Up to 150 hp Motor Grader
Up to 150 hp motor graders represent the compact end of the grading spectrum, typically equipped with 12-foot blades and diesel engines ranging from small utility units up to 147.5 hp. This size class handles gravel road maintenance, subdivision street finishing, and site work where maneuverability and lower operating weight matter more than production rate. Above this band, 150-200 hp Motor Grader machines offer greater blade capacity and articulation for larger-scale road construction.

Especificaciones clave
| Especificación | Rango típico | Qué significa |
|---|---|---|
| Engine power | 1.5–147.5 hp | Power range spans small utility graders to full-sized 12 ft blade machines; upper limit defines this compact grader class. |
| Operating weight | 22.7–39,683 lb (10.3–18,000 kg) | Weight range spans utility graders to full-sized 12 ft machines; heavier units provide better blade penetration and stability. |
| Fuel tank capacity | 2.0–43.0 gallons | Smaller tanks on utility models; larger machines typically carry 30–43 gallons for extended shifts. |
| Transport speed | 3.3–15.0 mph | Road travel capability for moving between job sites or along maintenance routes without hauling. |
Cómo elegir
Up to 150 hp motor graders are specified for gravel road maintenance, subdivision finish grading, and municipal street work where a 12 ft blade and compact footprint are adequate. This size excels in confined sites, residential streets, and applications requiring frequent relocation between smaller work areas. For state highway construction, large-scale earthmoving, or cuts exceeding 12 feet, the 150-200 hp Motor Grader class provides the blade length, articulation geometry, and horsepower needed for production grading. Projects involving only occasional spot grading may be better served by towed box blades or smaller tractor attachments, though those lack the precision and independent blade control of a dedicated motor grader.
Lo que maneja este tamaño
- Maintaining gravel county roads and culvert approaches
- Finish grading subdivision streets and cul-de-sacs before paving
- Shaping drainage ditches and roadside shoulders
- Site cleanup and pad leveling on residential developments
- Municipal parking lot base preparation and grading
- Light snow removal and winter road maintenance
Seguridad y operación
- Blade and scarifier positioning require clear zones; bystanders must remain outside the turning radius and blade swing path.
- Articulated steering geometry creates rear-wheel offset during turns; tail swing and wheel tracking differ from rigid-frame equipment.
- Operators must verify overhead clearance when raising the blade or moldboard for transport or repositioning.
- Sloped or cambered surfaces require attention to rollover geometry; lower ground clearance and narrow wheelbases increase risk on severe cross-slopes.
Transporte y logística
- Lighter models (under 8,000 kg) typically move on tandem-axle tagalong trailers; heavier units require gooseneck or lowboy trailers rated for 18,000+ kg.
- Many units in this class are driven short distances on public roads at 10–15 mph, avoiding trailer transport for nearby jobs.
- Loading requires 16,000–20,000 lb capacity ramps or tilt-bed trailers; blade must be centered and raised for safe transport.
Alimentación
- Diesel fuel supply on site or nearby fueling runs; 30–40 gallon tanks typically support 8–10 hour shifts at moderate load.
- Cold-weather operation may require diesel fuel treatment or winter-blend fuel to prevent gelling.
- No external electrical power required; all systems run from the engine-driven hydraulic and electrical systems.
