ABSTRACT:
An implement, preferrably a harrow having a row of soil working members mounted on upwardly extending shafts, has spraying nozzles for dispensing material on the ground adjacent the rear of the soil working members. The nozzles communicate with liquid material under pressure. The implement is coupled to a tractor and the operator of the tractor can monitor the material being sprayed by various devices in an electrical circuit that leads to the tractor. Wires are positioned to be bridged by the spray and indicator lights on the tractor dash board provide a visual signal when material is sprayed by each nozzle. Similarly, a micro switch or camera, or other actuation means can be located adjacent each nozzle to provide a signal for each nozzle spray. The nozzles communicate with an elongated pipe and the pipe is supported on the implement frame with adjusting means to change the direction of spray by the nozzles. A supporting roller member is connected at the rear of the frame and the pipe, with nozzles, is positioned between the soil working members and the roller member.
