Overview
The D37PX-24 is a transportable crawler dozer designed for precise grading, high agility and clear blade visibility. Suited for construction site work, high-speed grading and confined-space operations, it combines hydrostatic transmission responsiveness with a cab-forward slant-nose layout for operator control and visibility.

Key specifications (high-level)

• Power: 66 kW (89 HP) @ 2,200 rpm
• Operating weight: 9,300 kg (20,503 lbs)
• Blade capacity: 2.13 m3 (2.79 yd3)
• Shoe width (standard): 600 mm single-grouser shoe
• Maximum travel speed: up to 13.7 kph (8.5 mph) in highest quick-shift

Features and benefits

• Excellent blade visibility — Super-slant nose and cab-forward design provide clear sightlines to cutting edges for accurate grading and safer operation.
• Designed for uptime — Rear-mounted cooler and accessible service points reduce debris exposure and simplify maintenance from ground level.
• Compact agility — Hydrostatic transmission (HST) and variable speed or preset quick-shift settings enable precise maneuvering and fast grading in tight areas.
