[AT] unidentified horse drawn equipment

[John Hall]

 While on a family outing at a pumpkin farm, I briefly saw a horse drawn 
piece of machinery I couldn't identify. It is built similar to a stalk 
cutter but instead of a large drum with straight blades, there are 2 or 3 
rows with star shaped discs. The rows of discs are straight, not angled like 
a harrow. It looks sort of like it is some sort of an aerator. It is a bit 
east of me so that puts it on the edge of peanut and cotton growing regions. 
Any ideas?
