Dave Clancy and his daughter Erin will take their 500 horsepower Mini Modified to the Australian Tractor Pull Championship grand final on Easter Saturday.

For Mr Clancy it will be a silver anniversary - a quarter of a century of competing at Quambatook, where his best result was second place last year. The 50-year-old is hoping to do much better than silver this time.

"We're not exactly a high budget team but this year will be our biggest year yet," Mr Clancy says. "We've got a lot more power this time. The challenge is to harness all that power.

"I love it. The adrenalin rush. There is nothing more exciting than a full pull. You know you're on the edge when you still get nervous after a quarter of a century."

Erin Clancy started tractor pulling at Quambatook when she was 16. She is now 24.

The father-daughter team shares the same tractor but are entered in different weight classes.

Mr Clancy built 2Tuff in 1990. It is like grandfather's axe, though, in that virtually every bit has been replaced at least once over the years.

2Tuff is powered by a 350 Chevrolet V8 which, in its 2015 trim, has more than 500 horsepower (370kw of power) and mountains of torque. Not bad for a machine weighing a mere 750kg.

"With that much power and so little weight, anything can happen," Mr Clancy says.

"I've had some wins and top three places here and there but my best result in the national championship is fifth overall. I'll retire when I win it. Who knows? That might be next year."

Apart from being the local postman Mr Clancy also has a small beef cattle farm.

Erin, meanwhile, is a "burger technician" in Colac. Mr Clancy says there are about 10 major tractor pulling events over the course of the year but Quambatook is like the "Bathurst 1000" of the calendar - the one everyone wants to win.

Carngham's Russell and Stephen Schmidt are also heading up to Quambatook to compete with "Pacman" in the Super Mini Modified category. They've endured a very tough season to date but are hoping to "Steven Bradbury" a good result.

Competition starts at 1.30pm at the Quambatook Tractor Pulling Complex on Saturday and will conclude under lights at about 10pm. Classes include vintage, two-wheel-drive and four-wheel-drive farm tractors, in addition to the purpose-built modifieds.

Adult entry is $25, children 10-15 $5 and under-10 free. A family ticket is $60.having
