Abstract :The current study was conducted at the experimental field, College of Agriculture, University of Salahaddin in Erbil at Gerdarasha. Corn was selected as a sensitive plant to soil compaction that was grown on a silty clay loam soil texture during the summer and autumn. In this study a new design of tine was provided, then machinery indicators and crop indices were evaluated and compared to conventional one manufactured in Massey Ferguson Corporation. A factorial experiment was conducted by using completely randomized block design with split plot and three replications and Duncan test were used to compare the means of treatment at 5%. The first factor was subsoil tillage depth at three deepness of insert ignore into journalissuearticles values(20 – 25);, insert ignore into journalissuearticles values(30 – 35);, and insert ignore into journalissuearticles values(40 – 45); cm. The second factor included type of tine insert ignore into journalissuearticles values(conventional and modified with wings);. The summarized important points were: Draft force, effective field capacity and, soil volume disturbance, they increased by depth increment. Furthermore, using modified tine type illustrated greater records in contrast to conventional one. Moreover, field efficiency was considerably affected by tine type. Better results were considered by applying modified tine type. Meanwhile slippage percentage was only affected by tillage depth that increased by depth increment. Briefly, by comparison between two tine types, it was observed that all plant indicators showed greater values by equipping the subsoiler with modified tine, although, this superiority was not significant in some indices.
