Enter the Circle of Trust - Graders Official

Caterpillar's High Performance Circle takes motor grader durability to the next level. Using proven excavator components, upgraded pin drives, and a redesigned blade carriage, the Cat 140, 150, and 160 deliver improved strength, longer service life, and lower cost per hour—backed by gains in safety, productivity, and reliability.

When it comes to pushing motor graders harder, longer, and more efficiently, component choice makes all the difference. In this video, Troy Karevski from Graders Official breaks down how Caterpillar’s High Performance Circle (HPC) is engineered using proven, heavy‑duty components to raise the benchmark for durability and performance.

From excavator‑grade slew bearings to an upsized pin drive and a redesigned blade carriage, the Cat 140, 150, and 160 graders are built for operators who demand more uptime, lower ownership costs, and confidence on every pass. Watch the video to see why entering the “circle of trust” changes the way grading gets done.

For the Cat High Performance Circle (HPC) proven and tested components were the only consideration for taking the Cat Motor Grader line to the next level.

The Cat 140, 150, and 160 models use a well-proven 320 hydraulic excavator slew bearing and upsized 14 motor grader pin drive to form the basis of it all.

The redesigned blade carriage also benefits from the HPC with key areas improved, in the blade pivot area and overall strength and engineering that provide a longer service life and lower cost per hour of operation.

With the safety, productivity, and serviceability benefits, the Cat High Performance Circle brings to the table there is only one thing left to do – now you’re in the circle of trust – let’s get grading.
