JCB has smashed Britain's fastest tractor speed with a modified Fastrac tractor.

The previous record for Britain’s fastest tractor speed was 87.27mph (140.44km/h), set by Top Gear’s Track-Tor back in March 2018.

JCB reached 103.6mph (166.7km/h) with its modified tractor.

The location for the record-beating run was Elvington Airfield, near York, where the tractor was piloted by TV presenter and motor cycle racer Guy Martin.

JCB has been working on this project over the past few months, developing the tractor for such an attempt, which was regarded an “amazing achievement” by JCB’s chair Lord Bamford.

“We’ve long harboured a dream to attempt a speed record with the Fastrac and the whole team has worked tirelessly to achieve this amazing result," he said.

"I’m extremely proud of what they have achieved in such a short space of time.

"It is British engineering at its best and it really does highlight the skills and innovation we have in our engineering team.”

Exactly 28 years to the day when the first production model rolled off the line, this new record was set.

The idea of developing a tractor that had a high road speed and capable of field work was always an idea of Lord Bamford’s.

The JCB fastrac reached a speed of 103.6mph (166.7 km/h) on Elvington Airfield, near York.

The record-breaking tractor is based around the Staffordshire-based firm's standard tractor, powered by a 7.2-litre six-cylinder DieselMax engine produced in house in Derbyshire.

Capable of churning out a massive 1,000hp and 2,500Nm of torque, the machine has been lightened to an unconfirmed weight rumoured to be in the region of 5,000kg.

Along with transmission changes and enhanced aerodynamics, this, with the help of William Advanced Engineering, made the record possible.

JCB is no stranger to land speed records, having set the fastest land travelling speed for a diesel engine in 2006, which still stands today.

That record was broke using JCB’s very own DieselMax engines, recording a speed of 350.092mph (563.41km/h) on Bonneville Salt Flats in the USA using two of these engines in what was known as the JCB DieselMax Streamliner.
