JCB emissions compliant engines to launch in wheeled loaders
JCB's 427 and 437 loaders use Cummins power
JCB will launch 427 and 437 wheeled loaders at Bauma, powered by Stage IIIB/Tier 4 Interim Cummins engines.
First seen in prototype form at last year’s Intermat show, the two loaders are powered by the Cummins QSB6.7 engine, which offers a 9.4% increase in torque over the previous model. This drives through a lock-up converter and customers can choose a standard four-speed or optional five-speed transmission, which delivers a 16% drop in fuel consumption. In-cab noise levels have been reduced to just 68dB(A) and the machines feature new styling on the cab, rear chassis, bodywork and counterweight.
An intelligent clutch cut-off system is standard with both transmissions, making the machines ideal for truck loading and tight site manoeuvring. The system automatically adjusts the clutch cut-off point depending on transmission output torque and brake pressure, reducing wear in the transmission and the axles. The two machines are available in parallel-lift HT specification, with a powerful Z-bar linkage or with High Lift and Super High Lift ZX arms.
