Plowing Snow with the Caterpillar 740 Motor Grader
#1
A machine built for winter challenges
The Caterpillar 740 motor grader, part of the long-running 700 series, has proven itself as a versatile tool not only for road construction and grading but also for snow removal in regions with harsh winters. With its powerful diesel engine, articulated frame, and hydraulic blade controls, the 740 can push through deep drifts and maintain roadways even under extreme conditions. In areas like Ontario and the northern United States, graders of this class are often the first line of defense against heavy snowfalls.
Terminology clarification
  • One-Way Plow: A snowplow blade designed to push snow to one side, often mounted on graders for clearing roads.
  • Wing Plow: An extendable side blade that increases clearing width, allowing operators to bench back snowbanks.
  • Shear Pin: A safety device that breaks under excessive load, protecting the plow and grader from structural damage.
  • Benching: The process of cutting back snowbanks to widen the roadway and prevent narrowing over the season.
Performance in deep snow
Operators report that the 740 can handle significant accumulations without the need for loaders, provided the snow is not excessively compacted. With the wing extended and the moldboard angled properly, the grader can push large volumes of snow while maintaining a clean shelf along the road edge. When drifts become too deep, switching to a V-plow or one-way plow allows the machine to cut through and gradually widen the path.
Operator techniques
  • Angle the moldboard upward when tackling frozen banks to reduce stress on the frame.
  • Use the wing plow for benching to prevent roads from narrowing after repeated storms.
  • Monitor shear pins closely, as they are designed to fail before structural damage occurs.
  • Adjust speed and blade angle to avoid overloading the grader when snow is wet and heavy.
Comparisons with other equipment
While loaders and dozers are sometimes brought in to push back snowbanks, graders remain more efficient for long stretches of road. A Caterpillar 740 can clear several miles of roadway in the time it would take a loader to handle a fraction of that distance. Dozers like the John Deere 750C are occasionally used for extreme drifts, but graders remain the preferred tool for municipal and rural road maintenance.
Historical context of the 700 series
Caterpillar introduced the 700 series graders in the mid-20th century, steadily improving power, hydraulics, and operator comfort. The 740, produced in the late 20th century, became a workhorse for municipalities across North America. Thousands were sold, and many remain in service decades later, often upgraded with modern plows and wings to extend their usefulness. The durability of these machines reflects Caterpillar’s reputation for building equipment that outlasts its design life.
Anecdotes from the field
One operator in New Brunswick recalled clearing a rural road after a blizzard where snowbanks towered above the cab. With patience and repeated passes, the 740 managed to reopen the road without assistance from loaders. Another operator in Ontario noted that while the grader’s paint job quickly suffered from salt and ice, the machine’s mechanical reliability never faltered, even after years of winter service.
Conclusion
The Caterpillar 740 motor grader demonstrates how a machine originally designed for earthmoving can excel in snow removal. With the right attachments, operator skill, and maintenance, it can replace or reduce the need for loaders and dozers in winter operations. Its legacy continues in newer models like the 870G, which build on the same principles with more power, advanced hydraulics, and improved operator comfort. For municipalities and contractors alike, the grader remains an indispensable tool for keeping roads open when winter delivers its worst.
