Powerful performance, increased productivity
Find a dealer to learn moreGet power and efficiency in a big package with a hybrid excavator designed to reduce fuel consumption while driving performance. When swinging, all available hydraulic power is sent to the boom, arm and bucket for improved cycle time and increased production.
All hybrid components are covered by a 7-year/15,000 hour fully transferable warranty.
15% increase in productivity *
* Compared to the non-hybrid excavator designSuperb swing power and speed with an ultra-capacitor that captures energy then charges and discharges rapidly to power the electric swing motor.
Control costs and reduce your carbon footprint with a hybrid energy conservation system that combines with Tier 4 Final technology for up to 20% fuel savings compared to the non-hybrid excavator design.
Complete jobs quicker
Get fast cycle times and boost productivity with a powerful electric swing motor and a closed-center load sensing system (CLSS). The CLSS delivers hydraulic power to the excavator for an immediate high performance, smooth and precise operation.
Track valuable machine data with the KomtraxTM remote equipment monitoring and management system, standard and with no subscription fees. KomtraxTM also provides advanced machine troubleshooting capabilities by continuously monitoring machine health.
Improved stability
The HB365LC-3 excavator features a 6% increase in operating weight* designed to help its stability so operators can dig, lift, and handle heavy materials confidently and effectively, especially when working on uneven or challenging terrain.
