Bobcat S630 and S650

As the first of Bobcat's M-Series loaders, the S630 and S650 skid steer loaders and T630 and T650 compact track loaders incorporate a numbering system new to the Bobcat product offering. After the S and T designations for skid steers and track loaders respectively, the first number designates the frame size, and the remaining numbers indicate performance based on a cross-section of factors. For instance, an S630 and S650 have similar frame sizes and horsepower, but the S650 has higher weight and rated operating capacity due to its vertical lift arm path arrangement. With the M-Series loaders, a more spacious, cab-forward design features improved visibility and comfort for the operator. A claimed 15-percent-plus hydraulic horsepower increase boosts attachment performance.
