We specialize in 16 row 30" mounted vertical fold planter toolbars but we have done many other configurations and can do pretty much any mounted toolbar for other applications other than planters. Our toolbars are double bars with a 5x7 front bar and a 7x7 rear bar. We put the vacuum in the bar for a cleaner planter build and we have a hydraulic block that controls wing down pressure so no weights are needed to keep the wings in the ground. This hydraulic block can be set at any pressure to optimize different field conditions.
