the performance of cotton baling press used (bale press type HUTA KROL model NP. 30) in Egyptian scutchers was evaluated. This bale press was determine the influence of bale weight (kg), bale volume (m³), bale density (kg/m³), bale press capacity (bale/h), power requirement (kw), total bale press cost requirement were investigated. Also, all of staple length 2.5%(mm), staple length 50%(mm), strength(g/tex), elongation (%), lint grade(degree) and trash content (%) were evaluated and tested at four levels of lint moisture content of 11.2, 9.8, 8.7 and 7.3% d.b, three levels of tramper strikes of 7, 10 and 14 stroke/bale and four levels of piston compressor of 1422, 1765, 2206 and 2600 N/cm². The obtained results show that, the highest value of bale weight and bale volume were 400 kg and 0.757m³, the highest value of bale density was 552.5 kg/m³ and the maximum value of productivity was 1400kg/h. also, minimum value of power required was 11.9kw and minimum value of total bale press cost requirement was 141L.E/h. On other hand, results found that studying the characteristics of lint cotton quality at bale press was clear that all the qualities were good to production bales of cotton press when moisture content was less than 11.2% d.b, and more than 7.3% d.b.
