The Art Deco Trust also stepped in with a $500 donation to take it up to $2000.
And at the end of the race seven-year-old Kalle Tremain took the chequered flag to the delight if his dad and crew.
"He was pretty confident he could do it," Mr Tremain said.
"And we've got a pretty speedy cart."
That win boosted Tremains' Art Deco Festival assistance for the trust as the Hastings Hamper Auction they sponsored had earlier drawn in around $4200.
"It's great because it all adds up," U-Turn Trust CEO Ana Apatu said yesterday when she got a close-up look at the winning cart.
Trust chairman Rex Graham said without ongoing community support the trust would not be able to go on.
"We have to have the resources to do what we do," he said, praising both the approach and devotion of the unpaid trustees and teams of volunteers as well as the many community and business groups who stepped forward to ensure they had the funding to operate.
The trust assists struggling families in Flaxmere through one-on-one assistance programmes as well as helping steer schemes like the community garden and the 'Jarmy Army' where youngsters in need were gifted warm new winter pyjamas.
Art Deco Trust general manager Shane Gorst said the sponsors race event would be repeated next year.
"Yep, we'll do it again - it is all about supporting communities," Mr Gorst and the derby event was very family and community-based so was a good fundraising fit.
Although at the time he said it was a part of the festival which had gone "right down to the wire" as heavy and persistant rain swept across the region on the Friday and Saturday.
"The night before there were times we did not think it was going to happen - but we got a good day after all."
