Williams farmer Noel Fowler, of Aubrey Fowler and Co, says his family has two weeks of harvest to go. They only finished baling hay on Friday.
Rain in November delayed their start to harvest, with more than 150mm recorded since then.
"We have had plenty of good harvesting days and the rain has probably held us up seven to 10 days," Noel said.
"We normally would go 24 hours but the moisture has been making it hard to harvest into the night.

"We've also been bogged up to 10 times in one day, and you get bogged at least a couple of times a week."
Noel said parts of paddocks were too wet to harvest.
"I can't remember harvesting this long but my brother William remembers going back to school in February when we where still harvesting, which was probably 20 years ago," he said.
While the State record for CBH has been broken, Noel said the 2011-12 season would be an average year for the family due to the late break and late harvest.
"Our biggest yielding years are when we get 450mm of rain at the right time," he said.
