Among Bobcat's conventional utility vehicles are the 2100 and 2100S, available in a 4×2 configuration, and the 2200, a 4×4 model with a choice of gas or diesel engines. But Bobcat's big gun is the 5600 B-Series Toolcat, a "utility work machine" that uses a 46-hp Kubota diesel engine, or an optional turbocharged Kubota that delivers 56 horsepower. The four-wheel-drive, four-wheel-steer Toolcat is designed to handle a broad range of attachments and has a standard auxiliary hydraulic system that provides flows up to 18 gpm. A high-flow option delivers 26 gpm. The Toolcat's two-speed, hydrostatic drive system allows speeds to 18 mph, which can be maintained via a cruise-control feature.
