JCB FASTRAC SPEED RECORD 
 had to stand up on the Allis  
 Chalmers tractor because of its lack  
 of stability. Guy Martin described  
 the record-breaking Fastrac as “rock  
 steady”, whereas Jenkins likened his  
 experience to “riding a frightened  
 bison”. Jenkins did claim,  
 however, that it was one  
 of the most thrilling  
 experiences of his  
 life despite the  
 fact he had raced  
 cars at more  
 than 200mph. 
 Jenkins’  
 record stood  
 until February 19,  
 2015 when   
 rally driver Juha  
 Kankkunen drove a  
 Valtra T234 at 80.88mph on  
 a snowy and icy emergency airfield  
 in Finnish Lapland. Kankkunen had  
 to rely on the world’s first winter  
 tires for tractors, the Nokian  
 Hakkapeliitta TRI. After the Finnish  
 record, tractor speed attempts  
 became more common. Just a few  
 months later, on September 25,  
 2015, US racing driver Jack  
 Donohue set a new world record of  
 96.3185mph on his 8N Credible  
 tractor on the Bonneville Salt Flats.  
 The 1952 Ford 8N farm tractor had  
 been designed to go at 12-14mph,  
 but Donohue added aircraft tires at  
 the rear and land-speed racing tires  
 at the front, then installed a larger  
 version of the Ford Flathead V8  
 engine. He returned the next year on  
 September 17 to beat his own world  
 record with a speed of 101.1692.  
 The accreditation of records is  
 complex, however. Donohue’s  
 34 iVTInternational.com September 2019 
 time was attested by the  
 East Coast Timing  
 Association  
 (ECTA), but   
 it was not  
 recognized   
 as a Guinness  
 World Record.  
 Therefore,  
 when Top Gear’s  
 ‘Track-Tor’  
 reached a speed of  
 87.2mph in March  
 last year in front of a  
 Guinness adjudicator, it  
 was acclaimed as a new Guinness  
 World Record. To hit this speed, the  
 Top Gear team added a 5.7 litre  
 Chevy V8 engine, four-wheel brakes  
 and adjustable air suspension. 
 Race for the prize 
 From JCB’s perspective, the Top Gear  
 time was a British record, but not a  
 world record. The next step,  
 therefore, is to overtake the world  
 record set by Dave Archer, a beef  
 farmer from Ohio, last winter.  
 Archer emulated Donohue by  
 supercharging a 1960s tractor which  
 originally had a top speed of  
 13.9mph. Archer had the idea of  
 while recovering in hospital from  
 double lung surgery. On returning  
 home, he got his old Allis Chalmers  
 tractor out of the shed and added  
 specialty tires, a roll cage, a flywheel  
 shield and a parachute. He spent a lot  
 of time modifying the engine, but he  
 claimed that the engine, transmission  
 and almost every other component  
 was original to the tractor. Archer’s  
 daughter, Cathy Shalitz, reached a  
 speed of 108.5mph in October 2018  
 at an event held in Arkansas by the  
 East Coast Timing Association.  
 JCB’s Alan Tolley is confident his  
 team can surpass the 108.5mph  
 mark by the end of the year. “We’ll  
 be analyzing the data from the  
 British record at Elvington, and  
 there are definite improvements we  
 can make. We can add more power,  
 but you can sometimes hit a brick  
 wall and we’ll need to consider the  
 resistances and aerodynamics,” he  
 says. To keep hold of the record,  
 however, the Fastrac may need to go  
 significantly faster than 108.5mph.  
 World record holder Dave Archer  
 told Farms.com that his modified  
 Allis Chalmers tractor could go  
 much faster. “I built it with the idea  
 in mind it would be like a 250 to  
 300mph car. If someone breaks our  
 record, we’ll be waiting,” he said. iVT
