Young said a 1959 Massey Ferguson was a particular favourite of his, having been bought brand new by his father early in the life of the farm.
There had been many changes in the industry over the years, with the shift from taking produce to market twice a week in the early days having shifted to daily markets.
That move had shifted risk from the supermarkets back on to farmers.
"This used to be sort of a lifestyle business, but as the years progressed it turned more into a business."
Auctioneer Rob Fowler, of Rural Livestock, said the auction was a total clearance, and all 10 tractors had sold "and to good homes".
Young's father's 1959 Massey Ferguson tractor sold for $10,500, plus GST.
There were 368 registered buyers present, with people travelling from as far as Nelson in the north to Bluff in the south.
Saturday's auction represented an end of an era in Outram, Fowler said.
"That's the last Chinese grower on the Taieri. From 24 growers to none."
