3 Bulldozer Sizes + How to Choose the Right One

While bulldozers come in various models and have myriad different features to choose from, there are three basic bulldozer sizes to consider: small, medium and large. The size is usually a good measure of the power and capacity of a machine — the bigger the bulldozer, the more powerful and better suited for big jobs; the smaller the bulldozer, the more maneuverable and better suited for small jobs.

Here, we outline the differences between bulldozer sizes and types and how to pick the right one for your job, whether you’re excavating a small area, grading, spreading out materials or doing some serious earthmoving. Let’s dive into the different weight capacities, horsepower ratings and capabilities.

Small Bulldozer Medium Bulldozer Large Bulldozer
Project Type Light commercial, residential Variety of residential and industrial Industrial
Terrain Soft, easy-to-navigate Various Rough, rocky
Operator Experience Beginner Intermediate Advanced

Small Bulldozers

Small bulldozers are the most compact option in the dozer category. Sometimes called mini dozers, small bulldozers are perfect for — you guessed it — small jobs like residential projects or working in tight places. You’ll typically find equipment in this category with a horsepower rating under 100 hp and a weight capacity of 20,000 pounds or lower. Small bulldozers are also equipped with tracks, meaning they’ll work well on soft terrain and maneuver deftly without sinking.

Small Bulldozer -up to 100 horsepower -Ideal for small residential projects - Weight capacity: under 20,000 pounds

Projects for small dozers include:

  • Small construction projects, like light earthmoving
  • Residential projects, like constructing a driveway or moving dirt for landscaping
  • Fine finishing and grading
  • Anything on soft terrain

Medium Bulldozers

Medium bulldozers are your go-to size for most projects for a few reasons. First, they’re in the middle of small and large bulldozers, making their size more flexible and adaptable to various projects. Additionally, they can often be more efficient — they’re bigger than mini dozers, warranting more power, yet still smaller than the biggest machines, making them more maneuverable and fuel-friendly. This perfect balance between size, fuel efficiency and power makes medium dozers a good catch-all size if you’re not sure exactly what you need for your project.

Medium Bulldozer -Up to 400 horsepower - Flixible and adaptable to various projects - Weight capacity: 20,000-100,000 pounds

Medium bulldozers typically have a horsepower of up to 400 hp and an operating weight from around 20,000 to 100,000 pounds. With this wide range of power and weight capacity, you can use medium bulldozers across a variety of projects, whether commercial, residential or industrial.

Projects for medium dozers include:

  • Larger residential projects, like landscaping
  • Small-to-medium-sized demolition and land-clearing projects
  • Small-to-medium-sized industrial construction projects

Large Bulldozers

Now onto the biggest of all: large bulldozers. This is most likely what you’re used to seeing in large industrial environments, like highway construction and mining projects. A large bulldozer is what you’ll need for plenty of power, efficiency and speed.

Large Bulldozer -Over 400 horsepower -Ideal for large industrial and highway construction projects -Weight capacity: 100,000–200,000+ pounds

Large bulldozers range from 100,000 to 200,000+ pounds of operating weight, and typically have an average horsepower rating of over 400. (Some models even go over 900 hp.)

Projects for large dozers include:

  • Projects on rough terrain
  • Projects in harsh environmental settings
  • Highway construction
  • Mining

How To Choose the Right Bulldozer Size

Now that you know the basic bulldozer sizes and what they’re generally best suited for, let’s dive into how to pick the best one for your project. Here are the main considerations to keep in mind:

  • Project: As we’ve covered, the type of project will be the top consideration for choosing the right bulldozer size. Small dozers are typically best for light commercial and residential construction projects, large dozers are good for large-scale construction and infrastructure, and medium dozers fall in the middle.
  • Terrain: This aligns with the project type and location. Depending on the terrain (rocky, soft soil, etc.) and weather conditions, you’ll need to pick the right dozer with tracks or wheels. Tracks are great for uneven terrain and wet, muddy locations; wheels are best for flat earth.
  • Operator experience: Safety first! Having the right experience level behind the wheel is crucial. Required skill level increases with the size of each dozer.
