Service: Hydraulically actuated dual line, self adjusting, oil
immersed, multi-disc type on the rear axle, well protected from
dirt, water etc. requiring no maintenance.Parking: Hand operated,
disc brake on rear axle input disc.Brake pedal: Two independently
operable foot pedals enable machine to manoeuvre in tight spaces.
Pedals are linked
together for normal use.Option for 4WD: Option exists on the
machine to automatically switch from 2WD to 4WD for effective
transmission braking.
BRAKES
• JCB vari-matic hydraulics • Main relief valve: 3300psi
(228bar) • Unloader valve: 3000psi (207bar) • Pump type: 2 section
displacement gear • Pump capacity: 110 lpm • Filtration through
suction strainer and return line JCB Filtermatic filter • During
excavation the circuit automatically varies hydraulic power to
match digging conditions for extra performance, control and power •
Careful routing of hydraulic hoses and pipework guards against site
damage and allows easy servicing
HYDRAULIC SYSTEM
front wheel full power hydrostatic system utilising the main
hydraulic pump via a steering priority valve. In the event of
engine failure, emergency steering is maintained (all models).

in all conditions. It consists of a 4-speed, full synchromesh
gearbox with integral torque convertor and electrically operated
reversing power shuttle.• Easy-to-use, column mounted electric
reversing shuttle which can change machine direction while allowing
operator to keep hands on the steering wheel leading to fast cycle
times.• The pedal layout and conventional 4-pattern gear lever with
transmission disconnect switch adds to the overall ease of
operation. On-the-move gear changes are possible.• Torque
convertor stall ratio is 2.52:1 (4WD)
