Kilayim 5:2 - 5:3

כרם שהוא נטוע על פחות מארבע אמות – that there isn’t between each row four cubits.

אינו כרם – and he distances it six handbreadths and sows the remainder, for since he is not able to plow in the rows between them, the name of “vineyard” is not upon them.

וחכ"א כרם – for he view the middle sections as if they do not exist and combine the outer areas, if there is between them the appropriate space for them,. Because it is the manner of people to plant many consecutive rows together, and those which are appropriate to be sustained and to be made a vineyard will remain a vineyard, and the rest will be for wood, therefore, those that in the middle that are planted within the appropriate space to be between one row and another, we see them as if they are mere wood, and the outer ones combine to be a vineyard.

וזורעים בתוכו – for it is considered an interruption and a different domain since it is deep ten [handbreadths] and wide four [handbreadths] and open, but less than ten [handbreadths deep] or four [handbreadths wide] or even if it is ten [handbreadths] deep and four [handbreadths] wide but it is not open but rather that the vineyard surrounds it from three directions, we don’t seed in it, for it is like a wine-press that Rabbi Eliezer and the Rabbis disagreed on further on , but Rabbi Eliezer ben Yaakov holds like the Rabbis that it is forbidden to sow in a wine-press.

שומרה שבכרם – a high hill that the guard stands upon to guard the vineyard and see from afar.

זורעים בתוכה – but in this, the Rabbis don’t argue on Rabbi Eliezer because it is high and the air space of the vineyard doesn’t surround it but in a wine-press where the air space of the vineyard surrounds it, the Rabbis forbid it, and this is the Halakha.

ואם היה שער כותש – that the tendrils of the vines which are called, “hair,” would be combined and entangled above on the watch tower one on top of the other like the pestle in the mortar.
