Abstract

1483581 Agricultural machines A GENT 9 Aug 1974 [11 May 1973] 22465/73 Heading A1B An agricultural machine path indicating device comprises a horizontal support 4 mounted each side of an implement or the rear end of a tractor and supporting a pivoted trailing bar 5 at the lower end of which is a guide or foot 6 which follows a furrow F' previously formed by the machine in the ground. Switches 7 are positioned on either side of the pivot of the bar 5 and these are actuated if the bar 5 is caused, by misdirection of the machine, to stray sufficiently from its central position. Lights or other warning devices mounted on a tractor, which pulls the machine, are connected to the switches 7 and indicate path deviations. In another embodiment the bar 5 is fitted with a cam which is adapted to actuate the switches 7 during rotation, also the switches 7 may be replaced by one two-position switch.
