When I drive past farms, I notice large rolls of hay/grass...why roll grass/hay & how is it done?
Question:
Answers:
ok, i live on a farm, and as my summer job i "hay" for about half a dozen different farmers. ok, you take a Swather (its a piece of equipment that cuts the fields, and puts it into "windrows" (which is just all the grass put together in a row" then, you wait untill its dry (it somtimes needs turned by a commercial rake first) then you bring a Bailer (its generally attatched to a tracter and it is usually driven by the tracters PTO) and depending on whether its a round baler or a square baler the shape will vary. the round baler has giant continual belts that just keep rolling and rolling the hay around compacting it untill its what you see as round bales.
you bale your fields so that the grass can be moved, and that you can keep it for use in the winter time.
I've heard it's done this way because hay in square bales can spontaneously combust. There is less chance of that in the round bales because air cannot get in.
Aside: Don't the round bales look like large Shredded Wheats?
it is rolled into large bales in order to move to feed livestock in the winter. they have expensive equipment to do this.
New papers come from them.
Farmers have switched from bales to rolls simply because the rolls are more efficient. They have a loader which sticks a big pole through the middle of the roll and lifts it up to transport it. Much easier than loading and unloading the smaller bales.
