Bir direk \u00e7ukuru kaz\u0131c\u0131s\u0131n\u0131n mekanik yap\u0131s\u0131 basittir: bir \u015fafta monte edilmi\u015f bir burgu ucu, bir di\u015fli kutusuna ba\u011fl\u0131d\u0131r ve trakt\u00f6r\u00fcn PTO'su taraf\u0131ndan bir tahrik hatt\u0131 arac\u0131l\u0131\u011f\u0131yla tahrik edilir.
