  • Engineered for exceptional versatility and high-efficiency earthmoving, the D550H hydrostatic bulldozer features a high-performance, VOLVO PENTA TAD1650VE-B turbocharged engine combined with an advanced dual-path hydrostatic transmission (HST) system. This closed-loop hydrostatic setup automatically balances speed and torque under changing loads, eliminating the need for traditional gearboxes and torque converters, ensuring seamless power transfer and outstanding fuel economy.
  • The advanced travel control system allows the D550H to achieve counter-rotation, power turns, and infinitely variable speed control. The hydraulic-assisted steering and single-joystick electronic control deliver effortless, ultra-precise maneuverability, dramatically reducing operator fatigue while maximizing site productivity.
  • Equipped with a standard high-capacity straight-tilt blade, the D550H track-type tractor offers formidable cutting force and optimized tilting performance for precision grading and heavy-duty pushing. At the rear, it can be configured with an optional three-shank ripper or single-shank ripper, allowing it to effortlessly penetrate and loosen hard clay, frozen soil, and compacted materials. Built on a rugged, durable undercarriage system, it ensures long-lasting reliability across harsh terrains.
  • The premium operator cabin is designed with an integrated ROPS/FOPS structure for maximum safety. It features a spacious interior, panoramic visibility, and high-efficiency soundproofing to guarantee a low-noise, dust-free working environment. For user-friendly maintenance, the D550H integrates a wide-opening engine hood and centralized electrical control, alongside centralized pressure measurement points, making routine inspection and servicing exceptionally convenient.
  • This versatile earthmoving machinery is perfectly suited for road building, infrastructure projects, mining, and landscaping, making the D550H an indispensable piece of heavy equipment for global construction challenges.
