Sprayer Operation On Level Turf - Toro Multi Pro 1750 Service Manual

Sprayer Operation on Level Turf

During sprayer operation with the sonic boom switch in
the automatic position (sonic boom light is illuminated),
the boom mounted sonic boom sensors continually
send impulse signals and then receive echoes as the
signals bounce off the turf. The Toro Electronic Con-
troller (TEC) determines the sensor distance from the
ground based on the elapsed time between the sensor
signal generation and the received echo. As long as the
sensor height remains the same as the calibrated
height, the spray boom will remain at a fixed height from
the ground for spraying accuracy.
On level turf, the boom sensors continually send signals
and receive echoes that determine that the boom sec-
tions are at the calibrated height. Thus, there is no need
to change boom height. The TEC does not energize lift
control manifold solenoid coils so hydraulic flow by-
passes the boom lift cylinders (Fig. 1). The boom sec-
tions will remain at the correct, level position.
