Caterpillar Motor Graders For Sale

Caterpillar motor graders are built for finish grading, road maintenance, ditch shaping, crown work, and base preparation where blade control matters more than raw pushing force. In the used market, Cat graders are often judged first by moldboard size, tandem condition, articulation performance, and how tight the hydraulic system feels under load. Larger models such as the Cat 16-series are common in heavy roadbuilding, mine support, and wide haul road maintenance, where a long wheelbase, substantial operating weight, and a wide blade help carry material and hold grade across long passes.

Powertrain choice is a major buying factor on older Caterpillar motor graders. Many used Cat units feature proven mechanical diesel engines and powershift transmissions with multiple forward and reverse ranges, a combination that appeals to buyers who want simpler field service and strong parts familiarity. Look closely at transmission shift quality, differential response, and final drive condition, especially on older machines that have spent years in aggregate, county road, or quarry work. Tire size, rim style, and brake type also matter because replacement cost adds up quickly on a grader, particularly on larger 23.5R25 setups and machines equipped for sustained road travel.

Hydraulics tell you a lot about the condition of a motor grader. Blade lift, circle drive, articulation, steering cylinders, side shift, and any rear ripper or scarifier should operate smoothly without hesitation or excessive seepage. Some older Caterpillar graders show minor cylinder leakage but still function well, so the key is to separate cosmetic seepage from weak hydraulic performance, sloppy circle components, or poor moldboard control. Buyers should also inspect the drawbar, circle, and moldboard for welding, excessive play, cutting edge wear, and evidence of hard impact work. On a larger grader, those wear points can affect grading accuracy and future repair cost more than engine cosmetics.

A Caterpillar motor grader is also known simply as a road grader, and the right machine depends on the type of finish expected. Fine grading contractors may prioritize predictable control response and tight front-end steering, while municipal and heavy civil buyers may care more about ripper configuration, frame strength, and the ability to maintain gravel roads or cut drainage efficiently. Cab condition, visibility, heater and air conditioning function, and overall operator station layout are worth checking because grader productivity depends heavily on long-hour operator comfort. For buyers comparing older Cat graders, a machine with strong articulation, responsive hydraulics, and a solid circle often brings more real value than one that only looks cleaner on first inspection.
