JCB is upgrading its mid-range wheel loader range, introducing the proven DNA from its 457 wheel loader to the 427 and 437 models, along with the smaller 411 and 417 loaders.

JCB’s new 411 and 417 wheel loaders feature the company’s EcoMAX Tier 4 Final/Stage IV compliant diesel engines, delivering 108 hp (81kW) in the 411 and 125 hp (108kW) in the 417. The larger 427 and 437 loaders operate with a Tier 4 Final/Stage IV Cummins diesel engine, offering 179 hp (133kW) and 183 hp (136kW) respectively.

Both of these engines meet the latest emissions standards without the use of a costly diesel particulate filter (DPF), reducing operating costs and complexity for the customer. All Tier 4 Final wheel loaders now feature a single-piece engine hood that can be electrically or manually raised to provide improved service access to the engine and cooling pack. The machines drive through automatic powershift transmissions for maximum productivity and efficiency.

All four machines feature fine mesh front grills to trap larger particles before the air enters a cyclonic pre-filter. The engine-cooling fan provides a cyclonic scavenge system to remove dust particles from the pre-cleaner, rather than using hotter exhaust gases to deliver the cyclonic action. Wide core cooling packs reduce dust accumulation, cutting the downtime required to blow out radiator cores. The single-piece hood also helps to provide a seal around the engine bay, cutting dust and dirt ingress. A reversible cooling fan is available as an option.

Operator Comfort

All four of the new wheel loaders will use the JCB CommandPlus cab, first seen last year on the larger 457. This totally new ROPS structure has A pillars that have been moved out to the same width as the rear of the cab, providing a larger interior with a panoramic front windshield. The machines feature JCB’s Command Driving Position with revised pedals, an adjustable steering column and seat-mounted hydraulic controls.

Switches and auxiliary controls have been repositioned on the right-hand A pillar, providing the operator with a simplified interior and easy access to all machine controls. The loaders have full-color LCD screens that incorporate access to the loader’s operating menus and act as a monitor for a rear view camera.

JCB’s CommandPlus Control system allows the operator to adjust auxiliary flow rates on the main screen. It is also possible to use the monitor to adjust SRS boom suspension engagement speeds where fitted and the timing of cooling fan reversal to clean out the cooling pack cores. The screen also offers an operator help system that lists switch functions if required.

The cab benefits from increased internal space, as the heating, ventilation and air conditioning system has been repositioned outside the main cab structure. This provides additional storage for the operator, both behind the seat and in pockets in the front and side consoles. The new cab, in combination with on-demand cooling fans and the Tier 4 Final engines contribute to a cut in noise and vibration, reducing operator fatigue and boosting productivity.

Operators benefit from a range of seat and control options, with electro-hydraulic proportional auxiliary controls now fitted as standard. An electric parking brake is standard on the 427 and 437 and available as an option on the smaller models. The exhaust silencers, and air pre-cleaners are all situated below the hood to provide maximum visibility for the operator.
