"It works great," says Nebraska hog producer Dale Harlan, of Hickman, who built his own manure lagoon stirrer-agitator.

The main frame, 24 ft. long, is made from a 4 by 8-in. I-beam. The 1 1/2-in. dia. drive shaft rides on three oak pillow blocks and rotates at about 1,300 rpm's. It's pto-drive was salvaged from a silage blower. Plate steel (3/8 in. thick) was used to make the 30-in. dia., 4-blade propeller. The 3-pt. mounted hitch's top linkage can be adjusted, via a chain, to hydraulically raise or lower the propeller end about 4 ft.
