New Mastless GRADE with 3D Technology

What is Mastless GRADE with 3D?
"Mastless" takes GRADE to the next level by integrating the GNSS (Global Navigation Satellite System) receivers (GPS) and IMU (Inertial Measurement Unit) grade sensors right into the grader, without restrictions from masts (antenna-like sensors) sticking out or cables getting in the way.

Increased Operator Performance & Visibility
Without the GNSS blade masts, the operator will experience a better overall performance and a safer environment.

Do More Work
The mastless system allows for closer proximity work such as alongside buildings, all while maintaining accurate grade. This grader is suited for finishing applications, such as side slopes and drains, that were not previously possible due to the existing mast positions.

What are the other enhancements?
Automatic Blade Control
Reduces operator inputs and the number of passes to finish the job - saving time and money by reducing the costs associated with re-work (fuel, labour and material costs).

New Enhanced Large Touchscreen Display
Puts the design plan clearly in front of the operator and operates like a tablet. Grade control buttons are now integrated into the joystick controls for seamless operation.

Caterpillar’s Industry Exclusive E-Fence
Fully integrated into the grader, this technology prevents the moldboard from hitting the tyres and ladders and stops the circle from potentially damaging the link bar.

Cross Slope Auto Included with Mastless GRADE with 3D
Allows the operator to manually control one side of the blade while the other side is automatically controlled to maintain the preset cross slope, reducing operator fatigue.

Cat GRADE for Motor Graders

Out with the old. In with the new.

Before Caterpillar® introduced Mastless Motor Graders, tall masts GPS systems had to be mounted to the ends of the moldboard, exposing components to potential damage from the environment and theft.

Due to the threat damage, the masts often had to be removed and remounted daily resulting in unnecessary downtime and added hassles for the operator. The constant removal and installation of the masts causes faster wear and tear, and increases the ongoing cost associated with running the grader.

The location of the masts also limited the blade's range of motion, resulting in limited types of applications.

The first Cat Motor Grader models equipped with the new mastless technology that delivers maximum productivity are the Cat 140 Motor Grader and Cat 150 Motor Grader.

Cat 150 Mastless Motor Grader

Can I retrofit an older motor grader to be mastless?

Yes, an older Cat Motor Grader can technically be retrofitted with mastless technology. However, you'll see a lot more benefits if you buy new. The platform for the new machine provides an engine with increased grunt and all of the other enhancements listed above. When this is combined with mastless technology, you get the most powerful grader on the market.
