JCB launches newest ag-spec loader

The loader is its most powerful and heaviest machine to date, topping the scales at 20 tonnes and offering a payload capacity of over 6 tonnes. The machine is likely to appeal to contractors who need to shift large volumes of grass or maize silage in the race to keep up with high output self-propelled forage harvesters.

The development, a derivative of the industrial-focused 457 machine, has seen the inclusion of a new rear chassis and counterweight – alongside changes to the transmission, axles and wheels.
Power is provided by a 6.7 litre, six-cylinder Cummins engine that delivers a peak output of 282hp power and 1,200Nm torque. It can work in economy mode, where output is restricted to 224hp, and also features an automated engine shut-down function that kicks in after an extended idle period.

With both functions aimed at fuel savings, JCB reports that during clamp work, consumption is typically around 14 litres/hour – similar to the existing 435S.

The transmission takes the form of a new powershift unit supplied by ZF. It comes with manual/auto modes, 6 forward and 3 reverse speeds. The loader also features a torque converter lock-up function to achieve a mechanical drive for increased traction and pushing power.

Its heavy-duty, 20-stud axles are equipped with limited slip or auto locking differentials and shod on 710-75R32 Trelleborg or 800-65R32 Michelin MegaXbib tyres, both keeping overall width under 3 metres.

Standard ‘high torque’ loader arms offer a 4.3m lift height, although buyers can specify the high lift option that increases this to 4.8 metres. Optioning the machine to the Contractor Pro specification adds 360-degree LED lighting, cab carpet, a super deluxe half-leather seat, twin beacons and a stainless-steel exhaust stack.

JCB has also announced the arrival of a new 4.8m wide, 7.1 cubic-metre capacity folding buck rake, developed specifically for this machine.
