this is for feeding grain & dairy ration to 4-h animals. 2 pails of each equaling 2 trips from trailer to pen. this takes about ten minutes every day, and for 200 days(aug - may) of feeding. * not: i did not feed every single day of the 200. i was away for a few days sometimes so 6 hours is a lot less then what i wopuld have fed, but still a fair amount of lifting.
