56 not illustrated to prevent downward movement of the seat 110 on the pipe 56 the swivels 120 and 122 will allow the seat 110 to rotate 360 u00b0 around the pipe 56 extending downwardly from the nozzle water pipe 104 is a directional control arm 124 as can be seen in fig1 and 2 a workman climbs up the water tower to the seat 110 by means of plurality of vertically spaced apart steps 126 which are welded or otherwise secured to water pipe 46 because of the preferred length of the water pipe 46 the worker is elevated high enough in the grove of trees whereby he can direct the flow of water by means of direction control arm 124 in view of the fact that the water pressure is usually quite strong when attending to almond trees as previsouly discussed the spray is not aimed at the row of trees directly adjacent the sprayer 12 but to trees in the next row see fig1 with the worker 39 s vantage point from the seat 110 he may than direct the spray when he desires to move the spray 180 u00b0 from the position shown in fig1 and 2 he merely pushes against the nearest step 126 rotating the chair and himself around the vertical axis of the tower 124 and the water nozzle pipe 104 and water pipe 108 will rotate by means of the rotatable water nozzle mount 60.
