How to choose the best excavator arm configuration

Skid-steer compact loader with vertical lift

With three available compact excavator arm configurations, Bobcat compact excavators cover a wide variety of digging depths, from 6 feet to more than 15.5 feet. Discover which compact excavator can accommodate your jobsite.

Standard power arm – maximum breakout force

If your priorities include digging performance, the standard arm is ideal. With enough power to tackle any job, the standard power arm on Bobcat compact excavators is the right choice for your jobsite. 

Long-arm excavator – more reach and dig depth

The longer dipper arm reaches farther from one spot to do more work without repositioning the machine. The extra reach combined with a higher dump height also makes loading trucks faster and easier.

The long-arm excavator option includes additional counterweight that enhances the compact excavator’s lifting capabilities.

Extendable arm – best of both worlds

If you need more reach, Bobcat offers the first and only clamp-ready extendable-arm option for select compact excavators. It offers the best of both worlds: power and lifting performance combined with the ability to extend the machine’s dig depth and reach when you need it.

It delivers up to 30 inches of reach at full extension (compared to standard arms), so you can reach farther with less repositioning — to dump spoil further away from the compact excavator and reach further back into the trench for cleanout purposes. Loading trucks is easier too, because the extendable arm allows you to place material more efficiently into the truck without moving the compact excavator.

The extendable-arm cylinder is powered by the primary auxiliary circuit. A roller switch on the right-hand joystick controls the extension and retraction of the Bobcat excavator arm. When equipped with a hydraulic clamp, the roller switch on the left-hand joystick controls the clamp function. Using both, it is a simple process to extend the arm and reach objects to lift and place them.

In addition, you can operate with standard reach while retaining original arm and bucket forces. The replaceable composite wear pads reinforce the excavator's structure and maintain its integrity.
