Revolutionary Combine Sieve Stops Grain Loss,Boosts Capacity 30%

Revolutionary Combine Sieve Stops Grain Loss,Boosts Capacity 30% COMBINES Accessories 18-1-24 "We think it's one of the biggest improvers of combine performance ever developed," says Franz Greisbach, North American distributor of a revolutionary new combine top sieve that developers say almost totally eliminates grain loss out the back end, is virtually plug-proof, and boosts capacity of both conventional and rotary combines up to 30%. "As every veteran combine operator knows, the problem with most conventional top sieves is that chaff and grain coming out of the cylinder build up on the top sieve, forcing you to slow down until the jam clears so as to avoid excessive grain loss out the back," Greisbach points out. The new-style top sieve, developed in Germany by Schumacher Manufacturing, is designed with two extra steps in the back to break up the flow of material to prevent bunching. Further protection against bunching is provided by redirected air flow. "The new Schumacher sieve allows you to increase wind speed by 10% - without blowing grain out the back, as happens when you try to increase wind speed with a conventional sieve," explains Greisbach. "If you're now harvesting with 1% grain loss, the new sieve will allow you to travel up to 30% faster and still maintain no more than 1% grain loss. "One of the first things you'll notice when using the new sieve is a dramatic reduction in the amount of material coming through the return elevator," notes Greisbach. "That's because the new sieve diverts more grain to the bottom sieve, and more cleanly-threshed chaff out the back." Installing the new sieve is as simple as installing a conventional top sieve. When you trade combines, you can remove the Schumacher sieve and install it in the new machine. For hillside operation, the new sieve can be equipped with optional bolt-on flanges which help keep material from bunching up on steep slopes. Greisbach says cost of the new sieve, which has undergone extensive field testing in Germany in a wide variety of crops the past two years, will be 15 to 20% more than a standard top sieve. "It's in production and will be available for most makes of combines - both rotary and conventional - on a limited basis in Canada and the U.S. for the 1994 harvest season," according to Greisbach. "We'd especially like to hear from farmers or custom operators with unusually stubborn unsolved top-sieve problems."
