With about 100 people watching - from supporters to the simply curious - Neil became only the second shearer to average a sheep a minute or quicker in an adult Merinos record attempt.
In the nature of world record shearing, among the significant team of helpers on Saturday was Lou Brown, originally from Hawke’s Bay and who in the same woolshed four years ago shore 497 at under 58 seconds a sheep to break the record for eight hours.
There were at least six others in the support team with record credentials - which Neil said was instrumental.
“We could not have done this without them.”
One was father Roger Neil, who sold his own shearing run in Taumarunui last year, and is currently “helping out the boys” in Western Australia.
Neil couldn’t have been prouder, saying he was even more proud than when he was part of a successful four-stand strongwool lamb world record himself in New Zealand 16 years ago.
Another was Cartwright Terry, originally from Cambridge and who with brother Michael set a two-stand Merino ewes record for eight hours which still stands after 20 years - one of 57 record attempts “Carty” has been to over the years, more often than not as one of the crew.
“I’m addicted,” he confessed.
It was to have been a solo bid only, which Neil and Terry agreed could have seen it go 20 ewes or more higher, with the better selection of sheep.
But the course changed when Floyde Neil decided two to three months ago that he wanted to also claim the vacant two-stand record, needing double the number to be selected from the target flock.
Terry said before the record bid that while the nine-hour day is barely a feature of Australian shearing any longer, “both boys” were capable of 550 or more, and in time the record could go over 650.
“But let’s be realistic, let’s set a two-stand world record and then hopefully they shear more than 530 each to secure a solo title,” he had said.
With nine-hour days in the woolshed all but confined to the past, it was Neil’s first in Australia, and his first anywhere since a day near Rotorua about seven years ago, while Levi Neil had never before shorn a nine-hour day.
Neither of the new record-holders had previously done more than 500 ewes in a day, on either finewool Merinos or the more tally-friendly strongwool types more common in New Zealand.
Floyde Neil has been shearing since his teens and entered the record books in November with a crossbred lambs record, which stood for less than three months.
Married with two children, he is looking at options for further records - possibly another crossbred lambs bid later this year.
He’s also planning as many as six trips to New Zealand next summer for the national shearing circuit, with a target of winning the right to represent New Zealand in the annual home and away transtasman shearing tests.
But there is the issue of the back pain, which his father said was evident beforehand, and which the record-breaking shearer says needs a couple of weeks off before shearing again.
Levi Neil, despite the family history in shearing was a comparative latecomer, working in the meatworks for Silver Fern Farms in the South Island before turning his hand to the woolshed.
But he seemed happy enough that his brother had given him the chance.
It never seems too late for one curious spectator, in Peter Ledger, who travelled more than three hours from Mundaring, near Perth, to check out the quality of the shearing.
“It was very inspiring,” he said. The 67-year-old only took up shearing less than four years ago, because he was retiring from farming.
“I’d like to think I could do 200.”
For the record, Stacey Te Huia shore 113 in the first two hours of his February 2015 record, followed by successive 105-minutes runs of 103, 105, 104 and 105.
On Saturday, Floyde Neil shore runs of 121, 105, 105, 106 and 103,while Levi Neil shore runs of 115, 103, 100, 104 and 104.
Judging convenor Alistair Emslie, of Kurow, said Floyde Neil had had one “reject” during the day and Levi Neil four, as the panel of four kept a close watch on the quality.
Floyde Neil had an average quality rating of 16.74, and Levi Neil 17.24 - each within the limit of 18 penalties.
