Dozer Blades: Types of Dozer Blades
Not every blade is built for the same job. Matching the blade to your application (material type, push distance, slope, grading precision) is the difference between efficient production and your operator fighting the machine all day. Selecting the proper blade significantly improves efficiency while reducing unnecessary wear on the machine. Here’s a breakdown of the most common dozer blade types and their configurations.
Common dozer blade types include:
- Straight Blade (S-Blade)
- Universal Blade (U-Blade)
- Semi-Universal Blade (SU-Blade)
- Power Angle Tilt (PAT) Blade
- Angle Blade (A-Blade)
- Specialty Blades
Straight Blade (S-Blade)
Straight blades are shorter and flatter than other blade styles with a straight profile and no side wings. That design limits carrying capacity but gives the operator a high degree of control and good penetration. Crawler dozers pair well with the S-blade where precise traction, maneuverability, and precision matter more than bulk volume.
Common applications for S-blades include:
- Fine grading
- Leveling
- Backfilling
- Shaping cuts
- Stumping
- Ditching in medium-to-hard materials
- Short-distance pushing
- Finished surface preparation
- Light material movement
Universal Blade (U-Blade)
Universal blades feature tall side wings and a curved profile that helps retain large volumes of material. They are designed for maximum carrying capacity and efficient material transport over longer push distances. Its tall, curved profile and large side wings cradle loose material and keep loads contained on the blade.
Common applications for U-blades include:
- Moving soft soil or bulk fill over distance
- Landfill operations
- Mining
- Large-scale earthmoving
- Coal handling
- Stockpile work
- Mass excavation
Semi-Universal Blade (SU-Blade)
The Semi-Universal blade combine the characteristics of straight blades and universal blades. It has a shallow curve and shorter side wings, which means less raw volume than a full U-blade but more penetration strength and maneuverability. They provide improved carrying capacity while maintaining good penetration and control.
Common applications for SU-blades include:
- General construction
- Road building
- Bulk earthmoving
- Quarry work
- Heavy production applications
Power Angle Tilt (PAT) Blade
The PAT blade offers the most operator control of any blade configuration. Hydraulic controls allow simultaneous tilting, angling, and lifting in all directions. It’s the preferred setup for detailed finish grading, land clearing, and working on complex or uneven terrain where constant blade adjustments are needed. These blade configurations are most commonly found on smaller dozers where precision work drives the job.
Common applications for PAT-blades include:
- Finish grading
- Slope shaping
- Landscaping
- Utility projects
- Precision dirt work
Angle Blade (A-Blade)
Angle blades are designed to direct material to one side during operation. The angle blade mounts centrally and adjusts up to 30 degrees left or right, making it the go-to for side casting, ditching, road shaping, and snow removal. It’s thinner than other blade types, fits tighter working areas, and uses a replaceable cutting edge that simplifies maintenance. Because of its adjustability, the angle blade handles soft, medium, and hard ground conditions and moves material effectively in either direction.
Specialty Blades
For specific applications, specialized blade configurations are available. Coal and large-capacity blades feature a taller, higher-volume profile designed for pushing lightweight, loose material like coal or wood chips. Cushion blades are built for dozer-to-dozer push operations (the blade’s shock-absorbing design protects both machines during contact). If your operation calls for a specialty blade, EquipXR’s part experts will find the right blade components and wear parts for your dozer’s application.
Complete Dozer Blade Assemblies
A complete blade system includes structural, mounting, pivoting, and control components that work together to transfer pushing force from the machine to the material. EquipXR offers everything from complete blade assemblies to structural and mounting components that keep the blade securely connected to the machine.
A complete replacement blade may be needed when the existing blade has extensive structural wear, severe damage, cracking, bending, or previous repairs that make another rebuild impractical. Depending on the machine and configuration, complete blades, blade shells, moldboards, and related assemblies may be available. EquipXR will identify replacement blade options based on your dozer model, serial number, and existing blade configuration.
Blade Moldboards
The moldboard forms the main curved surface of the dozer blade. Its shape helps control how material rolls, carries, and moves in front of the machine. Replacement moldboards, face plates, reinforcement plates, and repair components are available for compatible blade assemblies. Replacement moldboards and related structural blade components are used when rebuilding a damaged or heavily worn blade.
Push Arms & C-Frames
Push arms connect the blade assembly to the dozer and transfer pushing forces back into the machine. Because these components operate under heavy loads, worn mounting points, bent arms, cracking, and damaged bushings affect blade alignment and stability. EquipXR offers replacement push arms and related mounting components for many crawler dozer models.
C-frames support the blade on many angle, PAT, and six-way blade configurations. Wear develops around pivot points, mounting locations, pin bores, and other high-load areas. A worn or damaged C-frame will lead to excessive blade movement and poor blade control. Replacement C-frames, frame components, pins, bushings, mounting parts, and related hardware are available for many dozer applications.
Blade Tilt & Lift Components
The blade lift and tilt system allows the operator to control blade height and position while working. This movement control is important for slope work, ditching, grading, and shaping terrain. Depending on the dozer and blade design, the assembly includes mounting brackets, linkages, pivot points, pins, bushings, hydraulic cylinder mounting components, and related hardware.
Hydraulic cylinders control blade lift, tilt, and angle functions. Leaks, damaged rods, worn seals, and internal hydraulic issues reduce blade responsiveness and operating precision. EquipXR supplies dozer hydraulic replacement parts for many major dozer platforms.
Blade Trunnion, Pins, and Bushings
Trunnions provide heavy-duty pivot and mounting points between the blade, push arms, and machine. Constant movement under load gradually wears the trunnion surface and surrounding mounting components. Pins and bushings are used throughout the blade mounting and linkage system. These components allow joints to pivot while keeping the blade properly positioned. As these components wear, clearances increase and the blade develops excessive movement. Replacing worn trunnions, pins, and bushings restores tighter blade movement while protecting larger and more expensive structural components.
Ground Engaging Tools (G.E.T.)
The blade assembly does the pushing, but the ground-engaging tools take the direct wear from dirt, rock, gravel, and other abrasive materials. These replaceable wear components help protect more expensive blade, ripper, and attachment components from direct abrasion and impact.
EquipXR supplies aftermarket dozer ground engaging tools (G.E.T.) designed to protect your blade and maintain effective digging and pushing performance. Our dozer ground-engaging tool selection includes cutting edges, end bits, corner bits, blade protectors, wear components, ripper tips, ripper shanks, shank protectors, pins, retainers, and other replacement G.E.T. for popular dozer makes and models.
Choosing the right G.E.T. depends on your dozer, attachment, material conditions, and application. Visit our dozer ground engaging tools page to explore replacement wear parts, or send us your machine model, serial number, and OEM part number to find the parts you need.

Blade Part Compatibility by OEM Brand & Model
An OEM part number is one of the best pieces of information to provide when requesting a replacement dozer part. EquipXR uses OEM reference numbers to cross-check available aftermarket replacements and verify the intended application. This is particularly useful when working with older equipment or machines that have several possible blade configurations. If you’re not sure which blade assembly best fits your machine or application, our team will work with you directly to confirm compatibility during the quoting or ordering process.
| OEM | Model Series | Blade Types |
|---|---|---|
| Caterpillar | D3, D4, D5 | 6-Way, PAT, Angle, Semi-U |
| Caterpillar | D6, D6T, D6R | Straight, PAT, Semi-U, Full-U |
| Caterpillar | D7, D8, D9, D10, D11 | Straight, Semi-U, Full-U, Coal/Push |
| Komatsu | D37, D39 | 6-Way, S-Blade, PAT |

| Liebherr | PR 714, PR 724, PR 734 | Straight, Semi-U |
A note on variant confirmations: Model series alone doesn’t always determine the right part. Generation, year of release, blade series, and any factory blade-width modifications all affect what parts fit your equipment. When in doubt, pull the blade serial number or cross-reference your OEM parts manual, and reach out to our team for a cross-reference match.
Blade Dimensions & Mounting Configuration
Dozer blades are built in different widths, heights, capacities, and mounting configurations depending on the machine and application. Even two dozers from the same model series may use different blade arrangements, so matching the replacement blade or blade component to the specific machine is important.
Key blade specifications include overall blade width, blade height, moldboard curvature, mounting-point locations, pin diameters, push-arm configuration, and lift and tilt mounting locations. Blade width and height affect the amount of material the machine pushes and the overall working width. The moldboard profile and curvature influence how material rolls and carries across the face of the blade. Dimensions vary depending on whether the machine uses an S-blade, SU-blade, U-blade, PAT blade, angle blade, or another configuration.
When sourcing a replacement dozer blade or major blade component, provide the manufacturer, model, serial number, blade type, and OEM part number when available. EquipXR uses this information to help match aftermarket dozer blades and replacement components to your machine. Photos of the blade, mounting points, damaged component, and any visible identification numbers also help with parts identification.
Frequently Asked Questions
An S-blade (straight blade) has no side wings and a flat profile, whereas a U-blade has a deep curved face and tall side wings. The SU-blade (semi-universal) is the middle ground option: modest wings and a slight curve, versatile enough for mixed-condition work without specializing in either direction.
Common dozer blade types include straight blades (S-blades), universal blades (U-blades), semi-universal blades (SU-blades), angle blades, Power Angle Tilt (PAT) blades, and six-way blades. Larger or specialized machines may also use coal, landfill, forestry, and other application-specific blades.
Yes, many dozer blades can be rebuilt if the main structural components remain serviceable. A rebuild may involve replacing pins, bushings, trunnions, wear plates, mounting components, push arms, hardware, or other damaged parts. Severe cracking, deformation, or structural wear may make complete blade replacement more practical.
A dozer blade can often be repaired when the damage is limited to replaceable wear parts or isolated areas of the assembly. Worn cutting edges, end bits, pins, bushings, minor cracks, and localized damage may be repairable if the moldboard, push arms, mounting points, and overall blade structure remain in good condition. Uneven cutting edges, excessive movement at the blade connections, visible cracks, difficulty maintaining grade, or a blade that no longer sits square are signs that the entire assembly should be inspected.
Replacement may be the better option when the moldboard is severely worn, bent, cracked, or structurally weakened, or when pinholes, blade arms, mounting points, and other major components have extensive wear. The age and overall condition of the dozer should also factor into the decision, especially when comparing the cost of repeated repairs with a replacement blade. When evaluating a replacement, inspect the condition of the pinholes, edges, corners, moldboard, blade arms, and hydraulic components. Construction Equipment provides additional guidance on what to consider when replacing a dozer blade.
Uneven wear results from the type of work being performed, frequent operation with the blade tilted or angled, worn mounting components, improper blade alignment, damaged structural parts, or operating consistently on one side of the machine.
To fix uneven blade wear, first inspect the blade assembly for excessive play, bent or damaged components, and worn pins, bushings, mounts, and trunnions. Check that the blade is properly aligned and that the lift, tilt, and angle systems are operating correctly. Worn components should be replaced before they cause additional damage. If the uneven wear is limited to the cutting edge, replacing or rotating a reversible cutting edge may restore an even working surface. Efficient operator practices also help prevent the problem from returning by reducing unnecessary one-sided loading and alternating blade positions when the application allows.
