Ralph, I lucked out and a friend gave me what was left of his Cole 4 row planters. I got a 14ft 2 1/4" diamond toolbar, solid steel. I got the clamps and 4 disk hillers, clamps and 2 cultivator shanks, clamps and 2 depth gauge wheels , and one Cole planter unit. I cut the toolbar into 2 5ft bars and a 4 foot bar. I used the clamps to add the 4 foot bar behind the 5 ft bar and attached the planter and 2 spring cultivators to the rear 4 ft bar . I added 2 disk hillers and the wheels to the front 5 ft bar. I haven't tried it yet, but it looks like a winner. I haven't seen any clamps for the diamond toolbars at agri-supply. I did see some in a Ferguson book my local dealer had which had all sorts of clamps and toolbars. He quoted about $270 for a 80" 3pt diamond toolbar. I think some af the clamps were around $75 . The machine shop quoted $400-$500 to make a toolbar from scratch. If you can find old equipment, it's worth the effort. I have a lead on another 4 row planter I'm going after /forums/images/graemlins/grin.gif
