From finish or long pass grading to ditch cleaning or sideslope work, you are certain to find a Cat motor grader to match your needs. Caterpillar unveiled the H-Series motor graders in 1994. They replace the legendary G-Series motor graders introduced 22 years earlier. The new H-Series motor graders offer durability, performance, high resale and reliability. Caterpillar added H-Series improvements including more power to the ground, better visibility, a more comfortable and quiet cab, lower emissions, and better control. With advanced electronics and hydraulics combined with variable horsepower options, longer wheel bases and a new blade design, the Cat H-Series motor graders allow you to handle in one pass what may take two or more passes with a G-Series model.
