The hydrostatic system in HopTop D200HS bulldozer simplifies the power transmission route. In addition to featuring the high-position drive structure found on standard models, it is equipped with widened track shoes, enabling it to operate efficiently even on soft, muddy terrain.
Featuring the classic elevated sprocket design (high-drive structure), the tracks of the D200HS are arranged in a distinctive triangular layout.With an operating weight of 21.4T, this specialized swamp bulldozer is powered by the high-performance SC7H210.1G3 engine, delivering a rated power of 155kw@2000rpm. It features a highly efficient, dual-path hydrostatic transmission (HST) system with a multi-pump and multi-motor closed-loop hydrostatic setup. By completely eliminating the need for a torque converter, traditional gearbox, and steering clutches, the drive system operates with zero mechanical wear and exceptional reliability, automatically adapting speed and torque to load variations.
The D200HS is specifically engineered for extremely soft, muddy, and treacherous terrains. It serves as an indispensable solution for wetland reclamation, swamp dredging, delta mudflat operations, pond fishpond construction, and soft soil infrastructure projects. Its low ground pressure design ensures the machine operates continuously where standard tractors would easily bog down.
Delivering outstanding maneuverability, the D200HS wetland dozer moves rapidly across loose grounds. It comes standard with a specialized wetland straight-tilt blade featuring an optimized wide-dimension design to efficiently scrape and move large volumes of soft mud and silt. Crucially, the machine is fitted with extra-wide triangular wetland track pads, which drastically reduce ground bearing pressure and provide fierce flotation, perfectly preventing the machine from sinking or slipping in deep marshes and bogs.
Engineered for excellent fuel economy, the engine of the D200HS maintains a constant operating speed regardless of the actual travel speed, effectively eliminating unnecessary fuel consumption.
The premium operator environment features a spacious cab with large glass areas for panoramic visibility. It comes standard with an integrated ROPS/FOPS (Roll-Over/Falling Object Protective Structure) for maximum safety. Both the travel and implement systems are managed via single-joystick electronic controls, ensuring simple, comfortable, and precise operation. Additionally, high-efficiency soundproofing structures guarantee low interior noise, while the fully adjustable suspension seat provides an ergonomic and fatigue-free working environment for the driver.
