For Techno-farmers

No, this isn't a new "extreme tractor" video game, or a cornfield simulator... not quite, anyway! In fact, this computer and toadstool-shaped receiver are an all-new GPS satellite guidance system for tractors.


Start your engines!

Imagine yourself facing a field stretching as far away as the eye can see. There you are, at the wheel of your tractor, with no reference points, and you have to drive in a straight line as you spread your fertilizer. Not easy!

Now, thanks to GPS technology, a new computer system plots the equivalent of a yellow line down the highway on the farmer's screen.

Keeping to the straight and narrow

At the start of the day, the farmer defines a starting line by driving the tractor along it. For the rest of the time in that field, the computer keeps him parallel to this reference line. It shows the position of the tractor, to within one metre of the line it should be following. He can correct his route almost without having to look out of the cab!


Too much, or not enough?

In farming, precision is essential. Farmers have to make sure they don't spread chemicals twice in the same spot (overdosing), but also be sure that they haven't missed any spots. The GPS location system improves the efficiency of farm machinery by 20% to 30%, with considerable benefits for agriculture and the environment.
