People had travelled from Tauranga, Te Awamutu and the Waikato to be involved in the day, he says.
He says the working day encompasses everything, including sheep shearing, stock cars, ploughing, a bouncy castle for children, a swap meet and Clydesdale horses doing ploughing.
Eric says there were also a few classic cars at the event, and this year was the first time there had been music.
"It's great to see old gear being restored and reused... and the young ones don't realise how this all started out.

Eric says the Rotorua Tractor and Machinery Club is also trying to attract new members, especially younger people.
He says the club has meetings once a month and organises a few tractor treks, along with the annual working day.
Rotorua's Glen Lennane says he decided to take his two sons along to the annual working day to get them involved and as something fun for them to do on a Sunday.
He says they had arrived at the event early and had been enjoying all of the old machinery.
"This is our second time here... I would probably come back too, because every time you come back there's something different.
Dylan Lennane, 9, says he enjoyed watching the cars driving, and Matt Lennane, 11, says it was cool getting to take a spin in one of the cars and go pretty fast.
