This is the John Deere 9510 "Maximizer" grain combine assembled model. The model features a removable "header" (for you non-farm types that's that thing out front with all those "fingers") and removable wheel/tires assemblies for use as a load for a truck or rail car. Expected price is around $25.00 (not finalized yet). Our representative at the Chicago MRIA show says this is a really super model. For an overhead view, click here.
