No idea where you got that impression, but farming is constant chores. And moreover this 19th century farming. So a typical day looks like this:
get up at ass crack of dawn
clean out remains of yesterday's fire from the stove
empty piss-pot
collect firewood for kitchen stove and get the stove going for the day
fetch water from well, hauling it by the bucket full to the cistern for the house
by now other people in the house are waking up and will be wanting breakfast soon
gather fresh eggs from hen house
milk cows
go prepare breakfast for household
clean up after meal, washing everything
make the rounds cleaning up after the animals and giving them fresh feed and water
if you got horses this is gonna be a long, dirty job
check enclosures to make sure the fences and gates are in good repair
check fields for signs of pests, rot, and weeds
water the garden plots and also check them for the same
break for lunch
go chop firewood to add to the stockpile for tomorrow
second round of checking on animals
miscellaneous household chore time (pick one or more!): mending clothing, washing laundry, making butter, sweeping out house / barn, cleaning fireplace before evening, checking the septic pit (worst chore), and preparing meat and preserves for storage, among others
time to prepare dinner for everyone
sunset so get the fireplace going so people have a nice warm room to gather in once it's dark
wash up for the evening
turn in
These are just the daily chores you'd probably do, not accounting for actual farming responsibilities like detailed animal care, plowing, tilling, sowing, reaping, etc, or occasional errands that take you into town and eat up most of the day.
Sure you have slow days where there's not much to be done, but there's always SOMETHING that needs to be done. It just doesn't have to be you who does it, if you've got lots of hands around to do the work.
