Which Type of Motor Grader is Right for You?
Finding the perfect motor grader for your project can seem daunting. With their various frames and sizes, how do you know which combination is right for you? This blog will guide you through the different types of motor graders, helping you make an informed decision before purchasing a second-hand grader for sale.
Sizes
The first step to finding your ideal motor grader is considering size. Motor graders come in small or compact models, all the way up to medium and large machines.
Small Motor Graders
Small motor graders are the most compact of the bunch, allowing for easy transportation and great fuel economy. Popular models include the Cat 120 and Cat 140, which offer strength despite their small size.
Small graders are not ideal for heavy-duty projects because of their small frame and blade size, however, they fit perfectly in spaces that larger graders can’t reach. For small construction jobs, landscaping, and work in tight areas, consider a small motor grader.

Medium to Large Motor Graders
Medium and large motor graders offer more power and efficiency for expansive projects and heavy-duty work. Models like the John Deere 870G are popular mid-size machines, while models like the Cat 14M are large motor graders that excel at big projects.
If you have a heavy workload and aren’t worried about your machine fitting in small spaces, a medium or large motor grader will be the most powerful and productive choice for your worksite.

Frame Types
After you consider size, it’s time to consider the frame. Motor graders come in two frame types: rigid and articulated.
Rigid Frame Motor Graders
Rigid frame motor graders consist of one solid frame. This makes them great for straight line grading and working on flat surfaces, thanks to their simple design. Consider a rigid frame motor grader for small to moderate scale tasks and work in open areas.
Articulated Frame Motor Graders
Unlike their rigid counterparts, articulated frame graders can bend, or articulate, thanks to a joint between the front and rear axles. Because of this, articulated frame motor graders can maneuver in small areas and often have a tighter turning radius. An articulated frame motor grader is the way to go for work in tight spaces and larger-scale projects.
Conclusion
No matter the project, there’s a motor grader size and frame type to match your job site. Use this guide the next time you’re in the market for a grader to simplify your search for the right machine at the right price.
