Photograph of a Finn mulching machine demonstration. A Finn Klodbuster consisting of a series of chains with picks, which revolve around on swivels as it is being pulled. A variable weight slope wheel keeps the chain at an approximate right angle to the towing vehicle on slopes 3:1 and steeper. ¾ inch reinforcing steel picks with blunt ends are best for loose, coarse textured soil and for renovation work. OK-215-12.

Photograph of a Finn mulching machine demonstration. A Finn hydroseeder in operation. The nozzle tower permits accurate spreading of mixture, 360 degree-swing with a 90 degree vertical travel, carrying a distance of approximately 100 feet. Seed and fertilizer were mixed with water in the agitator tank. Alvin M. Clements, Area Conservationist, Clinton, Oklahoma, Operator. OK-214-8.

Photograph of a Finn mulching machine demonstration. A Finn mulch spreader is applying mulch at the rate of 1-ton per acre, following the initial seedbed preparation. The operator is Fred Whittington, Range Conservationist, Elk City, Oklahoma. OK-215-1.

Photograph of a Finn mulching machine demonstration. A Finn Klodbuster consisting of a series of chains with picks, which revolve around on swivels as it is being pulled. A variable weight slope wheel keeps the chain at an approximate right angle to the towing vehicle on slopes 3:1 and steeper. Here the Klodbuster is being used to spike or tie down a straw mulch. The unit should be long enough to cover the area with one through [sic] to avoid leaving a deep track on the dam made by the wheel at the end of the chain. OK-215-3.

A variable weight slope wheel keeps the chain at an approximate right angle to the towing vehicle on slopes 3:1 and steeper. Here it is being used to prepare a seedbed before applying a hay mulch. The unit should be long enough to cover the area with one through [sic] to avoid leaving a deep track on the dam made by the wheel at the end of the chain. OK-215-5.

Photograph of a Finn mulching Machine demonstration. A Finn mulch spreader applying mulch at the rate of 1-ton per acre, following seedbed preparation. Feed chute is adjustable to load heights for bales materials. Side extensions are furnished for loose material. The mulch is spread by a 24 inch centrifugal fan, powered by a 36-HP motor at 2200 rpm. Discharge head has a 360 degree horizontal swing and a 75 degree vertical swing. The operator is Fred Whittington, range Conservationist, Soil Conservation Service [SCS], Elk City, Oklahoma. OK-215-2.
