Cat 306 CR excavator works on a project.
Caterpillar 306 CR compact excavator can lift up to 7,839 pounds.

The Cat 306 CR excavator is the first model in the 6-ton class. Operating weight is 15,821 pounds when equipped with a cab. Maximum dig depth is 146 inches, and tail swing is 58 inches.

The excavator can lift up to 7,839 pounds at a 9.8-foot radius. Load-sensing hydraulic system has an electronically controlled variable-displacement piston pump that generates 46 gpm flow. It can provide 24 gpm high flow to the auxiliary circuit for attachments.

A Cat C2.4 turbo diesel provides 55.9 horsepower, and auto engine idle and shutdown help conserve fuel.

Next Generation LCD monitor displays machine information including operating details such as fuel, coolant temperature, hour meter, performance and machine adjustments, and maintenance and machine monitoring.  

With the touch of a button, the operator can switch from conventional lever/foot-pedal steering controls to the standard Cat exclusive Stick Steer system. Stick Steer provides improved operator control with less effort to advance operating simplicity and comfort. For convenience, the intuitive pattern changer allows operators select their preferred joystick movement for controlling the 306 CR mini excavator.

Straight blade, angled blade and extra tool carrier (XTC) configurations further expand the flexibility of the 306 CR mini excavator. Featuring ample travel, above and below grade operation, float function, and “dig-to-blade” operation, the machine’s blade efficiently handles loose material in backfilling and grading applications. Delivering the extra precision required when digging around utilities, front shovel operation can be accomplished with both pin-on and coupler-mounted buckets.

Major machine structures—upper and lower frames, track frames, boom and stick—are modeled after its larger Cat excavator counterparts for long-term durability. Recessed to protect from damage in the field, flat side panels offer long service life and quick, easy replacement to lower owning and operating costs.

Ground-level access to maintenance checkpoints offers convenient access, while enhancing worker safety.
