Nice work, and yes the Kubota kit is over priced
I did mine like this, as to save the 3rd function for my hydraulic toplink. The blower on the front and box scraper on back is the best snow set up I've ever had.
I know there are a few posts on here about doing this, my question is can it be used to put down pressure on 3pt impliments with a cylinder of course and what controls this if you add ther rear ports, Now Im very mechanical but no nothing about hydrolics... so be nice :) Thanks
