Sometimes I get lucky and can make dry oat hay. But more often than not I end up wrapping them because the weather and the oats aren't in sync as far as dough stage and warm dry weather at the same time.
If you don’t cut it it won’t dry. Ha ha. I would make the windrows as wide as possible and hope for a long window of dry weather. Usually we turn it over to dry on the other side before we take it together unless there is too much to take double, then just singe again.
