Take into consideration headlands, corners and shelter belts etc.,
Both the wrong speed and wrong area indicate that the incorrect settings have been entered in the “configuration settings” of your drill. Check that the correct “drill width” is entered. Check that the correct wheel pulses have been entered for your drill configuration settings.   (See operators manual). Check the TAEGE operators manual for your settings or if unknown.

Eg., below

Drill with 121mm spacings. Is number of tynes * 121 = 23*121= 2783

Drill with 121mm spacings. Is number of tynes * 121 = 29*121= 3509

Drill with 121mm spacings. Is number of tynes * 121 = 49*121= 5929

Drill with 121mm spacings. Is number of tynes * 150 = 23*150= 3450

Drill with 121mm spacings. Is number of tynes * 121 = 29*150= 4350

Drill with 121mm spacings. Is number of tynes * 121 = 19*150= 2850

If fitted to other implements the should be the working width of the machine.
