Most of us are accustomed to seeing road graders in our everyday lives, from the side of the road to working hard on construction sites. They are one of the most used pieces of earthmoving equipment, but do you know much about how they first were created?
Road graders, otherwise known as motor graders, have been used for centuries to create level surfaces for driving or moving heavy equipment, but the technology has changed a lot in that time.
In this guide, we take you through the motor grader origins and how it has evolved over time. We hope that this article will help to educate people about this important construction vehicle and make the roads safer for everyone.
Origins Of The Road Grader
The first road grader is known to have been invented by American, J.D Adams, in 1885 and was called The Little Giant. It has two-wheels and a wooden blade which was hung or set at an angle (which could be moved from side to side depending on the angle of the road you needed to grade). The Little Giant was then pulled by a team of horses to get the grading done.
In 1896, Adams brought The Road King to market, which was considered an upgrade of The Little Giant. It has four wheels and this time incorporated a steel, eight-foot blade in its design. The Road King also had to be pulled along by a team of horses in order to be propelled forward.
The Evolution of the Road Grader
1920 saw the evolution of the grader moving from horse-drawn to fully-motorized design. The Russell Grader Manufacturing Company invented the first grader with an engine, which was essentially a modified tractor. They named it the Motor Hi-Way Patrol and essentially added a steel blade to a tractor which acted as a grading machine. World-famous manufacturer Caterpillar, bought the Russell Grader Manufacturing Company in 1928, and they made huge advancements in grader history.
They merged the design of the tractor and grader into a self-propelled grader, with the first one being released in 1931, and was known as The Caterpillar Auto Patrol.
Modern Day Road Graders
Whilst this history of graders shows the migration from graders pulled by horses to graders with their own engines for propulsion, the technology has come a long way through the ages to what, today, is known as modern day grader technology. Modern road graders are powered by diesel engines and can move more earth at fast speeds.
