The largest and most capable Cat next generation mini excavator — delivering the highest bucket force, deepest dig depth and greatest reach in the Cat compact excavator lineup. ▶ Next Generation · C3.3B · 17,459 lbf Bucket · 205.2″ Deep · 303″ Reach 69.5 hp Net Power 23,002 lb Max Op. Weight 205.2“ Dig Depth ★ Range Max 303“ Max Reach ★ Range Max 17,459 lbf Bucket Force ★ Range Max 62 gpm Pump Flow 4,134 psi System Pressure 310 vs 309 CR ★ Deepest dig in Cat mini range: 205.2″ ( 22.4″ vs 309 CR) ★ Highest bucket force: 17,459 lbf ( 25% vs 309 CR) ★ Greatest max reach: 303″ ( 2.3″ vs 309 CR) Stick digging force: 11,060 lbf (vs 9,500 lbf) Extra counterweight option: 1,103 lb (new) Longer stick: 98.4″ standard (vs 71.8″ std on 309 CR) Hydraulic system: 37 gal (vs 29 gal) No high flow circuit (309 CR exclusive feature) Key Benefits & Features ★ Range-Topping Dig Depth — 205.2″ At 205.2″ (17 ft 1″), the Cat 310 achieves the deepest excavation depth of any Cat next generation compact mini. Enables deep utility trenching, sewer work, drainage infrastructure and foundation projects that smaller machines simply cannot reach. ★ Highest Bucket Force — 17,459 lbf 17,459 lbf bucket digging force — the most powerful bucket breakout in the Cat mini excavator lineup. Combined with 11,060 lbf stick digging force, the 310 breaks through compacted clay, hardpan and light rock conditions with authority. All Day Comfort — Cab Standard Sealed, pressurised cab with improved air conditioning, adjustable wrist rests and suspension seat standard on every 310. No canopy option on the top-of-range model. Dual Counterweight Options Standard counterweight ( 551 lb) and extra counterweight ( 1,103 lb) options give operators the ability to configure stability for heavy lifting applications — unique to the 310 in the Cat compact mini range. 303″ Maximum Reach Over 25 feet of reach from the long stick — the greatest reach envelope of any Cat next generation compact mini excavator — for wide-span drainage, embankment work and material placement across large areas. 62 GPM High-Capacity Hydraulics 62 gpm load-sensing pump flow with dual auxiliary circuits (35 gpm primary 9 gpm secondary) at 4,134 psi — delivering full attachment performance for hammers, tilting buckets, thumbs and other demanding tools. Customisable Operator Settings Programmable performance modes tune machine response across all functions — delivering up to 20% more performance versus previous generation Cat mini models. Lower Owning & Operating Costs Improved fuel efficiency, extended service intervals, load-sensing variable displacement hydraulics and ground-level side-door maintenance access reduce total ownership costs by up to 10%.
