In October 2019, "Fastrac Two" hit an astonishing peak speed of 153.771mph on its way to recording an average of 135.191mph at Elvington.

The record-breaking attempt was overseen by Guinness World Records, who confirmed that the JCB Fastrac completed two runs, in either direction through a speed trap set 1km apart, within the allotted time, to set the 135.191mph record.

Fastrac Two maintained the same design principles and packaging, but would be 10% lighter than its predecessor (Fastrac One), reducing its weight to less than five tonnes. The tractor’s bonnet was changed from steel to aluminium; non-structural material was removed from the chassis, while the cab and roll cage mounts would be incorporated into the chassis design.

Streamlined bodywork also had a role to play, with aerodynamic analysis and development conducted by Rob Smedley, ex-Williams head of vehicle performance, and computational fluid dynamics (CFD) used by Williams Advanced Engineering, to give Fastrac Two a 10% reduction in drag over Fastrac One.

This saw the development of new cab air deflectors, a new rear cover, re-designed radiator covers, new side panels, front bumper and cab roof, would also help the tractor to cut through the air, on its way to the new Guinness World Record.

An extra shot of power was needed, and the 7.2 litre, 6-cylinder JCB Dieselmax engine produced at JCB Power Systems in Derbyshire, also received some extra attention. A new, larger turbocharger was accompanied by water injection and charge-air cooling through ice tanks, reduced intake temperatures by 50˚C.

An electrically driven supercharger system was again used, while a revised exhaust manifold contributed to improved flow. The adoption of a sophisticated anti-lag system would also keep the larger turbocharger delivering its maximum boost pressure while gear changes took place. The result of the powertain improvements was a peak output of 1,016hp at 3,150rpm, and over 2,500Nm of torque.

Farmers and contractors around the world have a rare opportunity to share in the success of JCB’s outstanding tractor speed record by securing a Special Edition of the Fastrac 4220 and 8330. But they will have to move fast themselves – just 25 examples of each model are being produced and dealers in Europe, North America, New Zealand and Australia have been quick to place orders.

In June 2019, JCB set a Guinness World Record for the fastest tractor at Elvington Airfield in Yorkshire. Called Fastrac One, the tractor reached a speed of 166.7 kmh (103.6 mph) with motorbike racer and lorry mechanic Guy Martin in the driver’s seat. JCB then embarked on an ambitious plan to break its own record and developed Fastrac Two – which is 10% lighter and even more streamlined than its smaller brother. In October, Fastrac Two hit an astonishing peak speed of 247.5mh (153.771mph) on its way to recording an average of 217.6kmh (135.191mph) at Elvington.

For the Special Edition tractors, the unique specification, features and capabilities of the standard Fastrac are enhanced inside and out with commemorative decals and additional equipment. External enhancements comprise a distinctive chromed exhaust stack, special ‘Union Flag’ decals on the cab rear three-quarter panels, and embossed ‘JCBWFT’ lettering on the toolbox.

As operators climb aboard the spacious Command Plus cab, they are greeted with the script ‘JCB Fastrac – Word’s Fastest Tractor’ etched into the doorway kick plate and woven into the grey door-to-door carpet. This script is also embossed into the leather upholstery of the two full-size seats, which have distinctive yellow edge panels and stitching to match. Operators also have the luxury of a JCB yellow-stitched leather-bound steering wheel with a ‘Fastrac at speed’ logo at its centre.

In addition, every Special Edition Fastrac 4220 and 8330 has a commemorative plaque identifying the tractor as one of just 25 examples of each model celebrating the record, along with a certificate of authenticity for the owner.
