JCB has unveiled the next generation of backhoe loader, which will be on the ECI JCB stand at the National Ploughing Championships.
On the surface, it's a re-styled counterweight, with new vertical grille pressings and sharper lines on the excavator and loader profiles contributing to the new overall look. The cab is styled on the JCB Fastrac cab.
Under the skin, though, is where the new JCB makes the biggest impression, according to the firm. JCB claims it is the most efficient JCB backhoe loader ever, offering customers average fuel savings ranging from 6-16pc at typical daily work rates.
The savings are largely achieved through the introduction of a new EcoDig system, incorporating three hydraulic pumps.
This system uses three hydraulic pumps to provide the same hydraulic output -- but at lower engine speeds, which is saving fuel, says JCB.
The hydraulic system has two working modes -- eco-mode and low-flow, the former for productivity and the latter for control. Another benefit of the three-pump design, according to the manufacturers, is faster performance of the extra-dig extending dipper arm.
The new hydraulic system and lower engine speeds also contribute to a cut in exhaust emissions and a reduction in overall machine noise levels, both inside and outside the cab.
