1. A crop row deviation sensing device for agricultural equipment comprising:
- sensor means comprising at least one infra-red transmitter and receiver sensor pair located on the agricultural equipment so as to travel with the agricultural equipment between a pair of adjacent crop rows for sensing crop row deviation with respect to the agricultural equipment;
control circuit means operably connected to said sensor means; and
actuator means located on the agricultural equipment and connected to said control circuit means for effecting movement of the agricultural equipment relative to the pair of adjacent crop rows when said sensor means detects that a preset allowable deviation of location of the agricultural equipment relative to the pair of adjacent crop rows has been exceeded so that deviation of location of the agricultural equipment relative to the pair of adjacent crop rows becomes less than said preset allowable deviation.

Abstract
A device for keeping row crop spraying booms, cultivating tools and other agricultural equipment in the correct position relative to rows of plants, where infra-red beams are used to determine the position of the booms or tools in relation to the rows, and activates rams or other actuators to move the booms or tools to the desired relationship with the rows when preset allowable deviation is exceeded.

2. A crop row deviation sensing device for agricultural equipment comprising:
-
sensor means comprising at least one infra-red transmitter and receiver sensor pair located on the agricultural equipment to travel with the agricultural equipment above a crop row; control circuit means operably connected to said sensor means; and actuator means located on the agricultural equipment and connected to said control circuit means for effecting movement of the agricultural equipment so as to restore the agricultural equipment above the crop row within a preset allowable deviation with respect thereto when said sensor pair detects that the preset allowable deviation has been exceeded.
