⚡ High Flow Hydraulics — Category Exclusive
The 309 CR is the only Cat next generation compact mini with a dedicated high flow hydraulic circuit — 37 gpm at 4,134 psi. Combined with the standard dual auxiliary circuits, total pump flow reaches 62 gpm, enabling mulchers, brushcutters, cold planers and other high-demand attachments to run at full rated performance.
All Day Comfort — Cab Standard
Sealed, pressurised cab with improved air conditioning, adjustable wrist rests and suspension seat comes standard on the 309 CR. No canopy option — designed for full-time enclosed protection in all operating environments.
Long Undercarriage for Maximum Stability
The 309 CR is built on a long (L) undercarriage — 126″ length and 97.2″ track width — delivering exceptional stability for heavy lifting, steep gradient work and high-traction pulling applications.
Widest Blade in the Cat Mini Range
97″ standard blade and 104″ wide option — the widest available across the Cat next generation compact mini line — maximise grading, backfill and site preparation efficiency.
300.7″ Maximum Reach
Matching the 308 CR’s reach envelope with the long stick — over 25 feet — for deep utility trenching, drainage works and long-reach dredging applications.
Full Safety Certification Suite
ROPS (ISO 12117-2:2008), TOPS (ISO 12117:1997) and Top Guard Level I — the complete trio. TOPS certification returns on the 309 CR after being absent on the 308 CR.
Customisable Operator Settings
Programmable performance modes tune machine response across lift, swing, travel and multi-function — delivering up to 20% more performance versus previous generation models.
Lower Owning & Operating Costs
Improved fuel efficiency, extended service intervals, load-sensing variable displacement hydraulics and ground-level side-door service access reduce total cost of ownership by up to 10%.
