Description: Most herdsmen in Eastern Canada conserve forage as hay to meet their live stock needs during the winter. The hay tedder can improve drying conditions by spreading and fluffing the hay swath and consequently reduce drying time and weather damage risk. The present research was initiated to quantify the effect of tedding on the hay drying rate. A hay tedder was evaluated in 1984 over four large timothy plots (37m by 152m) and in 1985over three timothy plots and two alfalfa plots. The forage was mowed at three dates (10June, 25June,9 July) during the first growth cycle to consider the effect of crop maturity. The cut forage was left initially either in a wide swath(1.83maverage) or in a narrow windrow (1.14 m) behind an average mowing width of 2.59 m. The crop was generally tedded in the morning of the second drying day. Under favorable weather, tedding increased the drying rate of narrow (wetter) windrows by 77% and of wide (drier) swaths by 22%, over a 3-hperiod. Over an 8-h period after tedding, drying rate increases were 58 and 28% for narrow and wide swaths, respectively. Under more humid conditions, tedding increased the drying rates by 46% over a 3-hperiod and by 39% over an 8-h period with little difference between wide or narrow windrows. Tedding was more efficient in wet and early-maturity hay. No significant differences were identified between alfalfa and timothy in their drying response to tedding. These results should eventually be integrated in a hay harvest management system to help farmers decide whether tedding is appropriate and when it might be applied profitably.
