Home-Built 25 Ft Air Reel
"We needed an air reel last summer because we could see that the crop was going to be short," says Bernard, who notes that the brothers farm about 3,200 acres. "Commercial air reels cost about $3,500, but we built ours for $1,700 and we built it the way we wanted it. It works great in short crops and equally well in tall, heavy crops. We saved 3 to 5 bu. per acre. Any grain that falls onto the cutter-bar is blown into the header. Bat reels work alright in tall crops but in short crops some grain lodges behind the cutterbar and because the straw is so short the batt reels can't reach it. An air reel doesn't need straw to work. We can clip even short crops just below the grain heads. Also, the visibility is great. We can see just as well at night as during the day."
The Martins bought the 18-in. dia. blower and mounted it on the right side of their Case-IH 1010 header. The blower is powered off the sickle drive shaft. They used a series of belts and pulleys to speed up the blower to run at 4,200 rpms and enlarged the blower's throat dia. from 4 to 6 in. to increase air volume. Air goes through a flex-tube into a 25-ft. long, 6-in. dia. steel manifold mounted on the reel arms and out nozzles spaced 10-in. apart (five nozzles in front of the feederhouse are spaced 8 in. apart). The curtain of air pushes the crop into the header. A shroud covers the fan inlet to keep straw and chaff from entering the fan.
The Martins used an oversized sprocket to slow down the feeder auger to make sure it doesn't throw grain heads out in front of the combine. "An air reel has no batts to hold the crop in," notes Bernard.
To make the downspouts, which are curved toward the cutterbar, the Martins cut a 1 1/4-in. dia. hole every 10 in. in the manifold and welded the downspouts in. They welded a 1 by 1/4-in. strip of metal inside the middle portion of the end of each downspout. Then they flattened the end of each downspout and cut it in a V-shape to shorten the sides of the downs-pout tip, ensuring complete air coverage between downspouts. "We use a manually-operated pivot to move the manifold back and forth and a hydraulic cylinder operated from the cab to move the manifold up or down," notes Bernard.
