Komatsu D21S-5 overview

Hydraulic system

Large Bucket

With capacity larger than that of standard buckets, the large bucket carries and loads large volume of soil of light specific gravity.


Side-Dump Bucket

In addition to regular forward dumping, the side-dump bucket can dump to the right or left, thereby increasing the machine's versatility. The hydraulic cylinder tilts the bucket side-ways.


Multi-Purpose Bucket

A bucket/blade combination usable as a bucket, blade, scraper or clamshell for all-around loading, topsoil stripping, bulldozing and debris-cleaning.


Work tools

Multi-shank ripper

Steel tips of shanks heat-treated for extra rigidity and durability. Machine weight and hydraulic force combine to give ripper great digging/pulling force.


Towing winch

For pulling, lifting and lowering materials of medium and heavy weight. Automatically unwinds and slackens wire or other cables.
