פירוש על בבא בתרא 55:2

Field of the house owner - Nourished from rain water, it doesn't make fruits except one time in a year, his chazaka is 3 years and (it does) not need to be from day to day. And what is its Chazaka? Rabbi Ishmael says last three months of the first year and three first months of the last year and a complete middle (year), that (because) there is the hurry to plant before the the new year, and since the chazaka comes (at)three months at the end of the first year and he has witnesses that he planted in those three months and also in the first three months of the last (year), behold this is chazaka of three continious years, that (because) there isn't for you, a man who sees that his friend plants his field (so as) to eat the fruit made (grown) for the year and stays quiet.
