Features

No blade mounted GNSS antenna(s), cables to worry about damaging with cab top GNSS antenna. Reduced risk of theft due to low visibility as viewed from ground level.
 

The D51EXi PAT high-capacity (4.4 yd3), high wear-resistant blade can increase production.
 

Production increased by up to 15%

The D51EXi-24 is equipped with Komatsu-designed HST that allows for Quick-Shift or variable speed selection. The HST consists of dual-path closed-circuits, with two variable displacement piston pumps and two variable displacement travel motors. Hydrostatic steering eliminates steering clutches and brakes, providing smooth, powerful turns. Fully electronic control provides complete automatic shifting and enables smooth control. Engine speed is controlled using an electronic fuel control dial.
 

SAA4D107E-3 EPA Tier 4 Final emissions certified engine has a water cooled variable geometry turbocharged and aftercooled 4.5 liter diesel engine which provides up to 13% increased fuel efficiency.
 

Komatsu's PLUS rotating bush design provides less downtime, longer wear, and with up to 40% lower undercarriage maintenance costs, than conventional undercarriage. Rotating bushings eliminate the cost and downtime for bushing turns, and strengthened rollers and links increase wear life up to two times. With PLUS, individual links can be replaced with common track tools.
 

A high wear-resistant power angle, power tilt dozer blade with adjustable blade pitch is available on the D51EXi-24. The hydraulic blade tilt and angling function expands versatility and productivity in a variety of applications.
 

Robust stroke sensing hydraulic cylinders employ proven Komatsu sensor technologies for accurate finish grade performance. Stroke sensing angle cylinder allows machine control system to know the angle of the blade.
 

The D51EXi-24 utilizes a swing-up fan with a gas strut-assisted lift system to provide easy access to the (side-by-side) radiator, oil cooler and charge air cooler. The hydraulic fan is reversible to help keep the radiator cores clean and simplify maintenance.
 

The D51EXi-24 incorporates Komatsu's superslant nose design. Komatsu's innovative design provides excellent blade visibility for improved machine control and increased efficiency and productivity.
