An Economical, On-Board Digital Monitor for Tractor-Operation Variables
ABSTRACT IN 1975, a portable and interchangeable set of instru-mentation for measuring draft, fuel consumption and wheel speeds was designed and constructed in Missouri. This instrumentation was monitored by a light-beam oscillographic recorder, which was susceptible to damage due to vibration. This is a report on the design and con-struction of a new monitoring instrument capable of withstanding the hazards of in-field use.
