We have always rented pasture by the head. $40.00 for cow-calf. Same for bulls,hiefers or steers. One landlord wanted a check every month so we paid him $7.00 a month per head.
Some pasture is free from absentee land owners, but then we have to do all the fencing. They want to keep the land in agriculture to keep the property taxes down. Good reading is
