Pull-Type Corn Picker Made From Uni-System
Roger Montag, Rodman, Iowa, converted a 702 Uni-System power unit into a pull-type, pto-powered corn picker for his neighbor.
"A fire burned out the engine compartment and the transmission was going. So, we removed the engine, radiator and cab, and cut off the back wheels so we had just the basic frame-work left," says Montag.
"To the frame we added a tongue built heavy out of 7-in. square tubing. The tongue swings back under the header for road transport. The tricky part of the conversion was powering the rig. We ended up using a right angle gearbox taken off a stalk chopper and powering it off the tractor's 1,000 rpm pto. We put on a larger belt pulley, but were able to use the same belts and tighteners. None of the other drive components on the machine had to be modified. The elevator and the head's raising/lowering action are both powered off tractor hydraulics.
"To get the machine to pull properly, we moved one wheel back so now the machine trails well even in mud. Our neighbor uses the rig to pick corn with New Idea's husking unit and 4-row corn head. He's also toying with the idea of putting on a bean head in the future," says Montag.
He notes that since the unit's frame is the same as the original machine's, his neighbor should be able to put on any of the other Uni-System components.
