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.
