Three of Caterpillar’s popular joystick-control motor graders are now available with a new High-Performance Circle, which delivers increased torque and requires “no adjustments for the life of the grader,” the company says.
The new circle is designed for JOY models of the Cat 140, 150 and 160 graders and replaces the previous open circle and drawbar. The graders range between 179 and 224 horsepower and operating weights of 42,647 and 45,547 pounds. Blade widths are 12 to 14 feet.
“Our new HPC provides more hours-of-service life, to significantly reduce planned maintenance,” says Eric Kohout, product application specialist for Cat motor graders. “Caterpillar’s industry-leading machining capabilities, designed to tight tolerances, help ensure high-precision alignment of the drawbar, drives and circle, so it requires no adjustments for the life of the grader.”
