Lots of luck. If you are new to baling (note the spelling) hay, you won't have any of the east jobs. In preparation, the grass (or legume) is cut and left in the field to dry. After a day, it is tedded, tossed in the air to help in drying, Then it is raked into windrows with a side-delivery rake. Finally it is picked up with a baler, compressed, chopped and bound with wire or twine. This is where you come in. If you are lucky, you will have leather-palm gloves and hay hooks. If not, you will have torn-up hands. You will either walk behind the baler and toss the bales up onto a wagon (driven by someone who ranks higher than you do) or you will be on the wagon and have to toss the bales up onto a pile. If you are really unlucky, you will be doing both those jobs.
You think that is bad? Try bringing in the hay loose. Much worse.
