Caterpillar has upgraded its 140 motor grader to the next generation platform.
The new grader featuring the next generation hallmarks of efficiency, productivity and operator comfort, made its first appearance at bauma in Munich.
The Cat 140 is due for production in the first quarter of 2026.
“Versatility in operation has always been Caterpillar’s strength, and the 140 Motor Grader has been a classic demonstration of that virtue,” said Pablo dos Santos, Caterpillar Global Product Application Specialist.
“Over the years, customers have shown that the 140’s usefulness and flexibility has few limits. Its frame lends itself to easy transportation, and its power and performance have seen it put to work in everything from snow clearance to sugarcane operations, in addition to its everyday use in roadbuilding and ditching.”
Safety & efficiency
To improve safety and efficiency, Cat integrated the highly successful cab design from the 120 next gen models into the 140 motor grader.
Larger windows provide better visibility out of the cab, ensuring better all-round views, including moldboard and tires, while a standard rearview camera augments direct lines of sight. The camera system also provides an optional 360-degree view around the machine, while the People Detection feature boosts safety.
“People detection can identify people standing behind the motor grader and provide a visual and audio signal to the operator, depending on the distance where the person is located,” said Marina Makarova, Product Application Specialist with Caterpillar.
The camera feed is integrated into the 25-cm touchscreen, which also provides operators with access to other next generation functions such as Cat Grade.

A new seat takes advantage of the next gen cab’s greater foot space and hip room, offering a variety of adjustments to improve operator comfort and reduce fatigue. The cab also features revised seatbelt and safety harness options.
The motor grader’s joysticks also benefit from the next gen upgrade. While Caterpillar has stuck with its industry-exclusive three axis joystick system, which studies show is more ergonomic for operators than levers and a steering wheel, the 140 makes several updates to the joysticks themselves to help further boost productivity.
The new Cat 140 continues its proven design and exceptional reliability to ensure low operating costs coupled with favourable fuel efficiency. The 140 features banked and centralized access checkpoints that make daily maintenance a breeze rather than a bind.
“What’s more, the new 140 provides a ‘sweet spot’ power-to-weight ratio with excellent fuel consumption rates,” dos Santos said. “There is a lot of good information collected so far from the multiple machines being tested in the world with more than 40,000 hours accumulated so far.”
High Performance Circle
The 140 motor grader is also available with Caterpillar’s High Performance Circle, which is designed to improve performance, efficiency and uptime thanks to a longer lifespan and increased service intervals. The enclosed design of the High Performance Circle reduces wear on teeth and reduces the number of components to service.
With the High Performance Circle installed on graders, operators have greater confidence in meeting grade elevation tolerance due to reduced wear between circle and drawbar.
“We don’t have any wearing inserts for the shoes to connect the draw bar and the circle,” Makarova said, noting the High Performance Circle also eliminates play between the two components, eliminating the need to make adjustments.
“We reduce operating and maintenance costs because we don’t have any wear components anymore. All we need to do is just to grease this circle regularly.”
The new Cat 140 also offers expanded technology capabilities, from simple features to improve operator’s comfort, like the stable blade, to fully calibrated 3D systems for reduced total cost of ownership.
“It’s exciting to see Caterpillar’s most popular motor grader model joining the Cat 120 Motor Grader receiving next generation treatment,” dos Santos said.
“We expect it will only add to the machine’s popularity.”
