A new Guinness World Record has been set for the most combines working simultaneously in the same field, in southern Manitoba, Canada.

Of the 306 machines registered to compete, a total of 303 combines completed the five minutes needed to secure the attempt as valid, with Guinness adjudicator Philip Robertson determining that three didn’t complete the allotted time slot.

Organisers of the Harvest for Kids event were aiming for 300 combines to raise awareness and funds for Children’s Camps International (CCI).

Combines of all makes and models — ranging from a 1957 Massey Ferguson right up to brand-new machines —  started on the outside of the field, which spanned nearly a mile in length, all cutting towards the finish line in the middle.

The previous record of 244 combines was set by the same event organisers in Dalmeny, Saskatchewan, in 2012.
