Rutherford grew up on the family farm, where his fascination for machinery led him to become a talented and innovative engineer.
He was the creative force behind Logic, which first burst onto the scene with a revolutionary tractor design featured on the BBC's Tomorrow's World in 1972.
The Logic Tractor caused a stir by introducing four-wheel drive and an independently-sprung cab - features that are now mainstream.
But Logic really came to prominence with the introduction of ATVs. Rutherford was instrumental in their establishment as the familiar and ubiquitous workhorse of today.
His entrepreneurial drive saw the introduction of a wide range of equipment that would exploit the new niche that had been created. As a result, he transformed working practices on countless farms in the UK and abroad.
