CAT CLASS: HQ-10226

90-130 hp Dozer

The 90-130 hp dozer occupies the D4/D5 class, serving as the everyday small dozer for residential and light commercial earthmoving. Machines in this band handle building pads, driveways, and site clearing with operating weights between 12,000 and 17,180 kg and engine power from 75 to 127 hp. This size sits between the compact Up to 90 hp Dozer below and the 130-200 hp Dozer above.

Spécifications clés

Spécification	Plage typique	Signification
Engine power	75–127 hp	Defines torque and drawbar pull for pushing material and ripping hardpan.
Operating weight	26,455–37,875 lb (12,000–17,180 kg)	Determines ground pressure, traction, and the mass available for material penetration.
Blade capacity	1.5–2.5 m³ typical	Volume of material moved per pass; heavier models push larger loads.
Ground pressure	40–60 kPa typical	Lower pressure improves flotation on soft ground; varies with track width and weight.

Comment choisir

The 90-130 hp band is appropriate for residential lot grading, driveway construction, pond excavation, and light land clearing where maneuverability and moderate pushing power are both required. Machines in this class balance productivity with transportability on standard lowboy trailers. When work involves only finish grading, minimal material movement, or tight urban lots, the Up to 90 hp Dozer offers better access and lower ground disturbance. For large cut-and-fill operations, road construction, or heavy ripping in rocky soil, the 130-200 hp Dozer delivers the additional mass and horsepower necessary for efficient production.

Ce que cette taille peut gérer

Grading building pads for single-family homes and small commercial slabs
Constructing residential driveways and farm access roads
Clearing brush and light timber on 2–10 acre parcels
Excavating and shaping retention ponds and drainage swales
Spreading and compacting fill material for site preparation
Backfilling utility trenches and pipeline corridors

Sécurité et opération

Rollover protective structures (ROPS) and falling object protective structures (FOPS) are standard; operators must use seatbelts when cab or canopy is equipped with ROPS
Blade and ripper create struck-by and pinch-point hazards during maintenance; lockout/tagout procedures required before servicing hydraulics
Limited rear visibility requires spotters or camera systems when backing in congested areas or near trenches
Ground conditions must support machine weight to prevent rollovers on slopes or soft soils; maximum safe slope varies by model and typically ranges from 30% to 45%

Transport et logistique

Standard tandem-axle or tri-axle lowboy trailers handle most models in this weight class; gross combination weight typically 20,000–25,000 kg
Towing requires Class 7 or Class 8 tractor; some jurisdictions require overwidth permits for machines with wide track configurations
Ramps and hydraulic tilt decks simplify loading; machines are typically driven on and off under their own power

Alimentation

Diesel fuel consumption ranges from 8 to 15 liters per hour under typical load; on-site fuel storage or daily refueling is standard practice
Diesel exhaust fluid (DEF) required for Tier 4 Final emissions-compliant models; consumption approximately 2–5% of diesel fuel volume
Cold-weather operation may require block heaters or auxiliary starting aids in regions with temperatures below -10°C

Questions fréquentes

What differentiates a 90-130 hp dozer from smaller compact models?

The 90-130 hp class offers 50–100% more operating weight and blade capacity than sub-90 hp machines, enabling higher production rates in cut-and-fill operations and sufficient mass for effective ripping in compacted or rocky soil. The added weight requires heavier transport equipment but provides stability on slopes and in deeper cuts.

Can this size class handle land clearing with heavy timber?

Machines in the 90-130 hp range clear brush, saplings, and light timber effectively, but production drops significantly in mature hardwood forests or when felling and stacking large trees. Operations involving timber over 30 cm diameter typically benefit from the additional horsepower and weight of the 130-200 hp class or purpose-built forestry equipment.

How does track width affect performance in this horsepower range?

Wider tracks reduce ground pressure, improving flotation on wet or sandy soils and reducing rutting, but increase transport width and may require overwidth permits. Standard-gauge tracks suit most grading and earthmoving; low-ground-pressure (LGP) configurations are specified for wetlands, reclaimed sites, or fine-graded finish work where minimal surface disturbance is required.
