It's hard, heavy, hot work. Lift the bale, toss onto the trailer. I usually use a crew of 4 to do this; a driver, myself, and two big burly guys. We take turns being the bale tossers and the bale stackers. I pay those guys $15/hour and they earn it. It ends up costing me $0.55/bale to have it picked up in the field and then stacked in my hay barn, which isn't bad.
This years hay is much better quality - the farmer I buy it from is a relatively new farmer, and he's been working hard at producing better forage. This years is cut about perfect; just as the seed heads appeared, and is green and smells great. The hot weather has dried it out perfectly.
When you're loading or unloading bales there's always some that bust; the pigs and cows and sheep all approve of this new hay.
So if you're interested in good quality local hay, I'd recommend Won, at 206-229-0191. His farm is located 2 miles south east of downtown Everett, and he's got 2,000 bales to sell.
