JCB Fastrac

The JCB Fastrac is a high speed agricultural tractor series manufactured by JCB Landpower, part of the J. C. Bamford group of companies.

Production began in 1991, with continual development to the present day. Generally the maximum speed of most models is 65 km/h (40 mph) but other speeds both slower (40 km/h) and faster (80 km/h) are produced.

All models have six cylinder diesel engines. Initially supplied by Perkins Engines then Cummins, the current suppliers are AGCO SISU Power.

Three different gearboxes have been fitted to the Fastrac in production.

All models are selectable four-wheel drive. The rear axle is driven as standard and drive to the front axle selected by the driver, through a hydraulically controlled clutch. This clutch is sprung on to give four wheel drive and hydraulically disengaged to give two wheel drive.

Most Fastrac axles have a central differential and epicyclic gearing reduction units built into the hub ends, where the wheel bolts.

The 7000 Series rear axle has a central differential and has in-board epicyclic gearing reduction units.

A standard locking differential is provided in the rear axle of all machines.

100, 1000, 2000 and 4000 Series machines have a Detroit No-Spin style differential lock in front axle.

3000, 7000 and 8000 Series machines have a driver controlled clutch pack engaged locking differential.

A two speed power take-off (PTO) is standard at the rear and a factory option at the front. Depending on the model either speeds of 1000/540 or 1000/750 are available.
