Who hasn't experienced this yet: In uneven terrain, the boom of the field sprayer will often swing violently up and down during the application of crop protection products and fertilisers.
This leads to uneven distances between boom and ground that result in suboptimal boom heights and affect the precision of the application. If you are looking for a remedy, the Norac UC7 system from Topcon is an effective solution. It can be retrofitted to field sprayers of many brands.
How it works
Retrofitting eliminates the need for constant manual height corrections and significantly increases the speed and impact of the application. Three – or optionally five – ultrasonic sensors on the boom arms ensure that the perfect height is automatically maintained. In addition, integrated gyros inside the ultrasonic sensor detect the rotation angle and speed of the boom. Depending on the system's configuration, a central computer acts as a control module for the possible functions such as raising, lowering, turning or angling the boom wings. Either the height of the crop, the ground level or – in hybrid mode – an average of crop height and ground level can be used as reference point for the measurement of the sensors. The system is either operated via a separate ISOBUS control unit or via a universal terminal on the vehicle.
