The JCB 427 wheel loader's main joint has a reinforced box section, reinforced central pin, oversized bushing and two tapered roller bearings on the lower box joints. This arrangement easily withstands vertical and horizontal loads.
Finite element analysis and extensive hardware and strength testing ensure excellent structural strength and durability. Cold chamber tests guarantee starting efficiency up to -20C.JCB's precision machining techniques ensure high tolerances and accurate pin and bushing placement. State-of-the-art manufacturing processes such as robotic machining, precision paint technology and modern assembly techniques are used to achieve the highest levels of quality.A solid rear counterweight protects the rear of your JCB 427 from damage, including the rear lights and cooling block. The hoses passing through the main joint are carefully guided and fastened, well away from pinch points.
The new front chassis is more durable than before. To ensure exceptional longevity, it has been reinforced with additional ribs and gussets. Additional protection is provided by fitted impact-resistant wing edges and profiles.

This wheeled loader has built-in steel fluid reservoirs, providing exceptional protection against leaks, a much better solution than the plastic reservoirs favoured by some competitors.

The ROPS / FOPS structure on the 427 wheeled loaders has been redesigned. The width of the “A” pillars is the same as the rear of the machine, enlarging the cab interior and the panoramic windscreen. The auxiliary circuit switches and controls are now on the right A-pillar.
There are two colour LCD screens for navigating the working menus. One of them can display the image from the rear camera. The simple, purpose-designed interface is easy and intuitive to use with an optional control knob.
Standard equipment on the JCB 427 AGRI wheeled loader includes heated exterior mirrors that can be electronically adjusted from the cab. Convex mirrors are also available to widen the field of vision.The all-new ventilation system has nine de-fogging vents and six ventilation vents to ensure visibility and operator comfort in all situations. In addition, the system operates quietly.All controls are mounted in the seat, moving with the suspended seat. You can choose the control system best suited to your operators: a single-lever joystick or a multi-lever version, both with electro-hydraulic functions for exceptional precision.

Following extensive ergonomic studies of the operator environment, we developed the ‘Command Driving Position’ system, which ensures optimal positioning of controls, taking into account the drivers' diverse physiques.

On the JCB 427 AGRI machines, the Auto Idle function brings the engine back to 700rpm after 30 seconds of inactivity. Another function, Eco Mode, limits engine speed to 1800 rpm for fuel economy. In any case, productivity remains sensational.
The hydraulic cooling fan automatically responds to the ambient temperature and adjusts its speed to optimise cooling and reduce fuel consumption. An added benefit is lower noise levels in the workplace.Locking the torque converter of our six-speed transmission on this wheeled loader means you can enjoy 100% efficiency in every gear. Shorter gear ratios mean lower engine revolutions in each gear.Braking at wheel speed means that the brakes rotate at the same speed as the wheels to reduce heating, friction resistance and increase fuel economy. At no load, the control valves in the valve block lower the arms using gravity, thus reducing fuel consumption.

JCB's innovative variable displacement pumps power a load-sensitive valve block that draws power only when required, providing precise, efficient control of the loader.

The JCB Smoothride bucket cushioning system reduces impact loads, reduces material spillage and lowers structural stresses, and improves operator comfort. The speed that causes the system to engage is set from the cab using the state-of-the-art Command Plus control.

Access to the engine on the new JCB 427 AGRI wheel loader is easy thanks to the large, one-piece, automatically opening bonnet. Similarly, it is easy to reach the fuel and DEF tanks from the rear of the machine through the lockable grille.
The heating and ventilation filters are conveniently located behind the external access panel. From inside the cab, you can check the windscreen washer fluid level, engine oil level and coolant level; all other routine checks and lubrication points - from ground level.The cyclonic blowdown engine filter provides four times the cleaning capacity of a standard air filter. It is a longer-lasting system with fewer components and higher efficiency, providing better engine protection.Most Tier 4 Final / Stage IV engines use diesel particulate filters (DPFs), costly and time-consuming to replace. The Cmmins engine has no DPF, reducing servicing and operating costs.

Thanks to the use of excellent components in the JCB 427 AGRI wheel loader ( Cummins engine, ZF gearbox and axles, Rexroth pumps and Parker valve blocks), exceptional machine life has become standard.
