Komatsu D51EXi-24 Crawler Dozer

Komatsu D51EXi-24 dozer

Intelligent Machine Control machines have the following advantages over dozers with external grade control systems:


No coiled cables between machine and blade
Automated operation from rough dozing to finish grade
No Climbing
GNSS antenna and mast removed from blade
New dozing mode, load control performance features
No Connections
No daily connections required between machine and blade Integrated
Standard factory installed integrated system


• Automated Blade Control, from Rough Dozing to Finish Grade. Straight to Grade. Blade moves to target surface until load reaches a preset level.
The blade automatically raises to minimize track slip. Should the load decrease, blade will lower to re-load blade to an optimum level.

Cab Top GNSS Antenna
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.

Stroke Sensing Hydraulic Cylinders: 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.

Komatsu’s New Emission Regulations-compliant Engine: 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.
