The Hose Mod should work fine for any standing crop. The shorter the crop, the more of an improvement it will make in feeding. You will want to bring the reel "aft" or backwards untill it continuously clears the crop from the cutter bar as soon as it is cut off. When the crop is taller, the primary benefit to the hose will be to block loose beans from rolling out the front of the header. For crops that are lodged and flat on the ground, such as wheat with too much nitrogen, you need the reel moved forward to stand the crop up before the cutter bar cuts it off. In this case, it is better to remove the hose. This will help minimize the bunching behind the cutter bar. Since you can't have the reel in two places at once (fore and aft) the hose fails to help when you need the reel in the forward position. luckily, it only takes a few minutes to remove or reinstall the hose, so setting the header up for the crop conditions is quick and easy.
