Built to push. The 400x86x49 Multi-Bar puts continuous transverse bars on the ground for maximum forward drive — the tread you want when you're grading, dozing, and moving material all day. Multi-Bar Tread — Built for Pushing Power Repeating full-width bars bite hard on the push and the pull for the straight-line traction heavy grading and dozing demand, while open channels between the bars clear debris so grip stays consistent. This tread turns engine power into ground drive. Built Heavy-Duty A continuous steel-cord core runs the full loop with no splice to stretch or fail.
