331 Compact Excavator
A mainstay in the Bobcat compact excavator lineup, the 331 exceeds expectations with its smooth operations, fast cycle times and durable components. You are able to tow the lightweight 331 behind a one-ton truck, reach areas other machines couldn’t even imagine and work cirlces around backhoe loaders on jobsites. It has the power you need to take on jobs ranging from footing and sewer lines to retaining walls and swimming pools. Equipped with a dipper that extends hydraulically, the extendable arm version of the 331 adapts to a wide range of jobs. With the dipper retracted, it provides the same digging performance as a 331. However, extending the dipper gives you more reach and dump height to reduce repositioning for shallow digging and truck loading work. The long-arm version of the 331 lets you do more loading and shallow digging work from one spot before the need to reposition. It also offers easy access to daily maintenance items and a quiet, fuel-efficient engine. The 331 excavator is also available in a Long Arm and Extendable Arm model.
