In planning for farm machinery needs, a knowledge of the field work time available, both for spring planting and fall harvesting, is an important factor. This paper is concerned with the effect of weather on field work in fall. There are several factors which determine the time available for harvesting specific crops but this study only deals with tractability. A simple model is described which estimates field work conditions on a day-to-day basis and which can be applied to historical weather records to analyze long-term risks. A day is assumed suitable for field work when the soil is tractable. If excessive wheel slippage can reduce a tractor
