Machshirin 3:8-4:1

Machshirin 3:8

If one lowered the wheels of his wagon or the gear of his cattle into water at the time of the east wind in order to tighten them, ki yutan applies. If one took an animal to drink, ki yutan applies to the water that comes up with its mouth but not to the water that comes up with its feet. If he intended to wash its feet then ki yutan also applies to the water that comes up with its feet. When an animal has sore feet and when it threshes, ki yutan always applies to the water that comes up with its feet. If a person with congenital deafness, a person lacking mental faculties or a minor took the animal down to the water, then even if his intention is that the animal’s feet should be washed, ki yutan doesn’t apply because their actions are effective but not their intentions.

Machshirin 4:1

If one bent down to drink, ki yutan applies to the water that comes up with his mouth and his mustache but not to the water that comes up with his nose, head or beard. If one fills a jar with water (i.e., by lowering it into the water) ki yutan applies to the water that comes up with it, on the rope tied around its neck and the rope used to pull it from the well. Rabbi Shimon ben Rabbi Elazar says one handbreadth (about 3”) of rope is needed for the latter purpose. If one placed the jar under a rain pipe, ki yutan doesn’t apply to the jar’s exterior or to the rope.
