that all fit the Cub Cadet. I have a dead Cub Cadet 27cc power head and a 27cc that runs great. I just need to get rid of the Cub Cadet because it uses 40:1 oil and the other equipment I run uses 50:1 and it is a pain to keep separate gas mixed. I figured I would have to sell all of the attachments as well.
