Easy Shift JCB synchroshuttle transmission provides effortless gear shifting with column mounted rotating switch. It
consists of a 4-speed, fully synchromesh, smooth shift gear
box with integral torque convertor.
• Easy-to-use, column mounted electric reversing shuttle
switch can change machine direction while allowing operator to keep hands on the steering wheel, leading to fast
cycle time.
• JCB easy shift easy to use column mounted rotating knob
type gear shifting, adds to the overall ease of operation.
On-the-move gear changes are possbile
• Bigger and effortless foot throttle pedal.
• Torque converter stall ratio is 3.01:1.

AXLE
• Rear : Drive axle rigidly mounted, incorporates JCB
Max-Trac torque proportioning differential, driven by short
propshaft from gear box.
• Front : Steer axle, centrally pivoted, with oscillation angle
of 16º
.........................................................................................................................................................
Service : JCB ‘Q’ brakes, hydraulically actuated, dual line,
self adjusting (compensated), oil immersed, multi-disc type
on the rear axle, well protected from dirt, water etc. requiring no maintenance. Operated through independent
pedals linked together for normal use.

1 JCB ecoMAX 444 is one of the efficient & reliable
engines in construction industry. The combination of CRDI
technology with high pressure fuel line & swirl design in
combustion chamber reduces the complicity & manages
to achieve the CEV Stage IV norms value efficiently without

after treatment. 2 A fuel efficient engine with CRDI Technology- low SFC,
16 valves effort and improved swirl for cleaner combustion. 3 Higher performance due to high torque at low speed.
EGR with 2 stage cooling mechanism and turbocharger with
Waste Gate Technology (WGT). 4 High swirl design for better combustion, no after
treatment required. 5 Sturdy design of bedplate, robust fuel filtration system and
IP69 connectors make the engine durable and reliable. 6 The engine is designed and tested rigorously to adapt to
Indian conditions for more than 1,00,000 cumulative hours. 7 Common Rail Direct Injection (CRDI) technology saves
fuel, gives more power and cleaner emission norms. 8 High performance and more power with turbocharger. 9 Highly effective sensors to continuously monitor
engine health.
