JCB 90Z-1 Mini Excavators

BOOSTING EFFICIENCY

Fuel combustion in the 90Z mini excavators’ JCB Diesel by Kohler engine is so clean that the unit doesn’t require a diesel particulate filter (DPF). This reduces servicing, increases uptime and improves fuel efficiency.

Engine revs automatically drop to under 950 rpm when the operator’s armrest is raised. This combined with the Auto Idle feature therefore boosts economy and reduces noise; it can be set to activate after the controls have been unused for a set period.

Load-sensing hydraulics only consume power on demand so these JCB excavators will conserve your fuel for when it’s needed most.

There are two separate dig modes (efficiency-boosting ECO or productivity-enhancing Heavy) on the 90Z and 100C mini diggers, allowing you to tweak your performance for any job.

JCB’s patented near zero pressure return line circuit improves fuel efficiency by permitting the hydraulic pump to start working at a lower pressure.

By perfectly matching our boom and dipper, we’ve created optimal dig end geometry on these JCB machines, helping you to work and load in confined areas with ease.

COMFORTABLE FAVOURITES

We’ve boosted overall space in our 9-tonne excavator cabs. This means there’s plenty of storage, a phone tray, stowage nets and a cup holder. A large door provides easy safe cab access.

A 3-speed heater and window de-mister on your 90Z mini excavator with 9-adjustable air vents ensure a comfortable and productive working environment.

Our standard-fit fully adjustable suspension seat offers great comfort; the heated air suspension option boasts independent adjustable positions for maximum ergonomics. An informative colour LCD display is at the centre of our intuitive switch layout, and you can spec a reversing camera.

The hydraulic valve block has been isolated from the chassis by rubber mounts on these midi excavators, thus reducing in-cab noise and vibration. The valve block is nevertheless easy to access under the side-opening bonnet.

A standard-fit ergonomic electro-hydraulic dozer control ensures smooth and precise grading, while short pitched tracks engage every tooth on the sprocket, helping to reduce vibration and noise whilst maintaining a very smooth ride on the JCB 90Z.

ON THE SAFE SIDE

Front screen guards can be specified, along with boom and cab worklight guards. Optional boom, dozer and dipper hose burst check valves (HBCVs) make lifting operations even safer.

Safety lever lock isolates hydraulic functions to prevent unintended movements on these JCB diggers. So that your hydraulics are only operated in a safe lockable position, JCB’s 2GO system requires the operator to acknowledge they are ready to work.

There’s a clear view of the front right track on the JCB 90Z mini excavator, courtesy of a 70/30 front screen split. This makes trench digging and manoeuvring safer.

To reduce impact risk in tight workspaces, choose a ZTS excavator. Whichever machine you choose, fold back the door and you’ll see that it fits snugly within the counterweight length. This keeps it out of harm’s way while you’re working.

Stability on these JCB diggers is best-in-class. Hardly surprising when you consider that both are blessed with a large track frame width and a low centre of gravity.

Bodywork is made using 100% high strength pressed steel so it’s strong, durable and easy to repair. Flat glass windows are used throughout the 90Z excavator because they’re cheaper to replace in the event of on-site damage.

THE BEST SERVICE

Greasing intervals at the dozer and dig ends are a best-in-class 500 hours on these excavators, which saves you time and money. This is made possible because we use graphite impregnated bronze bushes.

For reduced fuel spillage and increased safety, fit your JCB 90Z with the optional refuelling pump with its auto stop function.

Key components like the rotary joint, swing cylinder, removable side skirts and in-fill panel are all easily accessed via the tilting cab. Tapered dozer lift points behind the blade edge makes it relatively easy to lift your digger for transporting.

Excellent SAE service rating on the market equates to greater uptime for the JCB 90Z mini excavators. Our machines are more serviceable courtesy of features like a gas-strutted 30-degree tilting cab that’s operable without special tools.

There are colour-coded hydraulic hoses to make identification simple on these JCB excavators. Hoses from the dozer all terminate at the bulkhead, which means that replacing them is easy.

Straightforward cleaning inside and out is assured on a 90Z mini excavator; the sealed idler tension unit and open frame undercarriage design with sloping track legs prevent material build-up, while the two-piece floor mat is easily removable.

THE STRONGEST CONTENDER

A simplified H-frame construction and finite element analysis have helped us to create the ultimate heavy-duty mini excavator structure. The JCB 90Z therefore combines durability with confidence-inspiring stability.

The fully robot-welded high tensile steel boom and dipper is strengthened with internal baffle plates to offer a long and trouble-free service life. For added structural strength, our clean and elegant dipper design is constructed from just four plates.

With a heavy-duty boom cylinder guard, and the option of dipper and crowd ram guards, the JCB 90Z mini excavators enjoy maximum excavator arm protection, even during the toughest jobs.

Excavator hoses are safely routed through our heavy-duty kingpost, which is made to last using durable re-bushable pivots. By using the very latest O-ring face seals (ORFS) throughout the hydraulic system, we’ve reduced potential leaks too.

Premium componentry comes as standard on the 90Z mini excavators. The spec list includes JCB Diesel by Kohler engines, Nachi and Bosch-Rexroth hydraulics, and Bridgestone tracks.

To help these JCB minis perform anywhere, they’re equipped with high quality 450mm rubber tracks with interlocking links. Optional 450mm/600mm steel tracks are pre-drilled for rubber pads. There’s also the choice of dedicated Road Liner Pads (Bridgestone GeoGrip).
