A perforated pot condemns in a vineyard, but an unperforated pot does not condemn. R’ Shimon says: This and that forbid, but do not condemn. [If] someone transports a perforated pot through a vineyard, if it increases by a two hundredth part, it is forbidden.

[If] the wind blew vines over grain, he must cut [them] at once; if some accident befalls him, it is permitted. [If] his grain leans under a vine, and likewise with greens, he returns it and it does not condemn. From when is grain condemned? From when it takes root. And grapes? From when they reach the size of a hyacinth bean. Grain which has dried to its full extent, and grapes which have ripened to their fullest, do not become condemned.
