Engine
- The 722 is driven by a 5.9 litre engine producing 240 gross horsepower at 2400rpm, allowing top speeds of approx. 50kph (31.07mph).
- The engine itself features low noise levels, improved efficiency and boasts high performance ensuring low operating costs while complying fully with European and North American
off-highway emissions regulations.
- A Bosch in-line pump provides optimum low speed torque and reduced smoke by precisely matching fuel/air mixture across the operational speed.
- An additional Wastegate Turbocharger provides higher cylinder injection pressures, resulting in cleaner combustion.

Transmission
- JCBs ADT range feature a ZF Smooth-shift transmission that provides "best in industry" performance with smooth gear changes which help reduce operator fatigue.
- The transmission provides 6 speed forward and 3 reverse gears with a choice of automatic or manual operation interchangeable on route. Constant 6 wheel drive, with longitudinal lock
up available on both axle and transmission at the touch of a button.
- Super Max Trac limited slip differentials are fitted as standard for automatically engaging optimum traction system in even the softest conditions.
- To complement the power provided by the engine and transmission, the 722 boasts a cast centre articulation design with 360-degree oscillation, ensuring the cab always remains
vertical.

Cab
- The spacious operators cab is centre-mounted on the front frame of the machine so as to increase all round visibility and stability.
- The cab itself is Roll Over Protective Structure (ROPS) and Falling Object Protective Structure (FOPS) approved for operator safety.
- The cab features large windows for all-around 360 degrees visibility. Air suspension seat, seat belt, extra training seat, tilt steering and air conditioning are all fitted as
standard with a variety of options available to suit individual needs.
- The cab itself is isolated from the chassis minimising noise and vibration which in return reduces operator fatigue during long shifts.
- The cab is electro-coated passing through a total of 17 treatments before undergoing powder coating which gives a unique hard, resilient finish promoting long term reliability and
durability.

Controls
- All switches, including body tip lever, gear selection, direction indicators, windscreen wipers and heater controls are within easy reach of the operator and easy to use.
- The JCB Electronic Monitoring System (EMS), monitors all vital functions and communicates information easily to the operator. In the event of a system failure, EMS shuts the machine
down, protecting both the operator and the machine.
- EMS also has added safety benefits, allowing only first gear to be selected when the body of the machine is in the raised position.
- The 722 also features a suspension system which the EMS controls to ensure that the same ride height is maintained, laden or unladen. As well as the front suspension, the 722
incorporates rear bogie beam suspension on both the intermediate and rear axle.

Hydraulics and Bodywork
- The 722 uses a simple twin gear pump design providing an effective hydraulic system that is uncomplicated yet economical.
- The hydraulic tank is situated on the front-right of the machine, with the filler located on the top of the tank for easy access along with an inspection cover for easy strainer
renewal and cleaning.
- The rear chassis of the 722 is made from high tensile strength steel and has large box section reinforcements for rigidity and resistance to loading forces. Tip is achieved via dual
acting single-stage dump cylinders that are mounted on the outside of the body.
- The body of the 722 is low and wide, providing a low centre of gravity and gives a lower load over height and a wider target for excavator or loader operators. The improved 74
