Old farm stuff! cool! The old metal seat is like the one on my grandfathers hay rake. I sat on it as a youngster being pulled behind his old tractor, we had to hand crank it to start that thing. After the hay was cut and dried he would pull me on this rake. It had large curling tines across it that were normally in the down position. When he let out a yell I would stomp on the foot pedal and they would raise up for a bit and then drop again, thus creating rows of hay. we would later pull a ramp type rake and a wagon behind it and hand stack the hay and cart it back to the barn. I'm still diggging up this old stuff at the farm.
