Shantui
The SD20T-G is a wide-track (LGP) mechanical-drive crawler bulldozer purpose-built for high-mud, high-water ground such as shrimp ponds and fish farms. Nine track rollers per side, three carrier rollers and a 49-section boat-type track give an extra-long ground contact length and ultra-low 23 kPa ground pressure.
Beyond wetland duty, the machine is used for farmland reclamation, general construction and water conservancy projects, where its reinforced box-section main frame and track frame handle impact and torsion loads.
The Weichai WP9H electronic engine meets China non-road Stage IV emissions at up to 200 hp, matched to the drivetrain for balanced power, efficiency and fuel use.
The drivetrain is shared with Shantui's mechanical dozers and has a long field record. The in-house manual-shift gearbox and the high-load gears in the gearbox and final drive are made of high-strength alloy steel for long life.
The reinforced box-section main frame and track frame resist impact and torsion. Shantui-made track components, nine rollers per side, three carrier rollers and the 49-section boat-type track keep ground contact long and ground pressure very low on shrimp-pond and fish-farm ground.
The control layout is proven: steering and main-clutch levers on the left, shift/direction and blade levers on the right. The blade uses pilot hydraulics with a newly developed cross-grip lever for precise, light and sensitive control, with brake and decelerator pedals at the foot.
A spacious premium cab integrates ROPS/FOPS protection with a wide, blind-spot-free view. The air conditioner, with the evaporator and condenser mounted behind the cab, has eight adjustable vents.
A heavy-duty 3U straight-tilt blade is standard, with a wear-resistant curved cutting plate and enlarged capacity for higher pushing efficiency on all working faces.
