What is an example of the excessive taxing, or overtaxing, of serfs under feudalism?

Question

Serfs were only given a few pieces of equipment.

Serfs had to rent land on the manor.

Serfs had to pay to have the grain they grew milled at the manor mill.

Serfs collected taxes from the knights, but had to turn the money over to the lords.

Answer 1

From Internet:

The serfs had to pay “in kind” (grain sacks, wine barrels, oil jars, livestock) the right to live on those lands, and the vassals, in turn, had to pay large rents, also generally in kind. These incomes can be considered taxes. Another kind of tribute was the tithe, originally a contribution to guarantee the maintenance of the clergy.
