WASHINGTON, Maine — The swishing of handheld blueberry rakes wielded by dozens of field workers is being replaced by the rumble of tractors across Maine's wild blueberry fields as growers turn to mechanical harvesters to pick the lucrative crop.
A decade ago, about 20% of Maine's 60,000 acres of blueberry fields were harvested by mechanical means. Today, it's about 80% as growers discover that it's cheaper to replace hand pickers with more efficient machinery.

Here on a gently sloping hill off a remote dirt road, two John Deeres move slowly through a field, mechanical contraptions hanging off one side raking the fruit off low-lying bushes. Walter Degreenia drives one of the tractors as his wife, Gail, stands on a back platform sorting through the berries as they are carried on a conveyor belt and dropped into crates.

"On a good day, I can harvest 10,000 pounds with one machine," Degreenia says.

That's about 10 times what a typical person can harvest in a day with a handheld rake, swiping it through the bushes over and over for hours on end.

Maine's wild blueberry industry, which dates back to the 1840s, counted on hand-pickers to get the crop for more than a century — long after growers of other major crops turned to tractors and sophisticated harvesters.

But with the yearly harvest averaging about 70 million pounds a year — up from under 20 million pounds before the 1980s — wild blueberry growers have had a hard time finding enough people to pick all those berries.

Wild blueberries grow naturally in Maine and eastern Canada. They're different from cultivated berries, which are larger and grow on high bushes.

About 40 to 50% of cultivated blueberries are hand-picked but the mechanization trend is happening in the dozen states where they're grown, as well, said Frank Bragg, chief executive officer of the Michigan Blueberry Growers Association.

In the old days, Maine's blueberries were harvested by local residents, including school kids and Indians from Maine and eastern Canada.

These days, growers turn mainly to migrant workers from Mexico and central American countries to fill the void. But with labor in tight supply, growers have also been turning to mechanical harvesters.

"Right now, you can't even get migrant workers if you want them, so that's what's driving this," said David Yarborough, a blueberry specialist and horticulture professor at the University of Maine.

Maine growers like mechanical harvesters because they don't have to manage hard-to-find workers and deal with government paperwork. The machines also result in lower production costs — adding to the bottom line.

The early models often destroyed plants and had low yields compared to hand-pickers. But the newer models are efficient with high yields.

And as the machines have improved, the state's blueberry growers have flattened and removed rocks from thousands of acres of fields to make them suitable for mechanical harvesters.

Nat Lindquist, vice president of operations for Jasper Wyman & Son in Milbridge, said half of his company's 7,000 acres are harvested mechanically. Some blueberry growers, he said, don't use hand-rakers at all any more.

"Over the years, the manufacturers have added more bells and whistles that have improved the quality and are picking most of the fruit," Lindquist said. "Prior to the improvements, they left a lot of the fruit on the ground."

Degreenia's two tractors plod along at less than 1 mph as they make their way around the field, harvesting two to three acres a day on average. In a nearby field, Haitian workers bend over the bushes with their rakes, scooping up the berries the old-fashioned way.

Degreenia has raked berries or worked as a crew leader since he was barely a teenager. With mechanical harvesters, the work is less tedious, easier on his back and more profitable.

"This is great compared to what we used to do," he said.

At the end of the day, the berries from this field are taken by truck to Coastal Blueberry Service Co., a distribution center in the nearby town of Union. From there, they'll go to Ellsworth, where they'll be frozen.

Less than 1% of the state's harvest is sold fresh. The rest will make its way to consumers in muffin mixes, yogurts, juices, cereals, preserves and other products.

Paul Sweetland, who manages Coastal Blueberry Service, said the rise of mechanical harvesters is perhaps the biggest change the industry has ever experienced.

Harvesting blueberries costs roughly 16 to 17 cents a pound by hand and about 10 cents a pound with a mechanical harvester, he said. When prices fall, the savings can mean the difference between a profit and a loss.

"This is tremendous change," Sweetland said. "This is the future."

Besides the tractor-mounted harvesters, growers are also turning to portable, self-propelled walk-behind harvesters — similar to walk-behind lawn mowers.

Zane Emerson, who sells them through his Maine Blueberry Equipment Co. in Columbia Falls, said more than 50 of the machines are now in use.

"I predict the day," he said, "when all of the blueberry fields will be mechanically harvested."

The availability of cheap manual labor has held back the development of technological solutions in this country. Throwing warm bodies at a problem is so 18th century ....

You mean to tell me that these people are not going to just sit around and watch their crops rot! Wow, who'd-a thunk it?

I would like to offer praise and support for any farmer who has chosen mechanized means for harvesting their crops. We need to see if there is any move in that direction in California, for example, where the sad song of rotting crops is being sung regularly.

Well I always though blueberries grew on trees , I could have sworn it was blueberries we use to go pick in stayton Or. OFF Of TREES.
