Cat 306 CR and 307.5: clearance, weight and attachment supply

306 CR or 307.5: compare the space around the machine

The 306 CR has a compact-radius rear body and a boom that swings left or right independently of the house. The 307.5 dimensional sheet instead describes its conventional rear swing and front arrangement. Neither model's digging depth tells you the space needed beside a wall.

The 306 CR drawing separates its boom-swing dimensions from house width; a 307.5 clearance check must account for the counterweight's sweep.

Counterweight selection changes that sweep. The December 2025 306 CR brochure shows separate tail radii without additional counterweight and with either of its counterweight options. The September 2024 307.5 sheet likewise separates the with- and without-counterweight dimensions.

Establish the fitted weight before applying a tail-radius figure. Both dimension tables also distinguish a standard stick from a long stick, so reach, dump clearance and transport posture should come from the same column.

Attachment flow and the cost of a longer stick

The 307.5 primary auxiliary specification is higher than the 306 CR's, but the pump total is a different quantity from the auxiliary branch. Cat explicitly warns on the 307.5 sheet that maximum flow and pressure cannot be combined: available pressure falls as flow rises under load. Multiplying both maxima would imply an attachment output that the document does not promise.

A long stick offers reach while reducing stick digging force. Cat lists that trade-off separately for each excavator. Extra reach also adds mass: the 307.5 long-stick option has a larger listed weight increment than the 306 CR option.

A transport calculation needs the installed stick, tracks, blade and counterweight, then the actual bucket or coupler; the brochure's minimum and maximum operating-weight descriptions exclude the bucket.

Sources: 306 CR configured weights and hydraulics; 307.5 branch flow, digging forces and weight assumptions.

Identify controls and software on the actual unit

Stick Steer changes travel from pedals and levers to joystick control at a button press. Travel cruise is another function; neither feature is an automatic grading system. The Indicate package shows the bucket's position relative to a selected grade.

Cat says it does not automatically reposition the boom, stick or bucket. E-Fence constrains movement within the operator's selected boundaries, while Grade automatics require their own equipment.

Publication differences matter for the 306 CR. The December 2025 brochure names C2.4 in its engine specification but C1.7 in its equipment list; its configured weight range also differs from Cat's current product-page range. Those conflicting entries remain identified by source.

Use the machine's engine plate and build documentation to resolve them before ordering parts or assigning a transport mass.
