This is one of the products that I sell it not only steers the vehicle but records and varies the rate of fertilizer or chemical put on the crop. This makes it more efficiently and doing it automatically reduces fatigue of the operator. This product can also be installed in a harvester to record the yields so you can maximise the potential of the soil each season. The demand has been awesome and my part time job is turning into full time one but that is alright I guess. So next time you see incredibly straight crops you'll know a bit more about how they got that way.
