A method for the debottlenecking of grain harvesting and grain bagging comprises a set of steps. Grain is transported in a grain cart from a harvester at a harvesting location to an accumulation site. Grain is bulk unloaded crop from the grain cart at an accumulation site by, for example, gravity dumping through a rear door of the grain cart. The cart returns to the harvester; and the grain at the accumulation site is transferred into a silo storage bag. The steps of transporting the grain, bulk unloading the grain, and returning the cart comprise a first process. The step of transferring the grain from the accumulation site into a bag comprises a second process. The first process and second process proceed in parallel.
