Kesici kafa s\u0131k\u0131\u015ft\u0131\u011f\u0131nda, operat\u00f6r t\u0131kan\u0131kl\u0131\u011f\u0131 gidermek i\u00e7in geri y\u00f6nde hareket ettirmelidir. Geri tork, normal ileri d\u00f6n\u00fc\u015f s\u0131ras\u0131nda daha az temas nedeniyle daha az yorulma direncine sahip olan kar\u015f\u0131 (tahrik etmeyen) di\u015f yan y\u00fczeyine y\u00fck bindirir.

Sorun, geri torkun genellikle tam sistem bas\u0131nc\u0131nda uygulanmas\u0131 (operat\u00f6r s\u0131k\u0131\u015fmay\u0131 gidermek i\u00e7in hidrolik tahliye valfini maksimuma iter) nedeniyle daha da karma\u015f\u0131k hale gelir; bu da normal ileri kesme maksimumunu 10 ila 30% a\u015fan tork zirveleri olu\u015fturur. Daha az sertle\u015fmi\u015f temas y\u00fczeyi ve normalden daha y\u00fcksek torkun bu kombinasyonu, ters yan y\u00fczey ar\u0131zas\u0131n\u0131 karma y\u00fczeyli TBM t\u00fcnelcili\u011finde en yayg\u0131n di\u015fli hasar modu haline getirir.<\/p>\n
