Land Pride's BB3578, BB3584 & BB3596 Box Blades are a heavier 3-point Box Blade to complement our popular line of Box Blades offered by Land Pride. The beefy 3/8" x 4" x 4" main-frame tube and 3/8" end panels makes our 35 Series Fixed Bar Box Scraper ideal for construction sites and commercial operations or for use by counties and municipalities. Two welded channel braces extend from front to rear of the box plus welded gussets between the side panels and 23" roll-formed moldboard provide exceptional strength under heavy loads. The durable BB35 is comfortable dragging or back-filling.
