Wow! How many head of cattle are you feeding several tons of hay a day to? And my hubby complains because I feed our horses (3 of them) about 40 pounds of hay a day! I am using small bales right now, but usually I have a 6-string bale that weighs about a ton that I feed them off of. I guess forking the hay and sweeping/shoveling the barn daily is a good upper body workout for me!
