What are the different types of dozer blades?

Once you've decided on a dozer, it's time to take the dozer blade into consideration. There are a lot of different factors that go into choosing the right blade for a particular task. Manufacturers put a broad range of factors into the blades that they pair with their dozers - the right architecture, structure and size of the blade can make a big difference in performance and the quality of work being performed on the job site.

PAT blade

The Power Angle Tilt (PAT) blade tilts and angles using hydraulic power. This is the most popular blade type for mid-sized and small dozers, as it offers increased versatility and is good for both general dozing and finish grading. PAT blades have also evolved to become very durable, which makes them a more common blade choice for mid-sized dozers.

C-frame blade

Manual Angle Power Tilt is an outside C-frame blade that can be manually angled, but offers power tilt capability. This blade often finds use on pipeline right of way.

S-blade

S-blades, or straight blades, are the shortest type of bulldozer blade and are used on large mid-size dozers and up. These blades will generally have blade tilt, and on larger dozers will be available with dual tilt. They can pitch the blade forward for aggressive cutting and back for more efficient blade carry. 

U-blade

A full U blade includes large side wings that form a pocket in the blade for greater load carrying capacity. For general and rock type applications, the semi U blade is the most popular. In high volume and downhill dozing, the full U blade provides greater performance because of its better load carrying capabilities.

Cushion blade

Cushion blades are generally only found on large dozers; these are very specialized narrow blades used for push loading scrapers. Rubber biscuits cushion the shock load when the dozer contacts a scraper at the beginning of the push. The blade is narrow to help prevent contact with scraper rear tires.

Six-way blade

Six-way blades offer increased blade maneuverability and can be used in a wide range of applications. Grade control supports the experienced operator with the ability to hold consistent grade throughout the day and enables a novice operator to get up to speed quickly. 

What to consider when choosing a blade for your dozer

Today's contractors and fleet owners are looking for bulldozers that handle heavy dozing, spreading, finish grading and more. Here are five key tips to consider when selecting a new bulldozer blade.

Downhill or uphill dozing direction

The dozing direction impacts the need for a rear attachment for uphill reverse travel, and may lean toward a semi U blade or full U blade on larger dozers.

Type of material 

When the blade is being used to push material such as rock, or if there are extreme conditions involved, consider using a semi U blade on a big bulldozer.

Transportation widths

Keep in mind your local regulations for transport widths; this may push buyers toward narrower blades so they can avoid having to remove the blade for every move.

Blade weight and machine balance

If you select a heavy blade on a nose-heavy tractor, you may need to look at a rear attachment to help balance the machine.

Specialty blades

If you are using rakes, clearing blades or similar attachments, these often favour a push-arm or C-frame design.
