Explanation #1 (Version #1 of R. Chananel, and Rashi): The document does not mention when the (10) years begin or end. The document is in the renter's hand, and the owner tells the renter "you already lived there five years";

We ask that regarding a loan document, would he be believed to say that he paid half?!

We answer that he says as follows. I wrote to you a document in order that you will not make a Chazakah. I.e. the document was written primarily for me, so you cannot say "I bought it";

The document is in your hand only lest I contradict the calculation of how many years there were. In any case, the document was written primarily for me. Through this, there is publicity that it is a Mashkanta with you, even though the document is in your hand.

Explanation #2 (R. Chananel, Version #2): The document says "at such time I rented Ploni's Chatzer for 10 years for 100 Dinarim, 10 years for each year";

After five years, the renter claims and tells the owner "you took rental for five years..."

We conclude that the renter is believed, through a Shevu'ah. Presumably, this latter version is correct. These are R. Chananel's words.

Support #1: This version is primary. Firstly, also above we discuss the credibility of the renter to say that he paid the rental. It connotes that also this discusses the same matter.

Support: #2: Now it is better what it says in the conclusion that the document was not made for collection, only so the renter will not make a Chazakah. This is why the owner has the document!

Explanation (Aruch, Erech Sho'el): B'Tuvo means for gratitude that the borrower has for the lender, the borrower can use the lender's Kli forever.

Rejection: This is unreasonable.

Question: In Bava Basra (61b) it says that "Ar'asa (lands)" connotes two!

Suggestion: Also there, if he said "Ar'ai (my lands)", it would connote all of them, like Pardesai!

Rejection: It says there that if he said Diklai (my date trees), he gives to him two date trees, and nothing else!

Answer #1: This is only regarding a sale, for we should not say that he sold all his land, rather, the smallest [amount];

However, regarding She'elah, one is not concerned, for one lends for all [the borrower's] needs.

Answer #2: There, the buyer has the lower hand, for the seller is Muchzak. Here, the lender has the lower hand, for the borrower is Muchzak.

Question: The borrower is not called Muchzak, since in the end it will return, and it will not stay with him, like it says above "land stands in the Chazakah of its owner", and even at the end of the month!

Answer: There is different. Only land, which one cannot hide to evade it from its owner, we follow the first Chazakah;

However, for Metaltelim, we follow who holds them now, when there is no Chazakah of land against it.

Explanation: What is cut off with the sheave is called Teven, and what remains in the ground is called Kash [in Leshon ha'Kodesh], which we call stubble;

It says "Gam Teven Gam Mispo Rav Imanu." What remains in the ground is not given to animals to eat;

Also, it says "Lekoshesh Kash l'Teven." They used to gather Kash that remains in the ground in place of Teven, for the owners already took the Teven to their houses.

Support: It says in Shabbos (150b) "granted, we find attached Kash. However, how do we find attached Teven?!"

Implied question: Why does it say in the Gemara "[you may not uproot the sheaves, for] I want that my land Titaven (will have Teven)"? It should say "Titkash" (will have Kash)!

Answer: Because it is common to make a wasteheap of Teven to fertilize the field, it says Titaven, i.e. the Kash will be in place of fertilizer that they make from Teven.

Implied question: Why does it say also "[you may not cut the sheaves, for] I want Teven"?

Answer: There, since he uproots the entire [sheave], and threshes everything with threshing tools, and it gets soft, everything (except for the grain) is called Teven.

Question: Here it connotes that the owner receives less than the sharecropper;

Everywhere, it connotes that the sharecropper receives less, like it says in Gitin (74b) "everyone (other sharecroppers) irrigate three times and receive a quarter. You will irrigate four times, and receive a third";

Also below (110a), regarding the sharecropper says "I entered [worked the field] on condition to receive half", and the owner says "I hired you to receive a third", it connotes that sharecroppers used to get less [than the owner], and not more!

Answer: Here we discuss when the sharecropper gives the seed. Everywhere, the owner gives the seed, or we discuss vineyards and orchards, which do not require seed.

There are places where they do so, that the sharecropper gives the seed, and there are places where the owner gives the seed, like it says above (74b).

Explanation #1 (R. Chananel): This is a ditch and a small ditch. It is common to make them around a field outside the fence, like we say in Bava Basra (108a).

Explanation #2: The Aruch (Erech Arkavta) explained like Rashi (it is earth piled up on the border of the field).

Explanation: This is Shemirah, like "Piv Balum" (Bechoros 40b), i.e. closed, and similarly, one who is Bolem (refrains) himself at the time of a quarrel (Chulin 89a).

Distinction: However, "Otzar Balus" (Gitin 67a) is with a Samech, like "Isah Belusah", which means mixed, in Shabbos (76b) and "Otzeros Belusin" in Bereishis Rabah (9).

Explanation: This discusses Chakirus (renting a field on condition to pay a fixed amount) or Kablanus (working the field for a fixed share of the Peros), like it says in the Gemara.

Implied question: Below (105b), a Mishnah teaches that one was Mekabel a field from his friend, and locusts consumed it, if the entire region was stricken, he deducts from his Chakirus;

It discusses only Chakirus, for regarding Kablanus, he does not deduct. Rather, he receives a third or a quarter, like he stipulated, like Rashi explained below!

Answer: Even so, here in the Seifa he deducts, since he said "Beis ha'Shelachin." There was no need for him to say so, since he was standing in it, since it says "this", like it says in the Gemara!

Inference: [He said Beis ha'Shelachin] to teach "as long as it is a Beis ha'Shelachin."
