3.5-ton model

JCB offers the 35Z-1 3.5-ton zero tail-swing compact excavator to its Next Generation equipment line-up.


The 35Z-1 model features an engine designed for global marketsand a  new hydraulic system, larger ROPS cab/canopy with new instrumentation, improved dig-end geometry with 1.73-inch bucket pins and 500-hour greasing intervals. The easy to clean H-frame undercarriage design with auto kick-down motors andreprofiled dozer blade deliver increased productivity

JCB 35Z-1 zero tail-swing excavator
The new 35Z-1 zero tail swing model is a replacement for the previous generation 8035ZTS and is ideal for working in confined areas, providing greater protection as the counterweight rotates within the width of the machine.

The new 35Z-1 zero tail swing model is a replacement for the previous generation 8035ZTS. The zero tail-swing model is ideal for working in confined areas, providing greater protection as the counterweight rotates within the width of the machine.

It is powered by a three-cylinder Perkins engine, delivering 24.7 horsepower. This engine uses mechanical fuel injection and has doesn’t require a diesel particulate filter (DPF) or any form of exhaust after-treatment. The engine is EPA approved for the North American market and can be used in global Tier 3 regions.

A programmable 2- to 30-second auto-idle function reduces engine speed to 1,400 rpm when the levers have not been used for a pre-set time. When the left-hand control pod is lifted, it isolates the machine’s hydraulics and the engine speed falls to 1,100 rpm, reducing fuel consumption and noise levels.

A large engine canopy provides easy access to daily checks, with a scalloped counterweight providing easy changing of the engine oil filter. A hinged air conditioning radiator (where fitted) swings out to provide access to the main radiator for cleaning.

The machine uses the latest Bosch-Rexroth variable displacement, load-sensing, electro-proportional hydraulic pump. This new technology eliminates stalling, making it possible to utilize all of the engine’s output. A closed-center valve block improves fluid flow, for smoother, more precisely controlled operation, particularly when multi-functioning. The valve block is easy to access for any service needs.

The hydraulic system has all O-ring face seals for maximum sealing; all hydraulic hoses are color-coded for easy identification. High-flow, electro-proportional, double-acting auxiliary hydraulics are now standard on the machine, delivering 18.5 gpm of flow. The auxiliary flow is controlled using a proportional thumb roller on the right-hand joystick.

A single- to double-acting changeover is now electronically controlled by a switch in the cab, rather than the manual changeover tap on the previous generation machine. Doubleacting low-flow auxiliary hydraulics can also be specified, delivering 8 gpm of flow. This circuit is controlled through a thumb roller on the left-hand joystick. Selectable high and low flow auxiliary modes, from 5 to 100 percent of the available flow, provide compatibility with all brands of attachments.

The new ROPS/TOPS cab and canopy structure features flat glazing throughout to minimize replacement cost. An optional FOPS Level 1 guard is offered for further protection. The front screen has a 70/30 split for maximum visibility to the working area. The lower glass section can be removed and stored inside the rear left-hand window. Slim cab pillars provide excellent visibility all around the machine.

Available as a canopy, a cab with heater, or a cab with air conditioning, the spacious working area provides increased legroom for the operator. There are no auxiliary or boom offset pedals on the floorfor greater comfort in the cab. Bolt-on grab handles and a large door aperture make it easy to access the high-backed suspension seat. An electro-proportional dozer control is standard and the removable floor mat is easy to clean, with no logos or steps.

The membrane switch layout to the right of the operator is easy to read and a new 4-inch display screen that provides all operating information including an automatic health check with the first key-on at the start of the day. A rotary work mode controller controls the engine and hydraulic output, while two toggle switches allow the operator to personalize the information available on the main screen. Where hose burst valves are supplied, a Load Moment Indicator (LMI) can be activated in the screen, providing an indication of safe working loads when lifting.

The cab includes a Bluetooth radio and there is a 12-volt socket and two USB ports for charging of mobile phones and other electrical devices. Both the cab and canopy have LED work lights as standard, with follow-me-home functionality.

As with all JCB compact excavators, the 35Z-1 and is equipped with JCB’s 2Go safety system, that requires the operator to press a secondary switch to activate the hydraulic controls. The machines are provided with an immobilizer to prevent theft and JCB LiveLink is standard, providing a telematic link to the excavator to ensure that it remains well-maintained and delivering maximum productivity.

Robust construction

The machine uses a new H-frame undercarriage design for increased rigidity. This open-center design allows dirt and debris to fall from the carriage, reducing material build-up. The track legs have chamfered edges, also making it easier to keep clean. A smooth front idler, four bottom rollers and a single top roller ensure a smooth ride and the Nachi track motors have an auto-kickdown function.

There are 12 dedicated tie-down points on the machine, including on the dozer blade, eliminating the need to tie straps or chains across the tracks.

The dozer blade design has been improved, with a revised curvature for improved roll performance. Pivot pins feature pin-end greasing, making it easier to service and all plated surfaces are angled to minimize dirt and debris retention. Dozer ram hoses now pass through bulkhead connectors, mounted on the outside of the undercarriage, making it easier to replace them in the event of accidental damage. Optional dozer float and a four-way dozer are now offered.

Dig-end geometry has been revised to improve lifting and loading performance. A single 8-foot main boom is used with a standard counterweight. Graphite impregnated bronze bushes have extended greasing intervals on the digging and dozing equipment to 500 hours and the heavy-duty bushed kingpost now comes with re-bushable pivots, to boost service life.

The dipper arms are thumb-ready as standard. The revised bucket pin geometry now matches other manufacturers, making it easier for customers to utilize attachments across mixed fleets. A conversion hitch will enable the machine to work with the previous generation buckets. There is also a new JCB factory-fit hydraulic quick-hitch option, featuring two locking mechanisms and an LED boom light warning indicator. This CE-marked hitch has been designed to meet all current and expected future legislation.
