1. A transmission system, comprising:
a first gear ratio coupling a forward clutch and a first shaft to an intermediate shaft;
a second gear ratio coupling a reverse clutch and the first shaft to the intermediate shaft;
a third gear ratio coupling the intermediate shaft to an output shaft, the output shaft extending from the transmission system; and
an output of a mover, the output surrounding the first shaft, wherein the forward clutch locks the first shaft to a first gear of the first gear ratio and the reverse clutch locks the first shaft to a second gear of the second gear ratio,
wherein the second gear ratio includes an idler shaft which couples the reverse clutch to the intermediate shaft, wherein the first shaft is a forward reverse shaft and the forward clutch and the reverse clutch surround the first shaft, and wherein the first shaft supports the forward clutch and the reverse clutch via bearings.
