How does the responsibilities of a Rancher change during Winter and Summer?

The responsibilities of a rancher on these seasons are following:

Summer: Irrigation chores begin in mid-spring through about August. Ranch hands perform maintenance on ditches and pipes, making any necessary repairs. The workday lengthens from dawn until dusk, seven days a week. In the summer, ranch hands move cattle from pasture to pasture more often, as well, to prevent pastures from becoming overgrazed. The first cut of hay usually happens in June or July, and into August. The ranch hand preps, oils and checks that the haying equipment is in good working order.

Winter: Winter is mostly about maintenance. Ranch hands feed the cattle and livestock every day, since the pastures are usually frozen or blanketed with snow. Firewood collection continues. Maintenance and perimeter fence checks also continue through winter.
