Fold up pit prop fits through an 8 inch hole
"It far surpasses the performance of any other pit agitator on the market," says Neil Dornbusch, distributor of the new Rotak fold-up 26-in. dia. prop agitator that fits through an 8-in. opening.
Pto-powered by a minimum 75-hp. tractor, the 3-pt. mounted machine's prop blades simply fold forward while it's lowered down into the pit by a hand-operated winch. As the shaft begins to turn, centrifugal force causes the blades to extend into their full 26-in. dia. width.
"So far as we know this is the first full-size prop-type pit agitator ever developed. It can move as much as 70,000 gal. per minute, completely agitating an area 40 to 50 ft. wide and up to 100 ft. long," says Dornbusch.
The prop shaft can be extended down at up to a 50? angle thanks to a double U-jointed pto shaft. Besides use in hog and dairy barns, the new Rotak Prop can also be used in open lagoons. The standard 10-ft. long shaft can be custom-built to longer or shorter lengths. The new Rotak agitator sells for $2,885.
