JCB 427 – specifications
Series: Other models
Build year not documented · Data origin: Manufacturer information · sources
The JCB 427 stands in the upper part of JCB's wheel loader range. Built for quarries, recycling yards, port handling and large construction sites, it moves bulk material in quantities where smaller loaders would have to drive too often. The articulated frame lets it turn in tight space even with a large bucket, and the hydraulics are tuned for short cycles.
The number 427 gives the size class and is not a power figure. A feature of the series is the availability of several special versions, among them Agri for farms; the model described here without a suffix is the general version for construction and industry. Depending on the job, buckets, forks or snow blades are fitted. Engine output, lift capacity and tipping load are found in the data sheet of the individual machine, as the values differ with year of manufacture and emission stage.
JCB 419S – British wheel loader from JCB in Rocester with a 136 kW diesel engine, 10,403 kg operating weight, a 1.6 m³ bucket and a 6,970 kg full-turn tipping load
JCB (Joseph Cyril Bamford) is a British construction-equipment manufacturer based in Rocester, Staffordshire, founded in 1945 by Joseph Cyril Bamford, whose initials still form the company name today. The 419S recorded here is a wheel loader from the company's range, which alongside its well-known backhoe loaders also builds dedicated wheel loaders in various size classes.

The 419S produces a maximum of 136 kW from a diesel engine and has an operating weight of 10,403 kg. The bucket holds 1.6 m³, payload is 3,485 kg, and the full-turn tipping load is 6,970 kg.
At an operating weight of just over 10 tonnes, the 419S sits in the mid-size segment of wheel loaders, common in earthmoving, agriculture and material handling on storage and recycling yards. The full-turn tipping load, the tipping load with the articulation joint fully steered, is the decisive limit for safe work with a full bucket while cornering on articulated wheel loaders, and here it is markedly lower than the straight-ahead payload.
When buying one used, check the articulation joint and its bushings for play, since the gap between payload and tipping load shows how close to its stability limit the machine works while cornering. Before buying, it is also worth checking the bucket teeth and edge for wear, the boom and bucket hydraulic cylinders for leaks, and the diesel engine's service history.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
