CAT 277B – Multi Terrain / Compact Track Loader

The Caterpillar 277B is a rubber-tracked multi terrain loader / compact track loader designed for high productivity on soft, muddy or finished surfaces where low ground pressure is important. It uses a radial-lift boom for strong digging and loading performance, and the ASV undercarriage with rubber tracks provides excellent flotation and traction while minimizing damage to ground surfaces. Powered by a turbocharged Cat diesel, the 277B is widely used in construction, landscaping, civil works and material-handling applications where a wheeled skid steer would struggle.
