Abstract
Abstract A ground working implement operable to mix liquid or granular materials, as fertilizers, herbicides and like agricultural chemicals, into the surface of the soil. The implement has an inverted, generally U-shaped housing carrying a plurality of spring biased earth working members, as spring teeth. In one form, parallel linkage means pivotally mounts the housing on a support. Wheel structure connected with arms to the housing is used to adjust the earth working depth of the teeth. In another form, an upright standard and clamp adjustably mounts the housing on a tool bar to adjust the earth working depth of the teeth. The material is discharged through a nozzle mounted on the front of the housing whereby the implement, as it moves in a forward direction, discharges the material onto the soil. The material is worked into the soil with the teeth.

158 words
An apparatus for incorporating material into the soil comprising an inverted, generally U-shaped housing having a generally horizontal top wall, downwardly directed side walls connected to the top wall, an open front end, an open rear end, and an open bottom; a plurality of downwardly directed earth working members located between said side walls, said members comprising generally upright fingers having lower ends adapted to work the surface of the soil adjacent the open bottom of the housing; means mounting the fingers on the housing with a portion of each finger engaging the top wall; means centrally mounted on said housing for directing material onto the soil adjacent the open front end of the housing; linkage means connected to the housing adapted to connect the housing to a support whereby the housing can move toward and away from the soil; and wheel mean connected to the housing engageable with the soil to support the housing above the soil.
Claim 2
Independent Claim
158 words
An apparatus for incorporating material into the soil comprising an inverted, generally U-shaped housing having a generally horizontal top wall, downwardly directed side walls connected to the top wall, an open front end, an open rear end, and an open bottom; a plurality of downwardly directed earth working members located between said side walls, said members comprising generally upright fingers having lower ends adapted to work the surface of the soil adjacent the open bottom of the housing; means mounting the fingers on the housing with a portion of each finger engaging the top wall; means centrally mounted on said housing for directing material onto the soil adjacent the open front end of the housing; linkage means connected to the housing adapted to connect the housing to a support whereby the housing can move toward and away from the soil; and wheel mean connected to the housing engageable with the soil to support the housing above the soil.
Claim 3
Dependent Claim
47 words
