Used Cat 306 Excavator Series

The Cat 306 CR is a solid all-around choice when you need a machine that’s both compact and capable. Its small footprint makes it easy to work in tight or crowded areas—whether that’s a residential job, a roadside site, or a utility trench.

But don’t let the size fool you. It delivers strong performance, with enough power to handle demanding digging, lifting, and grading tasks without slowing you down.

Operators usually get comfortable with it fast. The controls are straightforward, and you can adjust settings based on personal preferences, which is helpful when more than one person’s running the machine.

Whether it’s your first mini excavator or an addition to a growing fleet, the 306 CR does a little bit of everything—and does it well.

Caterpillar clearly kept the operator in mind when building the Cat 306 CR. The cab is quiet, comfortable, and well laid out, with adjustable controls and an upgraded air conditioning system that actually holds up on hot days.

Whether you’re in the seat for a few hours or running a full shift, it’s built to reduce fatigue and make the work more manageable.

On the safety side, it includes smart, practical features like fluorescent step markings, courtesy work lights, and an optional rear-view camera — all small things that make a big difference in busy or low-light job sites. It’s the kind of attention to detail that helps crews work with more confidence.

The 306 CR also keeps costs in check. With efficient hydraulics, auto idle, and an easy-to-service layout, it’s designed to run lean and stay on the job.

For contractors looking for dependable performance without the high operating overhead, this machine checks all the right boxes.
