- Do daily maintenance at ground level. - Up to 20 percent less maintenance cost than the 320D2 GC due to enhanced filters and extended and synchronized service intervals (savings calculated over 12,000 machine hours). - The air intake filter with precleaner has double the dust holding capacity of the previous air intake filter. Final drive and swing drive oil is double the initial service life – from 250 to 500 hours. - Fuel filters are synchronized to be changed at 1,000 hours – double the interval from the previous filters. - The hydraulic oil filter provides improved filtration performance, anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3,000-hour replacement interval – 50 percent longer than previous filter designs. - Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to help increase undercarriage life. - Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components. - Advansys™ bucket tips increase penetration and improve cycle times. Tip changes can be done quickly with a simple lug wrench instead of a hammer or special tool, improving safety and uptime. - S·O·SSM oil sampling ports are on ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.

- The excavator uses up to 15 percent less fuel than the 320D2 GC in similar applications. - Match the excavator to the job with a choice of two modes: Power and Smart. Power mode provides full-time maximum output. Smart mode automatically matches engine and hydraulic power to digging conditions to help conserve fuel without impacting production. - Product Link™ comes standard so you can remotely monitor fuel consumption as well as machine health, location, and hours on demand through VisionLink®. - Save fuel with Automatic Engine Control (AEC). It reduces engine speed when the machine is not under load to minimize fuel consumption.

- Access daily maintenance points from ground level with the exception of the engine oil level – no need to climb on top of the excavator to check filters or grease linkage. - An optional ISO certified Rollover Protective Structure (ROPS) cab is offered in some regions to help protect the operator in the event of a rollover. - Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab posts and larger windows. - An optional rearview camera enhances visibility. - Anti-skid plating on the service platform helps prevent slipping. - The handrails meet ISO 2867:2011 requirements for added safety. - Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the push button starting feature. - Enhance jobsite safety. Add a swing alarm to alert people when you're rotating from trench to stockpile and back again.
