Key Features of the CAT 140M Grader


Engine power and reliability

If you are looking for power and reliability in your grader engine, you don't need to look any further than a CAT machine. The company has a huge amount of loyalty across the industry for a reason. With a large number of graders to their name, you might be wondering why you would choose the CAT 140M over the others. The top reason is the engine. The machine comes equipped with a Cat® C7 ACERT™ engine which is built to perform.

The C7 gives you the ability to maintain consistency across your grading speeds for maximum productivity over the entire job. When it comes to heavy loads, the CAT 140M grader offers high-grade torque and the ability to maintain pull over long distances, while coping well with sudden changes in speed. Inside the C7 engine, there is a hydraulic demand fan that automatically adjusts speed based on the temperature of the engine, so that the risk of overheating is drastically reduced.

As an added bonus, the Caterpillar 140m grader engine incorporates ACERT technology giving you enhanced fuel consumption with fewer emissions. That means savings for you and the environment. Overall, the CAT 140m grader specs give the sheer power you need for heavy jobs, while also being reliable when you need it most.



Unmatched performance

The Cat 140M was made to improve productivity and performance over previous models. Ergonomics and durability were obviously a key focus when designing the frame and drawback components because it is easy to see how they will perform a variety of jobs.

All cutting edges and bolts are heavy-duty, and the aggressive blade angles will allow for all types of strata to roll easily along the blade. Whether you are dealing with soil, gravel, or rock, the Caterpillar 140m grader will be up to the task. Another factor that's important when considering performance is the hydraulic system.

The CAT 140M comes standard with an advanced electro-hydraulic system and a high-grade load sensing system, offering great control to your operator.



Comfort and control

The CAT 140M grader has the biggest and most comfortable cab in the industry. A spacious cabin might seem like a luxury, but it can actually be a key feature in reducing operator fatigue and can increase productivity overall.

There are no levers present inside the cabin, only a joystick. This frees up space and minimises the need for lots of arm movement. With a fully adjustable seat, all control levers within easy reach, fully adjustable heating controls for dehumidifying and pressurising, and programmable MP3 and Bluetooth technology, this machine gives a little bit of luxury when it comes to your heavy lifting.

When maneuvering the CAT 140M , you will notice an ease of visibility due to the clever design; a sloped rear window, angled cab doors, and a tapered engine enclosure make it easy to see all angles. Not to mention, you can also add an optional rear vision camera for improving the line of vision even more.


Caterpillar 140 M Grader Summary

The Caterpillar 140M grader has marked the dawn of a new era in grading technology, with improved safety, comfort, design, and performance. As you can see, there are plenty of good things that can be said about the CAT 140M grader. Whatever job you are trying to tackle, you can be sure that the CAT 140M will be up to the task and will give you maximum power.

However, as mentioned before, you can consider second-hand purchasing, or hiring the equipment, so that you can still make the most of all the great features the 140M has to offer. Even a novice operator will feel comfortable in this machine; it's just so intuitive, comfortable, and easy to operate.
