The drive-train is one of the most important components of a tractor (or any vehicle really). Without a drive-train, our tractor would be nothing more than a rolling chassis. The goal for the drive-train section is to have a fully functional (can drive and pull) tractor by competition.
The drive-train systems may be one of the more challenging of systems to understand.
The drive-train section works closely with the frame, steering, and electrical sections in order to achieve their goals.
