GPS, field mapping, automated steering, and tracking telemetry are all technologies reducing waste (overlap) and increasing productivity. Without these modern gizmos, overlap can be 20% or more. With the aid of computers, overlap waste can be reduced to just a percent or two. The savings in time, fuel, wear and tear is proving these technologies well worth their added cost. Imagine yourself running a 33’-wide hay cutter while the onboard electronics pick the engine rpm, choose the path and communicate with the automated steering—while you follow market prices on a laptop in air conditioned and filtered comfort. Well, that time is today.
