7.15 WINDROW TYPES
There are three basic criteria by which the quality
of a windrow is measured:
• Weight Distribution - heads and stalks
distributed evenly across full width of
windrow.
• Good Curing - a loose, open windrow for
better drying.
• Good Weatherability - a well-formed windrow
that supports heads off the ground and holds
together in extreme weather conditions.
