The aim of this study is to develop a John Deere Pickup Baler for chopping and compressing rice straw and stalks of wheat  for Processing non-conventional Forages .This study was conducted by using a develop John Deere Pickup Baler to show the effect of straw moisture content and stalks of wheat are (36.0, 30.0,24.0 and 16.0 %), (28.0,25.0,22.0 and 18.0%) respectively ,machine forward speed (1.8,2.3,3.5 and 4.4 km/h) and different knives speed (18.0, 20.0, 23.0, and 26.0 m/s) on lengths of cut, Efficiency of straw bales, effective field capacity, energy requirements and unit cost .The results indicated that increase the forward speed from (1.8 to 4.4 km/h) at knives speed 26.0 m/se and straw rice moisture content of 30%, stalks of wheat.25.0%, w.b  respectively tends to decrease lengths of cut of straw rice from (63.0 to 32.0 mm) and ( 60.0 to 28.0 mm) from stalks of wheat ,increasing effective field capacity from (0.61 to 1.14 and 0.655 to 1.4 fed/h.) respectively , decreasing energy required from (60.65 to 32.457 and 56.92 to 26.42 Kw.h/fed respectively)  and decreasing unit cost from (87.06 to 46.58 and 81.7 to 37.93 LE/fed.), respectively. Also, straw moisture content of 36.0 % and stalks of wheat 28.0 %w.b. gave the highest values of chopping length, Efficiency of straw bales, energy requirements and unit cost  at forward speed 1.8 km/h and knives speed 18 m/se
