Mini Excavators 310 – Tier 4 / Stage V
Original price was: $173,874.00.$109,540.99Current price is: $109,540.99.
★ 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%.
