Cat Motor Graders (2019)

New names, same productivity and comfort.

A clear line of sight down the road of innovation

Over their 85 year legacy, Cat Motor Graders have featured either a two or three-digit model number, followed by a letter designation, with the numerals remaining consistent and the letter typically changing with the release of a new model. These current model numbers and letters do not easily identify with size or application, which can be confusing for customers and employees alike.

As a result, Caterpillar has identified the need for simplification of the motor grader lineup so that you have more clarity when making a purchase. The goal is to realign the nomenclature with relative machine size, not to change model positioning or pricing. Our construction class models will be identified with a three-digit number from the smallest to largest (120, 140, 150, 160) while the mining class will be identified with the two-digit number (14, 16, 18 and 24) representing blade length.

How are the model names changing?

Construction models:

  • The 12M model number will be replaced by model number 140
  • The 140M model number will be replaced by model number 150
  • The 160M model number will be replaced by model number 140
  • The 160M model number will be replaced by model number 160
  • The 120M model number will be replaced by model number 120

Mining models:

The only change to this line up will be dropping the suffix:

  • 14M3 > 14
  • 16M3 > 16
  • 18M3 > 18
  • 24M > 24 

What do I need to know?

How does the nomenclature change affect part numbers?
It doesn't. To get the right parts for any Cat motor grader, all you need to know is the model name and machine serial number - same as today!

Will the new nomenclature affect all regions globally?

Will motor graders use the GC designations?
Yes. Caterpillar may introduce GC motor graders in different size classes and different global regions based on the specific geographic demand.

Does simplified nomenclature mean fewer configurations?
Not at all - in fact, there will be more opportunity to configure graders for your specific applications than you've had in the past.

When will we see these in the market?
The Cat 24 motor grader has arrived at WesTrac with the rest to follow soon.
