That was back in the good old days before the Progressives changed the names of the meals. Working in the hay fields it was breakfast at home. Then around 10 AM lunch, noon dinner, 3 PM lunch, 6 PM supper, and sometimes around 8 PM a hearty snack.
Those were 100 lb. square bales, hay bales stacked 4 high on a hay rack. 80 to 100 bales to a rack. The bed of most hay racks were 2 1/2 to 3 feet off the ground. Front two rows meant that working from the ground you had to put/toss the bales up 7 or 8 foot. It took 3 people of load the hay rack. One on tractor, one on the rack stacking bales, and one on the ground.
Work for one farmer for a hay cutting. Next farmer for a hay cutting. Rotating farmers through the summer. It was pretty much a full time job. Back then it was mostly manual labor.
