They say that everything that is old becomes new again, and the implementation of instructions is no exception. Technology that has been available to farmers since the 1970s is increasingly becoming mainstream as farmers seek to be more efficient and economical with machine-to-machine.
Guiding attachments to targeted paths provides the most accurate attachment control. The implementation guide can be divided into two categories:
Passive leadership. These systems combine GPS data from mounted receivers on both the tractor and the attachment to automatically steer the tractor so that the attachment always remains on the intended guide path. This is the more economical entry point, but the downside is that the tractor can move on and off the track to keep the implement on the intended path.
It is best for gradual and systematic drift, so it is combined with a sturdy seed bar to minimize transient and sudden accidental drift.
Active guidance. These systems guide the implement independently of the tractor. Active implement guidance is more expensive, but the extra accuracy can be provided to improve crop yields. This technology is based on special automatic steering systems for the attachment, of which there are two main types:
A) The clutch correction adjusts the drawbar of the tractor or the drawbar of the attachment hydraulically to the side in order to guide the implement. A system controller responds to position data from the GPS receiver from the implement itself or to data from a stubble row or furrow / ridge tracking sensor attached to the implement. This approach adjusts the attachment position up to a maximum offset, but without …
