I am old enough to been able to put hay in the barn loose. A Case VAC exp pulled the wagon and loader till the wagon was full.
Pick up pulled the wagon it the barn and inside. A system of ropes, a carrier and track in the roof of the barn got the hay off the wagon and where you wanted it in the loft. We tried different types of things to remove the hay.
hay track carrier.
This one is what we used mostly.
Used these called Eagale claws, but ours had 3 tines.
There were a two tine deal called a harpoon also. can't find a picture of one though.
With the 4 tine graple it took about 4 loads to empty the wagon. the hay was lifted just enough to clear the beams to start, pulled to ther back of the loft. Long poles with a big spike in it was used to get it swinging then tripped to release the hay hopefully where you wanted so there wasn't much fork work to get it there.
We finally got a old T 45 IH baller in 1963 or 64.
Last hay I did was 1967 as I was in the army in 1968. Still looking for the friends and family that requested me for that job.
