I just spent $2100 on a Provac by Protero for my kubota zd21 with 60" stamped deck. I think the Protero system will be great but right now I'm having major blowout starting in the middle of the deck and blowing out to the right. I've already done the search and most everything refers to the exmark. Does anyone have a solution for the Kubota 60" stamped deck???? I have already lined the front of the deck with about 2" of door trim, this helped a little but not much. Please reply with helpful responses. thanks!!!!
