Author Description

Excerpt from The Reclamation Era, Vol. 38: January 1952 The workmen constructed a 36-foot spray boom in three sections, so that the two outer sections could pivot. Vertically and horizontally. They then mounted the middle section on the truck's bumper. To make certain that no weeds escaped in spite of the mobility of the side arms of the bumper spray boom, the crew added a hand boom with a hose line 150 feet long for sharp-shooting, or scouting weeds beyond the range of the bumper mounted boom. They constructed special valve controls on the truck cab so the driver could spray from any one, or all sections, at' the same time. But the one unit was not enough to allow the crews to cover all the weeds at the proper stage of growth to prevent their spread and to eliminate the necessity of clearing away dry weeds. So, early in 1951, under the supervision of the project manager and the irrigation supervisor, the shop foreman went to work again, this time making several improvements over the first rig.
