Yes...sort of...Do a search here on TBN ...for Ratchet rake and Ratchet rake 3pt etc. and you should find the thread ...it was within the last 30 days or so ...seems to me..
you are right renkees - however you can use the toplink angle to dig more or just float over. I agree its better to have it on the FEL where it was originally designed for. However I dont see a problem being innovative by adding weights to make more downforce since some tractors that just dont have any FEL. You could use a boxblade and strap it on that since its already heavy for some downforce action.
