Video: CLAAS Lexion 780TT Combine Harvesting WheatIn this video we spend time out in the field with a CLAAS Lexion 780TT Combine harvesting wheat in Western Kentucky. This 385 bu. combine is harvesting wheat with a new for model year 2019 40ft CLAAS 1230 Convio Flex Draper Head. In this video the CLAAS Lexion 780TT unloads grain on the go from a 29ft unloading auger at 3.8 bu. per second with a 517 hp CLAAS Xerion 5000 4wd tractor pulling a 1050 DEMCO grain cart.
