Caterpillar has unveiled a new joystick steering option for its next-generation 140 motor grader, giving operators a choice between joystick (JOY) and traditional lever/steering wheel (LVR) controls. The update also includes a new nine-speed transmission, enhanced visibility, and an array of technology upgrades designed to improve efficiency and operator comfort.
The 140 JOY made its global debut at Bauma 2025, followed by the 140 LVR at the 2025 Public Works Expo. Moving forward, both configurations will be offered as options rather than separate models, similar to Cat’s other features like drive systems and attachments.
Easy-to-Learn Joystick Controls
Caterpillar emphasizes that the choice between joystick and lever is not one-size-fits-all. Contractors often select control systems based on the type of work. Joystick controls are particularly suited for bulk tasks, while some operators prefer the feel of lever steering for fine finish work.
The ergonomic three-axis joysticks consolidate multiple functions: the left joystick manages transmission, gear shifting, and machine direction, while the right joystick handles the drawbar, circle, and moldboard, along with electronic throttle control and differential lock/unlock. Caterpillar reports that the joystick setup reduces wrist and hand movements by up to 78%, lowering operator fatigue while enhancing productivity.
Advanced Cab Design and Visibility
The next-generation cab features angled doors, a tapered engine hood, and a sloped rear window to improve visibility of the moldboard, tires, and surrounding work area. Standard rearview camera feeds are displayed on a 10-inch touchscreen monitor, with optional integrated smart cameras and a bird’s-eye view for comprehensive machine awareness. Cat Detect – People Detection alerts operators when someone enters the grader’s hazard zone.
Integrated Technology for Precision Work
The 140 motor grader comes equipped with advanced in-cab systems, including:
- Cat Grade 3D Ready: Integrated grade control for faster, more accurate grading.
- Automatic Blade Control: Reduces operator input and the number of passes needed.
- Cat Cross Slope Assist: Allows operators to control one end of the moldboard while the system manages the other.
- Additional Features: Position Sensing Shift Cylinder (PSC), E-fence avoidance, and dual IMU sensors simplify upgrades.
These systems improve precision, reduce manual input, and maximize operational efficiency across a range of applications.
Performance, Maintenance, and Transport
The next-generation 140 offers a balanced power-to-weight ratio and excellent fuel economy. Centralized service points and extended maintenance intervals minimize downtime, while the narrow 98.9-inch width facilitates transport. With a net power of 248 hp, a 12-foot blade, and 9 forward/6 reverse gears, the 140 motor grader is equipped for snow clearing, roadbuilding, ditching, and general grading tasks.
