Depending on the drive-train system (electric vs. hydraulic, automatic vs. manual, etc.), the electrical system can be a critical component of a tractor. In the past, our team has broken the electrical systems into four major groups: the drive-train circuit, the starter circuit, the safety circuit, and the display. The goal for the electrical section is to have all systems (drive-train control system, battery location, wiring harness, etc.) ready in conjunction with other important systems such as the drive-train, frame, and steering.
Communication is key. Electrical and Mechanical engineers don’t always know what each other is doing. A certain amount of background information may be necessary to understand the other side. In addition, the slightest mistake may cause big problems later–killing the engine for example–and a lot of times when something goes wrong, it is not always easy to diagnose an electrical problem (especially if the system is complex!).
The electrical section works closely with the drive-train, frame, and steering sections in order to achieve their goals.
