Abstract

A drive apparatus has a first and second shaft rotatably mounted on the agricultural fertilizer implement. A drive wheel is fixed to the first shaft and an output wheel fixed to the second shaft. There are a plurality of wheels coupled to the first shaft and a plurality of wheels of varying sized fixed to the second shaft. A flexible connecting means is trained between a pair of selected wheels on the first and second shafts. A drive means rotates the drive wheel. A connecting means couples output wheel to the metering device. An engaging means is coupled to each of the plurality of wheels located on the first shaft coupling the selected wheel on the first shaft with the first shaft so that the wheel will rotate with the first shaft. There is also a control means that allows a user to selectively activate one of the engaging means located on the first shaft. When one of the engaging means is activated, one of the plurality of wheels is coupled to the first shaft and begins to rotate with the first shaft. The corresponding wheel located on the second shaft, coupled to the wheel on the first shaft by the flexible connecting means, begins to rotate the second shaft. The output wheel begins to rotate with the second shaft and transfers power to the metering device which regulates the amount of fertilizer dispersed from the implement.
