"My father and I built this self-propelled sprayer from a combine last winter in our shop," says Wilfred Berchimsry, Watson, Sask.

"We dismantled our MF Super 92 combine and, using the main frame, attached 80-ft. booms to the rear of the machine. With some reinforcing to the main frame, and a heavier rear axle, we can carry 500 gal. of water for spraying. Because the combine has variable speed, we can operate at different speeds for different rates of application. Sitting up higher in the cab protects the operator from spray drift and provides better visibility. Compaction is minimal and tracks go unnoticed 1 1/2 weeks after spraying. The Super 92 has plenty of power to handle the unit when spraying up to speeds of 7 mph.

"We're well-pleased with our self-propelled sprayer, especially since the cost was only half the price of a new pull-type sprayer."
