Benefits and Features

The D4K2 Dozer offers numerous grade control features to enable operators to grade with increased accuracy. Features such as Cat® GRADE with 3D, Cat GRADE with Slope Assist, AccuGrade and Slope Indicate allows for a smooth finish grade for both new and experienced operators every time.

The family of Small Dozers offers a choice of both track frames and undercarriages.

Track frames are available in two configurations:

• XL undercarriage - where flotation and side stability are not extreme
• LGP undercarriage - for soft underfoot conditions where additional flotation is required

Undercarriages are available in two configurations:

• Sealed and Lubricated Track (SALT) Undercarriage
– Track is not bushing limited
– May require pin and bushing turn

• SystemOne™ Undercarriage
– Track is bushing limited
– Bushing rotates continuously
– Does not require bushing turn
– Designed to maximize the life of all undercarriage components

The spacious, comfortable cab helps keep you relaxed and productive throughout the day.
