Komatsu small dozers are great finish grading tractors for a lot of reasons but the most obvious is the super slant nose design. The super slant nose design moves the coolers and hydraulic fan to the rear and the operator forward to create a balance that makes fine grading with or without a grade control system a breeze. A fully hydrostatic drivetrain gives the operator incredibly quick and precise maneuverability. And new Power and Economy working modes allow the operator to adjust his machine’s performance to his current job and save on fuel consumption as he’s doing it. Like all Komatsu products, the D37EX-23 has the advanced hydraulics to make the addition of a grade control system seamless and turn it from a great grading tractor to an incredibly precise and fast fine grading system.
