摘要： A connector for connecting earth-treating implements to a tractor includes a slanted inverted U-shaped frame (12) having leading and trailing slanted upright sections (16 and 18) and a relatively level elevated mid-section (19) interconnecting the upright sections, with each of the upright sections having three-point hitches (20 and 22) mounted on the trailing sides thereof. The leading and trailing upright sections each comprise slanted upright posts (16a,16b and 18a,18b) at side edges thereof with horizontal posts (16c,16d and 18c,18d) mounted therebetween and vertically spaced from one another by about 24 inches to provide mounts for vertically spaced three-point hitch mounting members. The mid-section (19) comprises two substantially level beams (56 and 58) extending between upper ends of the upright side posts of the upright sections (16 and 18). L-shaped frames (60 and 62) connected between the trailing upright posts (18a,18b) and the level mid-section beams (56 and 58) form wheel supports and provide a support cradle on which a sprayer tank (72) is carried. Liquid is sprayed from the tank by means of a metering mechanism activated by a cultivator's wheel rotation.
