ABSTRACT Afield study was conducted to measure the effect of machinery sequences on the drying rate and material loss when harvesting alfalfa hay. Twenty-four combina-tions of four mowing, three late conditioning, and two raking treatments were evaluated under the relatively humid conditions of the Upper Peninsula of Michigan. A cutterbar mower with a roll conditioner and a rotary mower with a flail conditioner provided faster drying than the rotary or cutterbar mowers alone. Late condi-tioning with a crimper was effective in speeding drying, but losses were greater. Tedding had little effect on dry-ing and both raking treatments provided similar effects on drying.
