Key Benefits & Features

All Day Comfort — Cab Standard

A sealed, pressurised cab with improved air conditioning system, adjustable wrist rests and a suspension seat comes standard on the 307.5 — no canopy option. Built for operators who need full-day protection in any conditions.

Highest System Pressure in the Cat Mini Range

4,134 psi equipment and travel pressure — the highest in the Cat next generation compact mini line — delivers maximum force for the most demanding excavation, lifting and attachment work.

Customisable Operator Settings

Programmable performance settings let operators tailor machine response across lift, swing, travel and multi-function tasks — delivering up to 20% more performance over previous generation.

Widest Dozer Blade in the Range

90″ wide blade — 12″ wider than the 306 CR — moves more material per pass, speeds up backfilling and delivers cleaner site preparation on wider cut areas.

Big Reach — 267.9″ Maximum

182.8″ dig depth and 267.9″ maximum reach with the long stick put the 307.5 in a different league for deep utility trenching, drainage works and large-scale landscaping.

Safety on the Job Site

ROPS (ISO 12117-2:2008), TOPS (ISO 12117:1997) and Top Guard Level I certification — plus courtesy work lights and fluorescent retractable seat belt — standard on every machine.

Lower Owning & Operating Costs

Improved fuel efficiency, longer service intervals, and load-sensing variable displacement hydraulics all reduce daily running costs. Ground-level service access through side doors keeps planned maintenance fast.

Large Fuel Capacity

38-gallon tank — the largest in the Cat compact mini range — minimises refuelling interruptions on full-day and multi-shift operations.
