Rashi on Leviticus 22:24/רש"י על ויקרא כ״ב:כ״ד

1ומעוך וכתות ונתוק וכרות are forbidden as sacrifices whether the mutilation be in the testicles or the membrum.

2מעוך means, one whose testicles have been pressed by hand.

3כתות CRUSHED — it implies more severely crushed than מעוך.

4נתוק — they have been torn off by the hand, so that the threads on which they hang have snapped but they are still in the scrotum, the scrotum itself not having been torn off.

5וכרות — they have been cut away by an instrument but are still in the scrotum (cf. Sifra, Emor, Chapter 7 9; Bekhorot 39b).

6[ומעוך — Its translation in the Targum is, ודי מריס; this is its exact translation in Aramaic, because this Aramaic root has the meaning of pounding.

7וכתות, however, is translated by the Targum ודי רסיס “and that which is smashed”, (a stronger term than מרס), similar to, Amos 6:11) “The great house shall be smitten into רסיסים‎” i. e. into small fragments; similar is the Talmudical expression (Shabbat 80b) a reed crushed to pieces (מרוסס‎‎‎‎)].

8ובארצכם לא תעשו NEITHER SHALL YE DO IN YOUR LAND this thing — to castrate any cattle or beast even if it be unclean. That is why Scripture adds “in your land” — to include every animal that is in your land under this law (cf. Chagigah 14b and Tosafot there). For it is impossible to say that they are here commanded to abstain from mutilating animals in the Land of Israel only, (and that the word must be translated: “In your land you must not do this”, implying, but you may do it elsewhere) for surely the command regarding mutilation is a personal duty and any personal duty has to be practiced both in the Land and outside the Land (Kiddushin 36b; cf. Sifra, Emor, Chapter 7 11).
