Moving muktza indirectly is allowed in the following case: A radish has been put under some earth for cool storage. Its leaves are sticking out. You are allowed to pull up the muttar radish by its leaves because you want the radish, even though the muktza earth is moving indirectly. This is called tiltul min hatzad l’torech dovar hamuttar. (ShA 8)
Nevertheless, the din changes to be ossur in one of the following variations:
You intended to plant the radish – harvesting.
The radish took root – harvesting.
A hole will be left in the dirt floor of a building – you might come to fill it up which is Boneh.
The radish is completely covered – you will need to move the muktza earth directly.
Your intention is to have the earth moved around – indirect tiltul is not allowed for the purpose of the muktza. (MB 25, 26, 27, 28)
There is another type of indirect tiltul that is permitted even for the purpose of moving around the muktza. It is called tiltul b’gufo – moving the muktza with your body or your other limbs (not with your hands) (ShA 8 – MB 30)
Some people justify selling their merchandise on Shabbos by receiving the money in a special cup so they aren’t moving the muktza directly. It emerges from what he have learned that this is absolutely ossur – besides for the great evil of business on Shabbos. (MB 38)
