  • Operating weight 9 300 kg 20,503 lbs.
  • Blade capacity 2.13 m³ 2.79 yd³

When you need easily transportable power

When your job demands a transportable dozer that delivers power plus precise grading, the D37 may be the answer. Your operators enjoy excellent blade visibility, agility and comfort. You get versatility for construction site work, high-speed grading and more.

  • Easy to transport
  • Precision grading
  • Outstanding blade visibility
  • Agile performance with HST technology

Features and benefits

Excellent blade visibility

Your operators will love the dozer’s super-slant nose, cab-forward design that provides outstanding visibility to the cutting edges, plus excellent balance and maneuverability.

Designed to give you more uptime

You don’t need to fret about debris coming off the blade and damaging the engine cooling system. The D37’s rear-mounted cooler keeps vital engine cooling components away from the blade and is easy for your crews to maintain from ground level.

Be ready for work in small spaces

Need an agile dozer able to maneuver in tight areas and grade quickly? The D37 is designed to deliver, with variable speed option or three presets. Hydrostatic transmission eliminates steering clutches and brakes for smooth power and performance.

Steering system

Palm Command Control System (PCCS) joystick control for all directional movements. Pushing the joystick forward results in forward machine travel, while pulling it back reverses the machine. Simply tilt the joystick to the left or right to make a turn. Tilting the joystick fully to the left or right activates counter-rotation.

Hydrostatic Transmission (HST) provides smooth, powerful turns. Fully electronic control enables smooth control that can be adjusted in the monitor. The PCCS utilizes shift buttons to increase and decrease speed.

Minimum turning radius* 2.3 m

*As measured by track marks on the ground at pivot turn.
