Abstract :ABSTRACT : A field test was conducted to compare five different rakes used for alfalfa and grass hay windrowing in order to determine their effective working width, width efficiency and field capacity. Width efficiency and field capacity were substantially higher for the multiple unit rotary tedder and the universal rotary tedder. The values of width efficiency for these rakes were obtained as 99% and 97% respectively. Field capacity was twice as high for the multiple unit rotary tedder as compared to all other rakes used in this study. The values of average effective field capacity obtained in the two plants were found to be as 3.37, 1.79, 1.52, 1.43 ha/h and 1.40 ha/h for multiple unit rotary tedder, universal rotary tedder, finger-wheel side delivery rake, cylindrical-reel side delivery rake and chain-finger side delivery rake, respectively. Key words: Rakes, windrowing, field capacity, effective working width.Keywords : Rakes, windrowing, field capacity, effective working width
