The performance test of New Holland Crop Dryer (type 751) was carried out on the baled-hay and the following results were obtained. 1) The static pressure decreased 2 to 5 mmAq and the air fiow increased about 50m^3/min at the last period of drying compared with the first period. 2) The temperature of heated air at the duct was 32〜35℃ when the fuel consumption was abut 30l/h and themperature of out-side air was about 10℃. 3) The curing speed was rapid during 2 or 3 hours at first and then it became slowly. 4) The fuel consumption for drying hay varied over a wide range according to the moisture content of the partially dried hay. The fuel consumption to dry the hay of moisture content below 30% was 76〜78l/ton, however to dry the hay of moisture content exceeding 50% the fuel consumed 157l/ton. To dry the baled hay uniformly and low cost, it should not be placed in the drying barn with an average moisture content exceeding 40%.
