If your intent is to find an easy way to remove "sections" (not necessarily layers) of hay from the bale, a chain saw might work. Sit the bale on end & just cut out what you need, as you need it - might be a bit dusty & need to be careful about fires. Crazy huh? I'm having one of those days.

“The problems we face today are there because the people who work for a living are outnumbered by those who vote for a living."
