Komatsu D61-24 Dozer has 20 Speed Transmission

The D61-24 crawler dozer has a quick-shift, three-speed mode and a variable, 20-speed customizable transmission mode. It has a 168-horsepower, SAA4D107E-3 Tier 4-Final engine. More than 99 percent of Komatsu Diesel Particulate Filter regeneration is performed with no action required by the operator, according to the company.

Operating weight is 38,647 pounds.

The H-mode function on the dozer, which allows it to maintain speed when a heavy load would normally bog down the engine, now has fast-blade capability. It ensures the blade adjustments needed to keep a full load on the blade keep pace at higher speeds, thus maximizing production, the company says.
