Three trees belonging to three people combine and they may plow the entire beis seah on their account. How much [space] must there be between them? Rabban Gamliel says: Enough for [a team of] cattle to pass through with its implements.

[If] ten saplings are distributed within a beis seah, one may plow the entire beis seah on their account until Rosh Hashanah. [If] they formed a wall or were surrounded by a fence, one may not plow for them any more than their need.
