Bobcat Clamshell buckets are designed with the revolutionary HPXdrive® and therefore have no exposed hydraulic cylinders, bushings or pins. The powerful drive system generates a constant closing force, making your work easier and more efficient. Infinite rotation comes as standard. The hydraulic connection of the swivel and HPXdrive® is direct, requiring no hoses. To maximise uptime, HPXdrive® clamshell buckets are completely maintenance-free.
