The Versatile 1080 (known as Big Roy) was built in the late 1970s as a prototype. It weighed 26 tons, and came with a 600 hp, V-12 19-litre Cummins engine and eight-wheel-drive on four axles. A 2100 litre fuel tank was in the front section.
Due to its large size, 120-degree wide angle television cameras were linked to monitors in the, in order to allow the farmer to view the implements hooked behind.
Fuel consumption? At the time, there were no implements big enough to challenge its pulling power, so no accurate tests were ever done. Soaring development costs and a small market for the huge tractor forced cancellation of production, but Big Roy is still on display at the Manitoba Agricultural Museum in Austin, Manitoba, Canada.
