What [constitutes] a field of trees? Any three trees to a beis seah. If they are capable of yielding a block of pressed figs [with the weight] of sixty Italian maneh, one may plow the entire beis seah on their account; [if they yield] less than this, one may not plow for them more than the [area] occupied by the gatherer and his basket, outside it.

Until when may one plow in a field of trees on the eve of the seventh [year]? Beis Shammai say: As long as it is good for the fruit. But Beis Hillel say: Until [the festival of] Shavuos. The opinion of these is close to being like the opinion of these.
