The U-2 reel is very poor for reeling in light short crops, as the fingers go through the crop, and the bats dont make contact. It makes me want to get an air reel, if I could afford one. Ray Stueckle in his book Setting your Rotary Combines for Better Harvesting suggests extending the bats to within 3" of the ends of the pickup fingers with sheet metal that goes down one side of the bat, around the fingers (with holes for the fingers to poke through) and back up the other side of the bat. Along the same vein, about 10 years ago, the custom operators around this area were using 6" plastic drainage tile around the bats, with the fingers poking out the bottom about 3" as well. In recent years they switched to air reels. This year, I tried using 1_8" thick HDPE (High Density PolyEthylene, also known as puck-board) to make up bat extensions down the crop side of the bat to within 3" of the ends of the pickup fingers. I attached the material to the bats using sheet metal screws with backup flat washers every 6" or so. My wheat was very short and light this year, but fed very well despite the short 5" average cut-offs - an impossible situation with the U-2 reel alone. The HDPE is very slippery and there was no visible wear, compared to galvanized sheet metal that Ive tried in the past, which ended up rusting in the wear areas.
