Komatsu makes the world's largest dozer which has over 1000 horsepower, and on the other end makes one of the cutest little ones as well. The D20 is just about the right size for landscaping a small yard. With rubber tracks you can drive it across the sidewalk to get there and not tear anything up. The rubber tracks are neither as durable nor do they provide as much traction as classic iron tracks, but the ability to work on paved surfaces is the trade off. Either rubber or steel tracks are available for this machine.
The transmission is manual with a Johnson bar for quick reversal. Steering is accomplished with combination steering clutch/brake hand levers. The engine is a small diesel. The Blade is a PAT (power angle tilt). This is a snoosie little dozer with horsepower in the range of 35. It will spin the tracks in about 3 speeds forward.
