I worked on a farm for a neighbor for several in jr/sr high school and did all sorts of "fun" jobs... here's my list....
1. Weed Eating... on those hot summer days when there wasn't any hay to make, the guy would send me and my buddy out and weed eat ALL... DAY...LONG.... ditch banks, around round bale yards, about equipment, everywhere....seriously try holding onto a weed eater for 9 straight hours... it doesn't sound like it would suck that bad, but it really really really does... i'd rather power wash farrowing houses for 15 hrs in a day that do that.... i now have my own place and i hate weed eating for the 10 minutes it takes me because of that past experience... i am forever scared....
2. Power Washing the Combines... mostly because the guy went over them with a white glove test.... its not a tough job, more just never ending...
3. Saw dust... the guy got saw dust from a local mill for bedding the barns...it was super fine, literally dust not shavings... we go get it by the grain truck load... he'd back under the hopper at the mill and we'd be up in the bed of the truck with masks knocking on the sides of the hopper so the saw dust would flow out. talk about a dusty, itchy, nasty job... it was in ur hair, ears, eyes, pockets, EVERYWHERE....6 showers later you were still itching....
4. loading/moving fat hogs..... when the good Lord was creating this world, i think he was up there pondering "what kind of animal can i create to test a man's strength and sanity at the same time"... then he created the pig...
5. Power Washing farrowing rooms.... theres something about that feeling when you aren't paying attention and blast liquid shizzz up from the pit onto your self and the nice clean stall you just finished.... it builds character....
those were some of the worst for me. i didnt mind making hay in the heat or putting it up, or moving snow in the cold..... it did always seem like we'd end up castrating hogs on days i had a date after work tho... if that didn't scare the girl away i knew she was alright...
