Allan Dippie’s headline-making sale was a "white glove auction", one in which every lot on display is sold.
There were 139 tractors available over the weekend, and buyers from across the country flocked to place their bid as some machines sold for over $30,000.
Mr Dippie said interest in the auction had been high from the beginning, but he was still surprised that not a single tractor was left behind.
"The amazing thing is some of these tractors have ended up all around the North Island, all around the South," he said.
"They've gone to every corner of New Zealand, just about, and a few locally, which was nice."
The auction, run by Dunedin auctioneers Proctor Auctions, went live online weeks ago. The final day was an in-person event at Central Machine Hire last Saturday.
It was described by Mr Dippie as a social day, with many people using the occasion to connect with other tractor enthusiasts.
It attracted a range of interest from those who wanted a tractor to use on their lifestyle blocks to the keen collectors who wanted a new addition to their own collections.
One of the highest-selling tractors was a mid-1960s Ford County tractor which was auctioned off for $34,000.
Other memorable sales included a John Deere tractor sold to a collector in Taranaki who planned to display it at the Maketawa John Deere Museum.
"It's definitely a hobby that's alive and well," Mr Dippie said.
"There were several that sold in the $20,000 range and a whole lot that sold in the $10,000 to $20,000 range."
There were also some that sold for less than $1000, mostly to those who wanted a restoration project.
Some had attended the auction simply to take a look at the large collection, as Mr Dippie rarely opened it to the public.
Despite being cleaned out of many tractors, he said he was not too sad to see them go, as he had more than 200 still left in his collection.
"I didn't get too much seller's remorse ... we've got space to move and so now we're going to concentrate on restoring a few tractors.
"It’s just made a whole lot of space."
Mr Dippie said he wanted to refrain from adding to his collection, saying he just wanted to focus on maintaining the tractors he had.
He was still keeping his love for tractors alive and well, as he planned to attend an auction in Invercargill this weekend — but promised he would not be buying anything.
"I'm just going as a spectator," he said. "It’s under control."
