(R. Ba bar Chiya citing R. Yochanan): It is forbidden to move Tarchus (a great chair) [on Shabbos. Since it is heavy, people fix a place for it.]

R. Ami ruled that it is permitted.

R. Yirmeyah saw people moving it in the great Beis Midrash. He did not protest (perhaps the Halachah follows R. Ami).

(People of R. Yanai's academy): If it has up to three [steps], it is considered a chair. More than this, it is considered a ladder. (We will discuss the relevance of this.)

(R. Yosah bei R. Bun): The one who permits [Tarchus] holds like R. Shimon;

(Tosefta): One may not drag [on the ground] a bed, chair, bench or special chair [for women to ride on], because he makes a furrow. R. Shimon permits.

(R. Ba citing R. Chunah, R. Chagai citing R. Ze'ira and R. Yosi citing R. Ila): Chachamim agree to R. Shimon about a chair whose legs are sunk in mud, that one may move it.

Just like one may move it, one may return it.

Support #1 (for R. Ila - R. Yosi - Mishnah): [A radish or turnip buried under a vine, if some of the leaves are exposed,] one may take it on Shabbos. (Likewise, one may move a chair whose legs are sunk in mud.)

Rebuttal (R. Yosi bei R. Bun): [The Mishnah] is like R. Shimon [but Chachamim, who forbid Davar she'Eino Miskaven, forbid.]

Support #2 (R. Yosi - Mishnah): All Kelim may not be dragged [on the ground], except for a wagon, for it compresses [the earth underneath, but does not make a furrow. This is like R. Yehudah, who forbids Davar she'Eino Miskaven, and he permits even though he moves earth!]

(Rav Huna citing Rebbi): It was said [that up to three steps, it is considered a chair, and past this it is a ladder] regarding [moving it on] Shabbos.

(Chizkiyah citing d'Veis R. Yanai): It was said regarding Chazakos (one who puts a big ladder in his neighbor's Chatzer in order to get to his roof, if the neighbor did not protest initially, afterwards he cannot protest).

(R. Yosah citing d'Veis R. Yanai): It was said regarding Tum'ah (Tum'as Midras applies to a chair, but not to a ladder).

(Rav Acha bar Chinena citing R. Yosa citing R. Yochanan): One may move a small candelabra.

Question: (What is the Chidush?) Is it not a Kli? Is not everything in the house Muchan? (Rather, we must say that it was burning at the start of Shabbos, and R. Yochanan holds like R. Shimon. However, above he ruled like R. Yehudah!)

Answer (R. Yosi bei R. Bun): The case is, he took it with him to sell, or it came [to his house] just before Shabbos. [He did not intend to use it, so it is a Chidush that it is permitted tven though it was burning on Shabbos,] and you cannot learn from this anything [about whether R. Yochanan holds like R. Shimon].

(Mishnah): [On Shabbos] one may put a Kli under a Ner to catch sparks. One may not put water in it, for this extinguishes.

(Gemara) Question: Here you say that one may put a Kli under a Ner to catch sparks, and one may not put water in it, for this extinguishes, and here (Mishnah 6) you say that one may not put a Kli under a Ner [on Shabbos, to catch oil]!

Answer: Here, he needs the oil (so the Kli becomes a Bosis for it, and he is Mevatel it from its Hachanah, which is forbidden). Here, he does not need the sparks.

(Mishnah): One may not put water in it, for this extinguishes.

(R. Shmuel citing R. Ze'ira): This is like R. Yosi [who forbids putting new Klei Cheres full of water around a fire, for they will break, and he causes the fire to extinguish].

(R. Yosi): We wanted to say that R. Yosi and Rabanan argue about when one made a wall of Kelim [full of water around a fire], but a wall of water (e.g. snow or hail), no (all forbid).

Retraction: However, since R. Shmuel said in the name of R. Ze'ira that [our Mishnah] is R. Yosi, this teaches that they argue even about one who made a wall of water.
