Abstract

Corn stover harvest in Iowa was studied using a single-pass combine and baler configuration over the last three years. The combine experienced a productivity loss from pulling a baler through the field of 6-10% depending on field conditions and speed. The additional biomass harvested by the combine lowered productivity depending upon the harvest rate and yield of the biomass. At the 1.4 ton rate in 2011 fall harvest the average maximum productivity loss was 25-30%. The loss was experienced in experiments without factoring in grain logistics. A model was developed to look at the field logistics of the grain cart to and from a single-pass combine when unloading on the go. The model showed that only a 16% loss in actual productivity when compared to a conventional combine which unloaded on the go as well.
