Tractor Grader Blade Models

CH and CJ models attach to a Category I 3-point hitch. BH and BJ models attach to a Category II, 3-point hitch. All four tractor grader blade models feature dual blade configuration with dual 5/8" bolt-on standard highway punch motor grader edges, side pans with replaceable runners with heat treated wear strips on four corners, three 4" cross members bolted to side panels with high grade bolts.

Independent grading height adjustment on each side allows you to maintain a crown.

BJ model has twin manual screw jacks for height adjustment. Many of our competitors’ graders do not provide a way to adjust the grading height. In these graders the depth of cut changes as the blade wears. They typically use reversible, center-punched cutting edges. That is, the holes where the blade attaches to the mold board are punched in the center of the blade. When the bottom edge wears out, the operator must detach it and reverse the blade.

On our tractor grader blade models the grading height is fully adjustable. Our cutting edges are top-punched so that the top of the blade (not the center) attaches to the mold board. Thus as the blade wears, the operator can simply adjust the depth of cut to maintain the grading height and can get the full wear out of the blade without having to reverse it.

CH and BH models have a hydraulic tilt strut, which controls the lead cutting edge and manual screw jacks that control the trailing edge.

Our newest tractor grader blade model, the FR (Farm and Ranch) Series grader-spreader, attaches to a Category I 3-point hitch. It features two 3” cross members bolted to side panels, double ears welded to the front cross member, dual blade high configuration, 5/8" CAT high carbon steel standard top punched motor grader cutting edges (which do not require time and labor to reverse), and replaceable 2” skid bars bolted to side panels. Serrated cutting edge on front blade cuts and crumbles hard packed materials and eliminates the need for a scarifier.

The blades adjust by removing bolts on side panels to reposition blades and compensate for wear on cutting edges, provide ability to create a crown and pull material from shoulder to center of the road, set level to grade level, and adjust for varying job conditions and always work in an optimal cutting position.

Motor grader edges are available from any local heavy equipment dealer that sells motor graders.
