"I looked along the road and saw the fence lying in the paddock.
"The car took out over 100 metres of fence, eight posts and battens. The culprits did not leave a message."
She said the culprits were lucky they hadn't hit the fence about a metre back because they would have crashed into a gully and a pipe.
The crash vehicle had towed the fence through the paddock, knocking down another fence in its path.
"It wrecked the fence that was around a tree. That broke their rear-vision mirror, which I was quite happy about."
The woman found pieces of the smashed mirror on the grass and had looked for bits of the vehicle to determine its colour, but had found nothing.
"We have been asking locals if they have seen anything but we haven't found anything out yet."
It was "lucky" no animals had been hurt because the woman had initially planned to move her 15 ewes into the paddock that day.
It was the second time the woman's fence had been "wrecked", in the same spot, but the previous driver had fronted up and paid for the repairs.
She said she had already asked the district council to put a "slow down" sign on the corner next to her property, where a crash had happened.
"People come around the corner too fast, lose control and swerve on to the right-hand side of the road and into the fence."
A council worker was out evaluating the road on Wednesday, the woman said.
"I'm really annoyed because it's a costly business if you have to pay for the fence to get repaired all the time."
