Rolling Friction is much much less than static or kinetic friction (theoretically 0, if wheels were perfectly round).
If you want to learn about rolling friction, comment.

Yes, in earlier days huge blocks for making pyramid were shifted by logs of wood.
This is done so that to reduce drag, or you can say friction between the block and earth.
Similarly here Mohan's father used the principle of rolling friction to transfer refrigerator.
