Mini Excavators 307.5 – Tier 4 / Stage V
Original price was: $126,667.00.$79,799.99Current price is: $79,799.99.
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.
