The combination of a JCB DIESELMAX engine with ZF axles and transmission delivers exceptional traction and digging/loading ability on the JCB 422ZX wheel loader.
Z-type loader arm geometry generates maximum breakout forces and increased reach during lorry loading.
We’ve been designing and developing JCB DIESELMAX engines at our dedicated state-of-the-art facility since 2005. With tens of thousands of units in service around the world, we’re building a formidable reputation for performance and reliability.
A ZF fully automatic 4-speed 4WD powershift transmission automatically senses the perfect gear for your JCB 422ZX loading shovel, whatever the application. For increased traction, there’s also a manual gear kickdown function on the loader lever.
The JCB 422ZX has ZF axles with limited slip differentials fitted as standard to provide maximum traction in any ground conditions.
Our simple and reliable hydraulic circuit comprises twin gear pumps and an unloader valve block. The versatile optional three spool valve block means you can use attachments like grabs and sweepers. A standard float function allows simplified grading and levelling.

We’ve tested the JCB 422ZX wheel loader in climates ranging from -20°C to 50°C. Its DIESELMAX engine is tried and trusted, with excellent filtration and robust fuelling to handle varying fuel quality.
Advanced manufacturing and assembly processes mean we produce only the very highest precision quality components for our loading shovels. IP67 electrics keep out water and dust.
The JCB 422ZX wheel loader is equipped with tried and proven ZF axles.
Because industry is tough, we stress test this loading shovel across 1.2 million cycles to emulate the toughest digging and dump situations. That means all structures can perform even the most arduous duties over thousands of hours.
Our durable centre joint features twin taper roller bearings as well as a heavy duty pin and bush assembly.
To protect steer rams and hoses from damage, they’re positioned high up above this wheel loader’s robust centre joint.

The JCB 422ZX wheel loader’s cab is fully compliant with ROPS/FOPS standards.
We’ve fitted air conditioning and a heater, as well as sliding windows on both sides of the cab so that your loading shovel operators stay as comfortable, alert and, therefore, productive as possible.
Our fuel panel is mounted in the JCB 422ZX’s cab for quick and easy access.
Servo loader controls make operating this wheel loader extremely precise, and provide smooth, low effort, fatigue-free operation.
All-round visibility on the JCB 422ZX is excellent; a modern rear mounted cab design, large glass areas and narrow pillars give a clear view, particularly to the front shovel.
Large inclined steps and ergonomic grab handles make cab access safe and easy. The JCB 422ZX loading shovel also has a conveniently placed toolbox for safe and secure storage
