Disclosed is an improved articulated combine of a forward grainhead carried by a forward bogey devoid of grain storage and operated by an operator and a rear grain storage bogey capable of crabbing. Proximity sensors are affixed to the side of the grainhead and on the side of the rear end of the rear bogey. Cameras are affixed to the front of the forward bogey looking to the side of the forward bogey, to the front of the rear bogey looking rearwardly into the rear bogey grain storage, to the rear of the rear bogey, and on the grain arm discharge end. Readout from the sensors are fed to memory for each type of grain off-loading vehicle for later use by the operator in placing the combine in the optimum unloading position. Video also is fed to a display confronting the combine operator.
