Name: Wintersteiger/Kemper head biomass harvester (7.5 ft):

• Is a Tractor
Description: A Kemper chopper head (7.5 ft cutting width) mounted to the front of a John Deere 7330 tractor with a Winterstieger Cibus TRM weighing container mounted to the back 3 pt hitch of the tractor. 22,340 lbs was the total weight of all 3 items together: JD 7330 had less than a 1/4 tank of fuel when these equipment items were weighed. This is used to harvest biomass and grass micro plots, it then chops the grass up and blows it over the tractor to the bin on the weigh platform.
