If you're on console, loose grass/hay is the only way. The bale limit makes using bales for a medium/large scale operation impossible. Use the placeable hay lofts to store your hay. Mow, ted, windrow and then collect the windrows with a loading wagon.
Mower on the front of a tractor & windrower on the back. Hired help will leave you a nice high line of grass to pick up with a loading wagon or baler.
I use the MF forage harvester (very cheap daily cost), 3ft mower & a 3 point trailer (via big bud pack) to pull the windrower.
^^Dang, thats how I can hire a worker with a baler, hmmmmmmmmmm
