There are many different types and sizes of bulldozers, and though they’re all classified under the same equipment category, you’ll encounter significant differences between the varied options. For example, a dozer for residential landscaping projects is very different from one used in mining operations.

Learn about the different bulldozer types and applications so you can make the best choice for your project.

What Size Bulldozer Do You Need?

When it comes to choosing the right dozer, one of the most important questions you can ask is what size bulldozer you need. The size of the dozer can have a significant impact on your project and efficiency. A bulldozer that is too big may not fit well in your jobsite, while a bulldozer that is too small could hamper your efficiency and slow down your operations.

The different bulldozer sizes include three main categories:

Small Dozers

Small or compact dozers — also called mini dozers — are generally rated at less than 150 horsepower with a weight capacity of around 20,000 pounds. Because of their size, small dozers tend to be more fuel efficient and move quickly, enhancing jobsite productivity.

These machines are perfect for tighter work environments or ones requiring heightened maneuverability and finesse. In most cases, small dozers are used for residential or light commercial applications where the terrain is soft.

Small Cat® dozers include the D1, D2 and D3 models.

Medium Dozers

With horsepower ratings between 130 and 310, medium dozers can do more heavy lifting than compact dozers. A medium-sized dozer will be your answer for most projects because it combines enhanced power while still maintaining maneuverability.

If you aren’t sure exactly what your project entails or want a more versatile machine, a medium dozer is the way to go. They can also handle rougher terrain than small dozers and tend to be easier to handle than large dozers.

Medium Cat dozers include:

• D4
• D5
• D6
• D6 XE
• D7
• D8

Large Dozers

If you’re looking for maximum power for your projects, large track-type dozers rated at 310 horsepower and above should be your choice. More common in mining, large industrial and highway construction applications, large dozers are built for the most intensive projects.

A unique consideration relevant to large dozers is operator experience. These machines require advanced knowledge of heavy equipment operations and safety procedures. If you’re looking into these machines, ensure you have staff with the right experience to operate them.

The Cat D9, D10 and D11 dozers fall in this category.

Other Factors to Consider for Bulldozer Selection

In addition to size, consider the following factors to guide your bulldozer selection:

• Terrain: When choosing the right equipment for your project, think about the jobsite terrain. If the ground is soft and relatively level, a small dozer may be your best choice, but if you’re working on rough terrain or steep grades, choose a medium or large dozer.
• Fuel: When renting or buying a new machine, you should also factor in fuel costs. Small dozers may be a bit more efficient but may require more frequent fuelings. Meanwhile, medium and large dozers will incur higher fuel costs, but the payoff is higher productivity rates.
• Budget: Smaller dozers generally cost less, so they may be the better option if you’re on a tight budget. However, time is money, so if the jump in productivity you gain from a medium or large dozer will ensure faster project completion and more revenue, go with the larger option.
• Tracks or wheels: Most bulldozers are crawler dozers because they operate on tracks, whereas wheel dozers operate on tires. However, tracks offer superior traction and control on rough terrain and in wet and muddy conditions. They also distribute weight more evenly to avoid tip-overs or sinking.
• Attachments: A definite plus for dozers is the availability of multiple different kinds of attachments. These include blades, rippers, winches and rakes.
• Grade control: Maintaining grade control can be tough, even for experienced operators. Dozers with advanced grade control systems can boost productivity and safety. Cat dozers come with the AccuGrade™ Control System, which offers up to 40% greater productivity and lower site costs.
• Renting or buying: Choosing whether to rent or buy a dozer can be complicated. For example, if you’ve recently won a large contract working on a huge highway construction project, it might make more sense to rent a large bulldozer so you don’t have to worry about maintenance and repairs.

Dozer Applications by Industry and Project Type

Determining the right kind of dozer for your project also depends on your industry and the type of projects you undertake.

Construction

Construction jobs include both residential and commercial building projects. In general, residential projects require equipment with greater maneuverability, while commercial and industrial projects may necessitate higher power requirements. Examples of construction projects include:

• Highway construction
• Road paving
• Home construction projects
• Urban road maintenance

Landscaping

Landscaping projects range from small residential projects to clearing land for future construction or use. In most cases, a mini dozer will be the best choice for landscaping projects because of its easy maneuverability and small profile. Examples of landscaping projects include:

• Moving dirt
• Clearing brush
• Fine finishing and grading
• Removing trees and stumps

Agriculture

Agricultural projects can range from small hobby farms to large industrial operations. Farmers need reliable and powerful dozers to complete tasks like drainage construction, field leveling and earthmoving. If you own a smaller farm, it may make more sense to rent your dozers during high-volume periods, saving you money on storage, maintenance and upkeep. Examples of agriculture projects include:

• Digging ditches and trenches
• Grading
• Waste and manure handling
• Terracing

Mining

Mining projects are often on a larger scale and thus require more robust machinery. Large dozers for mining need to be able to move and transport heavy loads of earth, rock and other debris. Examples of mining projects include:

• Moving overburden
• Pushing and grading material
• Creating paths for other machinery
• Land reclamation

Facility Management

Supporting a facility requires several different tasks, and a dozer can help with many of them. In the warmer months, dozers can assist ground crews with landscaping and smaller construction projects, and in the colder months, they can move snow and spread salt.
