JCB introduces Tier 4 Final engines and a high degree of machine automation for its 2015 backhoe-loader model line-up. Through development of its own range of Ecomax diesel engines, the company has achieved the Tier 4 Final emissions standard without the need for a diesel particulate filter (DPF), reducing cost and complexity for the customer.
Both the rental-market 3CX, now built in JCB’s Savannah plant, and the 3CX-14 model are powered by a 74-hp version of the Ecomax diesel engine. With no change required from the Tier 4 Interim model, this engine has no DPF or exhaust aftertreatment. The 3CX-14 will also be offered for the first time with an optional powershift transmission and Advanced Easy Control (AEC) servo levers. An air suspended operator’s seat is also available with standard AEC.
The 3CX Super is offered with a Tier 4 Final Ecomax engine rated at 91 hp or an optional 109-hp engine, while the 4CX Super comes standard with the 109-hp engine. Both engines use selective catalytic reduction (SCR), with a diesel exhaust fluid (DEF) additive to meet Tier 4 Final emissions. DEF usage is less than 3% compared to the diesel, so the DEF tank will only have to be topped off once for up to 10 tanks of fuel.
The 3CX Super model includes standard front impact protection bumper bars, and both the 3CX Super and 4CX Super models come with a standard 11,000-lb. lifting eye on the backhoe.
Automation features on the 3CX Super and 4CX Super backhoes include:
- Auto Smoothride System (SRS): This set and forget system requires no further operator input once activated. Activation and deactivation of the loader arm suspension system is automatically controlled at a preset speed, providing improved ride comfort and load retention.
- Auto Boomlock: Standard on servo models, this feature automatically locks the backhoe in any slew position without the need for any cable release mechanism. The boom is automatically unlocked with servo activation.
- Auto Up Stabilizers: Also standard on servo models, this feature provides one-touch levers to raise the stabilizer legs. Engine rpm automatically rises during activation to further cycle times up or down.
- Additional systems include auto return to idle, auto drive, auto throttle, automatic daily checks and automatic engine and cab pre-heat.
