ABSTRACT:
A vision correction device for enabling a tractor to be maintained in centered relation over a guide furrow or the like includes a sighting device and a mounting strip for supporting the sighting device on a tractor forwardly of the operator seat and with freedom of transverse movement relative to the longitudinal center line of the tractor. A lock mechanism is provided for securing the sighting device in a selected transverse position whereby upon adjusting the sighting device to intersect a line of sight from the dominant eye of an operator on the operator seat to a ground furrow situated forwardly and centrally of the tractor, the tractor may be maintained in centered relation over the ground furrow by steering the tractor to maintain the sighting device in alignment with the ground furrow.
