427 HT JCB 427 HT Specifications & Technical Data (2013—2017)

Low Maintenance Long Intervals

A wheeled loading shovel needs to spend the maximum amount of time hard at work. We’ve designed the 427 and 437 to do just that, with long service intervals and quality components.

Maintenance benefits

JCB LiveLink makes it easy to manage machine maintenance. Accurate hours monitoring and service alerts improve maintenance planning, and real-time location data helps you manage your fleet. You'll also have access to critical machine alerts and maintenance history records.

Security benefits

Keep your machine operating safely with JCB LiveLink. Real-time geofencing alerts tell you when machines move out of predetermined operating zones, and real-time curfew alerts inform you if machines are being used when they're not supposed to be. Real time location information helps you store your machines in the safest places.

Irrespective of what you opt for, our Maintenance teams around the world charge competitive labour rates, and offer non-obligation quotations as well as fast, efficient insurance repair work.

Drivetrain productivity

The 427 and 437’s optional 5-speed transmission with torque convertor lock-up provides closer ratios for better acceleration, hill climbing and roading performance. The lock-up element eliminates losses from the torque converter for faster cycle times and improved efficiency. The innovative electronic management can perform progressive clutch cut-off for efficient, productive loader control. This feature controls tractive effort via the transmission, diverting maximum power to the loader hydraulics and reducing service brake wear and fuel consumption. With a range of axle options you can tailor a 427/437 to any application. Open differentials are ideal for hard standing ground conditions. Limited slip differential is perfect for soft, muddy terrain with reduced traction. Open differentials with an automatic locking front axle differential provide excellent traction in varied ground conditions.

An efficient engine

Automatic idle returns the engine to 700rpm after 30 seconds of inactivity. The 427/437’s Eco mode limits engine speed to 1800rpm for reduced fuel consumption. Productivity remains formidable.

An efficient driveline

Our torque lock-up 5 speed transmission option gives 100% efficiency in gears 2 to 5 for improved fuel consumption. Closer gear ratios provide lower engine speed in each gear. Wheel speed braking means the brakes rotate at the same speed as the wheels for heat and drag reduction, as well as improved fuel economy. Available on the 427 Agri model is the optional 6-speed gearbox giving optimum gear matching to the application, also features LUC from 2 to 6.

An efficient hydraulic system

A hydraulic cooling fan automatically reacts to ambient temperature and adjusts the fan speed to optimise cooling and reduce fuel consumption. This also lowers noise. Unloaded spool valves in the valve block mean that arms lower under gravitational, not hydraulic force, reducing fuel consumption.

Loading productivity

JCB’s optional quickhitch makes attachment changing quick and efficient. The quickhitch is designed to be compatible with aftermarket attachments too. Powerful twin variable displacement piston pump hydraulics can circulate a massive 264 l/min for fast cycles and excellent multi function capability.

Quality built in

By using top components in the 427 and 437 (Cummins engine, ZF transmissions and axles, Rexroth pumps and Parker valve blocks), we've built in long service life as standard. Full hydraulic dual circuit braking with multiple oil immersed disks gives the braking system a virtually maintenance-free lifespan. Check brake, steering and hydraulic system pressures easily on a 427 and 437 with group test ports.

Engine – 427/437

6-cylinder, charge air cooled, variable geometry turbocharged, electronically controlled high pressure common rail injection, cooled exhaust gas recirculation and diesel oxidation catalyst. A remote sump oil drain facility simplifies servicing.

Comfortably Superior

Keeping operators fresh and alert all day long results in increased safety and productivity. With that in mind, the 3m³ cab is roomy, easy to access, and quiet. It also has excellent visibility and intuitive to use ergonomic controls.

In control

A tilting and telescopic steering column provides easy adjustment for maximum comfort.A range of loader controls; multi-lever, joystick, or joystick with proportional auxiliary controls.A stylish, modern central dash display combines analogue dials and a colour LCD screen – this can display machine health details, service requirements, operating information and more.

Seat Options

The 427 and 437 have a range of seat options: mechanical or air suspension, vinyl or fabric bases, or even our Actimo XXL option. It’s heated with air suspension, lumbar support, armrests, backrest extension and a headrest, all with full adjustment.

Exterior comforts

3 or 4 spool hydraulics and a quickhitch enable many attachments to be used easily for extra versatility.The selectable loader arm detents mean operators can set loader arm height limitations, return to dig and float functions for improved safety and productivity.JCB Smoothride load suspension limits shock loadings and therefore reduces material spillage and structural stress, as well as increasing operator comfort.A 3-piece laminated front screen provides excellent visibility while interior mirrors, heated exterior mirrors, an optional reverse camera and a sloping rear bonnet give good rearward views.

A Quality Process

We know that a wheeled loading shovel is a key part of the on-site process. That’s why the JCB 427 and 437 are built on a foundation of quality and reliability. The processes we’ve used to design and manufacture them will safeguard your working process, hour after hour, day after day.

Well articulated

The articulation joint has a heavy-duty box section – much stronger than a single plate with a boss. Steering rams are positioned high up and well protected from possible impact and site damage. Hoses are neatly routed and clamped through the articulation joint, well away from any pinch points.

Loading productivity

You can choose your ideal loader arm on a 427/437, with z-bar linkage (ZX) for high breakout applications or high torque (HT) for parallel lift and multi-attachment use. Choose a HT high lift on the 427 or 437, or super high lift HT on the 437 and you can use the machine for higher loading height applications (hopper and lorry loading).

Loader – 427/437 HT

Widely spaced four ram geometry provides the combination of excellent visibility with high bucket torque characteristics throughout the working arc. The pin, bush and sealing design on all pivot points provide extended maintenance intervals.
