A study of rotary drum mower blade wear and its effects on forage productivity

Egyptian clover (Trifolium alexandrinum) is the main and oldest cultivated winter forage leguminous crop in Egypt. It occupies about one third of area with average 1.63 million Feddan (Feddan= 4200 m2 ). With an estimated productivity 42.03 tons green fodder [7]. In last years, mower conditioner machine used Egypt to cutting crops. The mean objectives current research were evaluated new wear blades attached rotary drum conditioner. As well as, study effect on under local conditions. carried out Sakha Research Station, during session 2016/2017. was operated by tractor cut Berseem crops (Sacha-4) at three different moisture content 65.4%, 57.3 46.2 % (d.b.) second alexandrinum). results indicated that, maximum value 4.96 ton/fed compared 2.42 ton / fed for Alfalfa 56.3 %. This result that old blade or knife may be going reduce as 49.9%. fuel consumption 23.04 l/fad 15.4 l/fed 65.7 consumed low values per L/fed.
