ABSTRACT:
A material-spreading field vehicle has a large hopper for holding comminuted plant nutrients, a conveyor for feeding nutrients to an evenly spreading distributor, and a plurality of relatively small always-carried auxiliary containers for holding concentrated water-solutions and/or suspensions of herbicides, insecticides, hormones and other soil-treating chemicals. The apparatus includes vehicle-speed-responsive mechanism for insuring uniform mixture of the solid and liquid materials prior to spreading, by the use of positive-action pumps for each liquid feed line to insure accurate metering of each liquid to the conveyor which leads to a conventional mixer upstream from the distributor. Each pump is driven from the vehicle-speed-responsive mechanism by a variable-ratio speed-changer for metering the several materials being combined. A manually controllable device may be employed to vary the mixed-material-dispensing rate as desired.
