New Fastracs more fuel efficient and quieter
By Stephen Cadogan
Improved fuel consumption and reduced in-cab noise are claimed as two of the most significant benefits for end-users of new JCB 3000 Series Fastrac high-speed tractors.
The two new models are the 3200 Xtra and 3230 Xtra and they feature a number of creature comforts, as well as technological advances.A new anti-lock braking system gives proportional and smoother response for greater control on firm, loose or icy surfaces.
The new traction assist uses torque and brake control to prevent wheel spin, for example, when turning into a field gateway or pulling away on loose ground. This is designed to maximise grip and minimise tyre wear on the road.
Hill-hold is another new feature that keeps the brakes on when the driver presses and then takes his foot of the brake pedal; they are automatically released when the tractor moves off, which makes hill starts easier to handle.
The new machines come guidance ready, for easy addition of a full auto-steer system (especially useful for spraying, spreading cultivation and sowing). JCB say the Fastrac’s mid-mounted cab and smooth-riding suspension make it an ideal platform for precise and reliable use of this GPS application.
Auto-steer integrates with other automated features introduced with the Xtra specification last year — such as headland turn assist.
Adjustable flow rate and timing for remote hydraulic cylinders is available to help control big grass mower combinations, for example, using a hydraulic system upgraded to load sensing status with a variable flow 60cc pump.
The new 3000 Fastracs also offer the option of a rear camera, making it easier to hitch up and monitor close-coupled implements. There is also a new fender-mounted auxiliary spool control option for control of the new optional hydraulic top link.
New mudguards front and rear reduce the amount of water and mud splashed on to the cab and windows.
New bonnet removable panels and a service door improve access for service and daily checks. Larger steps make it easier to get in and out of the cab.
The semi-powershift transmission on the 3200 Xtra and 3230 Xtra Fastrac since mid- 2010 offers 24 forward and nine reverse ratios, with six powershift steps, automatic road and field shifting if required, and a power shuttle for easy changes between forward and reverse.
There’s a choice of manual or two auto-shifting modes, including Drive for road travel, which auto-shifts between 12 speeds. Engaging autoshift for field work will automatically select the best ratio.
Xtra-Drive on the road allows the driver ignore the clutch pedal once under way. Even when slowing and stopping, only the brake pedal is needed. But when precision control is needed to help hitch up an implement, using the clutch pedal over-rides the Xtra-Drive.
The Sisu engines increase torque has on the 3000 Series flagship 3230 from 949 Nm to 1015 Nm. Maximum power output is 172kW (230hp) for the 3200 Xtra, and 200kW (270hp) for the 3230 Xtra.
Both Fastrac models are being upgraded to 540/65R34 tyres all round as standard, and a 600/70R30 with the same rolling circumference becomes the widest and tallest factory-fitted tyre option.
