Key Specs
The Cat® 140 motor grader is a mid-size machine ideal for road maintenance. It delivers the right balance of power, control, and blade reach for grading, crowning, and ditching. Maintain your gravel, secondary roads in comfort with the redesigned cab.
Keep working, not waiting. The Cat 140 has extended, synchronized maintenance intervals and centralized service access points to save you time. Optional High Performance Circle delivers reduced wear for greater accuracy.
Operators come first with improved climate control, plenty of seat adjustments, and enhanced all-around visibility. Boost jobsite safety even more with optional integrated rear vision, front vision, and 360° cameras that show in the main display.
Take control with your choice of joysticks or levers. The 140 is factory-ready for optional grade technology and built for easy attachment upgrades that help you expand your capabilities and get work done faster

Cat Grade with 3D for motor graders is a machine integrated grade control system that helps you get to grade faster with more accuracy, efficiency, and productivity. Automatic blade control reduces operator inputs and the number of passes to get the job done to save you time and money.
Cat® Grade with Cross Slope Assist is an integrated system that enables motor grader operators to achieve grade faster and more accurately by automating the cross slope of the blade, allowing the operator to do more in the same amount of time. Other cost-saving benefits of the system include lower fuel consumption and up to 40% less material usage.
