The Finer Details of Auger Platforms

On auger platforms, reels should be initially positioned “back and down.” At its lowest position, the tines should just clear the cutterbar if the center of the cutterbar is flexed to its highest point.

Adjust the reel rearward so its bats just clear the front of the cross-auger’s flighting. The reel should be positioned to continually feed and press crop against the auger so it can convey the material to the center of the platform.

Actual height of variable-height reels in the field depends on crop conditions. In down and tangled crops the reel might need to run at its lowest height. In tall crops under good conditions the reel might need to only run in the top inch or two of crop, but always to the rear and close to the auger.

Make sure all retracting fingers on the auger are straight and have smooth edges and there are no irregularities in the auger’s flighting or main tube.

“Augers, especially full-finger augers, can flail a lot of beans,” says Kelly Kravig, Case IH harvest marketing manager. “A lot of beans we see hitting the windows of the cab that get blamed on reel shatter are actually related to the auger.”

Augers set too high, or too far forward, encourage crop to tumble around the auger, shattering pods. Augers should be set low and back, with 3/8" to ½" clearance between
the edges of their flighting and adjustable stripper plates mounted to the floor and backside of platforms.

“Make sure the auger flighting stops at the outside edges of the opening in the feeder house,” says Jeff Gray, product coordinator for Claas Lexion. “You want the crop to feed into the full width of the feeder house. There are extensions you can bolt onto or remove from the auger flighting to match the auger flighting to the opening of the feeder house.”
