Mini Excavators 306 CR
$95,015.00 Original price was: $95,015.00.$59,858.99Current price is: $59,858.99.
All Day Comfort
Canopy (region dependent) or sealed, pressurised cab with improved air conditioning system, adjustable wrist rests and a suspension seat — engineered for full-day operator productivity.
Customisable Operator Settings
Programmable performance settings let operators tailor machine response to the task and their preferences — delivering the improved lift, swing, travel and multi-function gains that add up to 20% more performance.
Maximum Power in a Mini Size
The Cat C2.4 Turbo engine delivers 55.9 hp — the most powerful Cat next generation mini — with 40 gpm pump flow and 11,578 lbf bucket breakout force to handle the most demanding compact excavation work.
Fastest Swing in the Cat Mini Range
Machine swing speed of 11 rpm — 22% faster than the 304/305 CR — keeps cycle times short on mass excavation and loading tasks.
XTC Hydraulic Quick Coupler Ready
XTC carriage option enables rapid in-cab attachment changes without leaving the seat — maximising uptime when switching between buckets, thumbs, hammers and other tools.
Safety on the Job Site
Top Guard Level II, ROPS (ISO 12117-2:2008) and TOPS (ISO 12117:1997) certification provide the highest protection level in the Cat compact mini line. Courtesy work lights and fluorescent retractable seat belt included.
Simple Service for Less Downtime
Ground-level service access through side doors. Longer service intervals versus previous generation and improved fuel efficiency both reduce total cost of ownership.
Large Fuel Capacity
34.3-gallon tank — double that of the 305 CR — means fewer refuelling stops and longer uninterrupted working shifts on demanding jobs.
