Description
The Case 1550 Dozer is a top-tier crawler dozer engineered for large-scale earthmoving, grading, and land clearing projects. With its Case 6T-830 turbo diesel engine producing 150 net horsepower, this machine delivers robust performance in even the most challenging terrain.
A hydrostatic transmission provides smooth, variable-speed control, while a closed-center, load-sensing hydraulic system allows for high-efficiency blade responsiveness under varying load demands. Combined with a 10-foot wide blade and exceptional pushing power, the 1550 is ideal for contractors, land developers, and heavy construction professionals.
