in Montana making hay in an unusual way, with unusual vehicles, and getting help from Amish guys from Pennsylvania (skip the 1st 40 seconds)

I believe the narrator said this is known as a hay stack type storage, and that 3 storey tall gadget is a known as a beaver slide. The rake on it is moved by the winch or motor of this green Chevy that seems to be a WW2 military truck similar to the Dodge Power Wagon

 

because the field is soft due to high groundwater or recent rain, they use these front wheel drive (with chains on the tires) car frame looking home made scooper/tractors to gather the hay and push it sliding across the ground to the beaver slide / lift

the little orange tractor pulling the hay rake is the same as my grand dad's early 50s Allis Chalmers Model B https://justacarguy.blogspot.com/2018/01/does-anyone-recognize-what-manufacturer.html
