He acquired a McCormick-Deering Farmall as it reminded him of the tractor his father bought to replace the six-horse team used on the family's Otepopo property.
Mr McMann drove that team when he left school at 13 before moving on to a different form of horsepower.
He had enjoyed his vintage machinery interest, picking up tractors from all over the place, including one from Stewart Island.
He had attended many vintage machinery rallies, transporting his tractors as far afield as Thornbury in Southland. His tractor collection numbered ''about 12 or 14 or something... ''.
Mr McMann was unsure how much interest the sale would attract, saying vintage machinery clubs were ''not like they used to be''.
However, he knew of intending purchasers coming from as far away as Blenheim and there had been calls from the North Island.
''We should have a wee bit of patronage, [but] you wouldn't know,'' he said.
Some of the tractors had new motors and he still had a box of new valves his brother got from the United States for him about 30 years ago.
