Soil cultivating implements
First Claim
1. An agricultural implement comprising an elongated frame and a plurality of soil-working members mounted on said frame in a row that extends transverse to the direction of travel, said members having tines and being rotatable about upwardly extending axes defined by corresponding shafts depending from said frame, driving means connected to rotate said members and said tines to work the soil during operation, a rotatable supporting member being connected to the frame and located to the rear of said soil-working members, said supporting member being a roller that is rotatable about a substantially horizontal axis and spraying means being located between said soil-working members and said roller, said spraying means comprising nozzles in communication with a source of fluid material to be sprayed, said nozzles being mounted on support means and positioned adjacent the soil-working members at the rear thereof, whereby material is sprayed in the immediate proximity of the soil-working members during operation.

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.
