Sprayer Operation On Level Turf - Toro Multi Pro 1200 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 controller
(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.

NOTE: During normal Ultra Sonic Boom system opera-
tion, there may be some slight movement of the booms.
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 and the boom sections will re-
main at the correct, level position.
