Have you tried using a pot-in-pot refrigerator?

You also have to be flexible in the weather you will be working in. You won’t be working on warm sunny days all the time; you will have to work in the wind, rain, storms, and maybe even in the cold and snow if you find a job up north. You also have to be able to work independently without supervision or anything of that sort, and even remember what you are told and certain rules that exist on a farm and ranch. There are certain rules that you must know about working around machinery and livestock, since farming/ranching is in fact the second most dangerous occupation a person can have a career in: Mining comes first. Such rules are mapping out an escape route when working with potentially aggressive cattle, never step over a running PTO shaft, be aware of your surroundings, make sure the machine you are operating is out-of-gear (or turned off) before you get off said machine, the list goes on.

What duties and job requirements are for a certain farm or ranch depend on that farm and ranch, since none is different and each job changes from day to day and season to season. You have to flexible in that aspect too, since you won’t have just one job to do like factory workers typically do. The bottom line is that you have to be eager to do HARD WORK every day, and be there on time for milking, haying, checking cattle, etc. You can’t be scared to get dirt or cow or horse crap on you or under your nails or on your clothes, or oil from having to oil machinery, or anything else that is considered dirty, gross, etc. And that includes birthing membranes too during calving season if you have to help pull some calves!

Don’t forget proper clothing either. Nothing that’s loose-fitting, nor any fancy-dancy shoes either. Keep your hair back in a pony-tail (if you have long hair) or under a hat or cap, have good working jeans, shirt, jacket, boots (don’t have to be cowboy boots unless you are riding horses, where they are a necessity) and good gloves (roping-type gloves are the best, not the ones with the hard cuff over your wrist). You pretty much have to dress up like a farmer/rancher in order to be a farm-hand or ranch-hand.

I would also sit down and do a bit of reading too, to get you acquainted with the various terms and details about everything farming and cattle. CattleToday.com is a great cattle-related site to read up on, and Storey’s Guide to Raising Beef Cattle is another good book to read, since it caters to inexperienced newbies like yourself.

And most of all, don’t be afraid to ask questions. The only stupid question that exists is the one that wasn’t asked.
