When comparing bulldozers in the mid-size class, two trusted names stand out: the
CAT D6N
and the
Deere 450C Dozer
. Both machines offer proven reliability in earthmoving applications, but they differ in power, size, and the types of jobs they’re best suited for. Whether you’re upgrading your fleet or buying used equipment, understanding the distinctions between these two dozers can help you make an informed decision.
Engine Power and Performance
The CAT D6N is equipped with a Cat C6.6 ACERT engine that delivers approximately 166 horsepower. This gives it strong pushing power and consistent performance on challenging terrain. It also features an advanced hydrostatic transmission and differential steering, giving operators better control and maneuverability under load.
The Deere 450C, on the other hand, is a lighter-duty dozer that features a Deere 4219D diesel engine with roughly 65 horsepower. While not as powerful as the D6N, it’s well-suited for lighter grading jobs, small land clearing, and residential construction tasks. Its compact footprint and ease of transport make it a favorite for contractors working in tight spaces or with frequent equipment relocation needs.
Weight and Size
The
CAT D6N Dozer
weighs in at around 36,000 to 39,000 lbs depending on the configuration. Its size and weight give it superior traction and blade down pressure—key advantages when working with dense materials or slopes. The D6N’s wide track options also improve flotation in soft ground conditions.
The
Deere 450C Dozer
is significantly smaller, with an operating weight of approximately 14,000 lbs. This makes it more fuel-efficient and easier to trailer between job sites, though it doesn’t offer the same pushing force or depth control as the D6N. That said, its lighter frame can be a benefit when working on turf, finished grading, or landscaping projects.

Operator Comfort and Technology
The CAT D6N comes with a fully enclosed cab and optional climate control, ergonomic joystick controls, and modern electronics. Many models include Grade Control systems and real-time diagnostics to improve efficiency and reduce rework.
The Deere 450C, being an older model, has a more basic cab with minimal electronic assistance. Its simplicity can be an advantage for operators who prefer mechanical reliability over modern tech, but it lacks the advanced comfort and automation found in the D6N.
Parts Availability and Maintenance
Both machines are well-supported in the aftermarket parts world. The CAT D6N benefits from Caterpillar’s global parts network, and many components are readily available for both new and used models. It’s a common model among fleet owners, making parts interchangeability easier.
The Deere 450C also enjoys good parts support thanks to its long production run and popularity. While some OEM components may be harder to find due to its age, there’s still a robust supply of aftermarket Deere 450C parts and rebuilt options that help keep these machines working affordably.

Which One is Right for You?
If you need a high-powered, technologically advanced dozer for large-scale site work, the
CAT D6N Dozer
is the clear winner. Its horsepower, weight, and blade control features are built for serious production in demanding conditions.
However, if you’re looking for a reliable bulldozer for smaller grading jobs, landscaping, or utility work, the
Deere 450C Dozer
offers solid performance at a lower cost—with easier transport and simpler maintenance. Ultimately, your decision comes down to budget, job type, and operational scale.
