Since 1991, the CALIBRATOR has been the solution for intelligent spreading by using a computer to automatically control application rate relative to forward speed.

BOGBALLE introduced the world’s first fertiliser spreader with an integrated weigh cell (W) for automatic calibration operated from the tractor seat. Since 1994, direct linking to GPS systems has also been possible.


CALIBRATOR is offered in two variants:

The Super Professional CALIBRATOR ZURF

The Professional CALIBRATOR ICON
