Reliable earthmoving power for every job

Dozers are the backbone of earthmoving—pushing, grading, and shaping material on construction, mining, forestry, and pipeline projects. With the right blade, undercarriage, and spec, a bulldozer delivers the traction and control crews rely on to keep production moving.

Across our equipment auctions, you’ll find a wide range of crawler and wheel dozers from leading brands, with configurations to match your site conditions and workload.

Common bulldozer applications

Dozers, are used anywhere heavy material needs to be pushed, leveled, or cleared. In construction, they handle site preparation, grading, and backfilling. Mining and quarrying operations use dozers to maintain haul roads, move overburden, and manage stockpiles. In forestry and land clearing, they remove brush, stumps, and debris with the help of rippers or PAT blades. Dozers also play a key role in pipeline and roadbuilding projects, cutting and filling material, shaping slopes, and maintaining rights-of-way. In waste management and land reclamation, they spread, compact, and reshape material to keep sites productive and compliant.

Types of dozers

Crawler dozers

Tracked dozers are the industry standard for traction, slope work, and soft or uneven ground. They balance pushing power with precise control for site prep, cut-to-fill, and finish grading.Explore crawler dozers

Wheel dozers

Wheel dozers combine high production with faster travel for large, firm worksites—common on mines, stockpiles, and cleanup where mobility between tasks matters. They’re a strong fit when speed and long pushes on hard surfaces are priorities. Explore wheel dozers.

Size classes

Dozers are commonly grouped as small, medium, and large. Choosing the right class comes down to material, push distance, site conditions, and transport needs. Use this page as a high-level guide, then dive into child pages for detailed model-level specs.

Blades and rippers

  • S (straight) blade — A straight moldboard with no wings for precise cutting and trimming; favored for finish work and hard material.
  • U (universal) blade — Tall, curved moldboard with large wings to carry more material efficiently over distance.
  • SU (semi-universal) blade — A versatile middle ground: more carry than an S-blade with better control than a full U-blade; a common “do-most” choice.
  • Angle blade — Pivots left/right to windrow and side-cast; useful for road building, drainage, and snow/cleanup tasks.
  • PAT/VPAT (6-way) blade — Power angle and tilt for finish grading, slopes, and tight areas; popular where versatility and surface quality are critical.

Rear equipment like single-/multi-shank rippers or a winch expands a dozer’s capabilities for site clearing, rock breaking, or pulling tasks. If you're desired dozer doesn't have the necessary attachemnts you require, browse our wide slection of dozer blades, rakes and rippers.

Undercarriage & tracks

The undercarriage is a major operating-cost driver on crawler dozers. Track shoes, rollers, idlers, and sprockets all wear with travel and ground conditions, so selection and maintenance matter. Many models are offered in LGP (low ground pressure) configurations with wider shoes and frames to spread weight for better flotation on soft ground. Choose LGP for mud, peat, or sand; choose standard or narrow shoes for abrasive or rocky sites where durability and maneuverability take priority.

Specs that matter

  • Operating weight & horsepower — Match push power and stability to site size and material.
  • Blade width & capacity — Impacts cycle efficiency, carry distance, and finish quality.
  • Ground pressure — Critical for soft soils and environmental sensitivity; LGP packages reduce psi on the ground.
  • Transport width — Check permitting and trailering requirements, especially on larger classes or wide-shoe LGP builds.

Popular brands you’ll find with us

Look for well-known families and series from Caterpillar, Komatsu, John Deere, CASE, and Liebherr across small, medium, and large classes. Availability varies by auction—browse current lots for the latest selection.

Buying used: What to look for

  • Undercarriage condition — % remaining on chain, rollers, idlers, and shoes; even wear patterns.
  • Blade, pins & bushings — Excess play and cutting-edge wear affect grading quality.
  • Frame & structure — Check for repairs, cracks, or twist from heavy pushing.
  • Hydraulics & powertrain — Smooth control response; evaluate for leaks, noises, or fault codes.
  • Hours & service history — Oil samples, maintenance records, and component rebuilds help predict costs.

Common dozer FAQs

What’s the difference between a crawler dozer and a wheel dozer?

Crawler dozers use tracks for traction, stability, and grading on soft or uneven ground. Wheel dozers travel faster on firm, open worksites and are common for cleanup, stockpiles, and long pushes on hard surfaces.

What does LGP mean on a dozer?

“Low ground pressure.” LGP configurations use wider shoes and frames to spread machine weight, improving flotation in mud, peat, or sand while reducing sinkage and ground disturbance.

Which blade should I choose?

S for precise cutting, U for maximum carry, SU for balanced general dozing, angle for windrowing/side-casting, and PAT/VPAT for versatile finish grading and slope work.

How much does a bulldozer weigh?

It varies by class and configuration. As examples, mid-size models often list operating weights around 18–23 metric tonnes, while large units can exceed 40 tonnes. Always confirm the specific machine’s spec sheet.
