Pull-Behind Disk Eliminates One Pass Through Field

Pull-Behind Disk Eliminates One Pass Through Field DISKS Disks (58D) 18-2-9 Monticello, Minn., farmer Greg Thune cut out one trip through the field by constructing a pull-behind disk that he tows in back of his semi-mount moldboard plow. He used 5-in. dia. steel pipe to build a bridge hitch that hooks up to the front of the plow beam - just behind the tractor - with a single drawbar pin. He made the 5-ft. wide disk by cutting down a 10-ft. McCormick-Deering tandem disk that he bought at an auction for $25. The disk frame and bridge hitch were both fashioned out of scrap steel. "The 5-ft. width of the disk matches up with my plow, which has three 16-in. bottoms. The angles of the disk are adjustable by removing two bolts and sliding the gangs to different holes. My plow extends straight back behind the tractor but the disk pivots, following the tractor on turns. I hooked on at the front of the plow beam, rather than at the back, so the disk wouldn't pull the plow off center. I first made the bridge hitch out of 4-in. dia. pipe but it wasn't strong enough. Now I can even back up in fresh plowed ground with no problem," says Thune, noting that last year he only had to use his regular disk on dead furrows and headlands. "This disk is making money for me by cutting time in the field, lowering fuel expense, and reducing tractor wear and tear," says Thune. Contact: FARM SHOW, Followup, Greg Thune, 162 Co.
