That will ultimately determine how much CFM you'll need to transfer across the pasture and what size lines to bury if you go that route.
I think it is also worth consider running power across the pasture in addition to a 1-1/4" pump line and instead of having your vacuum pump and releaser at the sugarhouse, place a vacuum pump and electric releaser at the woods and pump back to the sugarhouse from there through the buried line. Could use a mechanical releaser and a tank as well and pump from the tank but an electric release is likely cheaper and easier.
