JCB JS220
The JS220 excavator is the first JCB excavator model over 20 tons to feature the company’s innovative and highly efficient Ecomax diesel engine. The 4.8-liter engine delivers 172 hp and is equipped with 29,000 psi fuel injection, a variable geometry turbo charger and full electronic engine control for a 10 percent cut in fuel consumption and improved engine responsiveness. As with all JCB Ecomax engines, the clean burn technology eliminates the need for a costly diesel particulate filter (DPF) or other expensive after-treatments.
Because there’s no need for a DPF, JCB has been able to retain reduced engine cover lines on the JS220 for improved visibility. A new cooling fan cuts fuel use and reduces noise. A revised boom and dipper arm with deeper steel sections and castings in key pivot points enhances the JS220’s durability. As a result, the JS220 offers reduced ownership costs for the customer.
The JS220 features improved operator comfort with a standard 7-in. color monitor, enhanced JCB LiveLink functionality and JCB’s Tool Select attachment system. The monitor is easy to read in all light conditions and provides operators with customizable home screens. The LiveLink telematics system gives fleet managers and machine owners additional data to help them reduce fuel consumption and operating costs.

Volvo EC220D
The Volvo EC220D is part of the fuel efficient, environmentally friendly D-Series Volvo crawler excavators, providing operators with greater digging forces and faster cycle times. Powered by a Volvo D6H/Tier 4 Interim engine and ideally matched components, the EC220D delivers high power and excellent lifting capacity and stability.
Offering operators advanced control on the EC220D is the “smart” hydraulics system — enabling smooth and highly responsive combined operation and travel. The system automatically prioritizes oil flow to the boom, arm or slew function according to requirements, resulting in faster cycle times. An attachment management system can store up to 18 presets and enables hydraulic flow to adjust to meet the requirements of the attachment in use.
The ROPS-protected cab allows EC220D operators to sit in a roomy, low fatigue, climate-controlled environment, with clear visibility and easy-to-handle controls.
Service is made simple, with easy-to-reach maintenance points accessed via wide-opening compartment doors. A service mode is incorporated into the I-ECU color monitor to allow diagnostic checks to be conducted. Four separate service intervals — engine oil/filter, fuel filter/water separator, hydraulic oil and hydraulic oil filter are all displayed on the monitor.
CareTrack, Volvo’s telematics system, is standard on new Volvo excavators and provides owners with machine intelligence that helps reduce fuel costs, optimize performance and maximize uptime.

Yanmar ViO35-6
Introducing the most innovative, fuel-efficient excavator Yanmar has ever built. The advanced technology zero tail swing ViO35-6 features an electronically controlled Tier 4 engine and dramatically evolved hydraulic system. It also comes standard with ECO and Auto-Deceleration modes for even more operational efficiency. All of which means the new ViO35 can now deliver up to 20 percent less fuel consumption than previous models without sacrificing any of the power.
The new digital Smart Assist control system allows owners to monitor up to three months of operational history. Because this state-of-the art system centralizes control of machine operation information and maintenance support information, it’s never been easier to maintain a timely, efficient service process.
The standard hydraulic Quick Coupler makes changing buckets fast and easy. With the exception of fitting and removing the safety lock pin, the entire operation is performed electronically while the operator is seated in the comfort of the cab.
The innovative design puts virtually every major component — engine, hydraulic system, starter, generator and battery — right at your fingertips. Because routine filter and grease fitting checks are easier and quicker, you can perform them more often, extending the life of and improving the durability of the machine.

Cat 336E H
The new 336E H is the industry’s first hydraulic hybrid excavator. This unique machine uses recovered energy from the swing during the ditching process to use significantly less fuel than Caterpillar’s powerful 336D machine during similar applications.
The 336E H uses three building block technologies to deliver outstanding fuel savings and performance:
• The Cat Electronic Standardized Programmable (ESP) pump transitions between the hydraulic hybrid power sources, engine and accumulator to conserve fuel.
• The Cat Adaptive Control System (ACS) valve optimizes performance by managing restrictions and flows to control machine motion, which means operators have the power and precision they need and expect.
• The Cat Hydraulic Hybrid Swing System captures the excavator’s upper structure swing brake energy in accumulators and then reuses the energy during swing acceleration.
The 336E H features three power modes to help manage fuel consumption: high power, standard power and economy. Two additional fuel-saving features are on-demand engine power and engine idle shutdown. On-demand engine power keeps speed low during light loading and idling, then adjusts when it senses a heavier load. Engine idle shutdown automatically shuts off the engine when idling for more than a specified amount of time.
The 336E H runs on ultra-low-sulfur diesel fuel, but the C9.3 ACERT is equipped to run on biodiesel fuel up to B20.
