Numerous advances made to JCB wheel loaders

JCB’s 427 and 437 wheel loaders replace the 426 and 436 and are powered by the Cummins QSB 6.7 litre engine. “With the 427 and 437 wheeled loaders, JCB has taken our larger machines’ technology and applied it to mid-weight models, bringing new levels of productivity and performance to the loader market,” said Tim Burnhope, Chief Innovation and Growth Officer. “These loaders will deliver...more tons per gallon in performance.”

The highly efficient engine meets the Tier 4 Interim emissions legislation through the use of a diesel oxidation catalyst (DOC), but without any requirement for a diesel particulate filter (DPF) or any exhaust after treatment additives. The DOC has been designed to last the life of the engine.

The JCB 437 provides 173 hp (129 kW) – equivalent to the outgoing 436 model, while the JCB 427 offers 158 hp (118 kW) and a 9.4 percent increase in torque, taking it to 591 lbf-ft.

Smart engine efficiency features including low idle setting (700 rpm), power and economy modes, optional idle shutdown.

A lock-up torque converter on the optional five-speed transmission activates in gears two to five, reducing losses from the transmission and increasing productivity. This means customers will really notice the difference on hill climbing, roading, and load and carrying duties.

Both models deliver 100 percent traction with the new automatic differential locking axles.

An intelligent clutch cut-off system also comes as standard, for both the four-speed and five-speed transmissions, making it ideal for truck loading or tight corner maneuvers.

Also new on the 427 and 437 is the option of climate control, the first time this has been offered on this size of JCB wheeled loader. There is also an improvement in fuel consumption by up to 16 percent using the optional new five-speed transmission and lock up converter. For added comfort, cab noise levels have been reduced to 68 dBA.
