The equipment used for the post-harvest treatment and preservation of durable and perishable produce includes cleaners, sorters and graders, fans (for fresh air ventilation and fumigation), dryers, refrigeration, controlled atmosphere equipment, conveyors, and handling, packaging and labeling equipment (see also, Equipment for Post-harvest Preservation and Treatment of Produce).
It is thus no accident that rental markets for threshing machines were well established in the nineteenth century in the United States and are now common all over Asia (Gardezi and others 1979; Walker and Kshirsagar 1981). The contract-hire system for combines in the United States illustrates the problem of synchronized timing. The contractors achieve higher rates of machinery utilization by migrating to follow the harvest from the TexasOklahoma area to the northern states, where harvesting takes place months later.
