Women and children very much participate in farming back then, harvest was a “all hands on deck” situation.
Similarly by adding ‘and clothe bodies’ that captures well over half of a typical woman’s labor back then. Drop spindles sucked up an enormous amount of labor before you even had cloth.
At times it was all hands on deck for harvest - but most of the time it wasn't and that rest is an important part of village life missing. As you say, drop spindles suck.
Bret Deveraux linked to estimates that 70% of producing clothes is spinning, 20% is weaving, and 10% is sewing.
We tend to think of weaving as the time consuming thing but that’s because the spinning wheel had been around for a while by the time the Industrial Revolution happened.
