Is there any reason I shouldn't do this?
I saw or read about a pasture hay feeder made out of tractor tires. I waste so much hay just putting it on the ground. I don't use round bales, just a couple flakes for each horse, thrown out in the am, when the horses go outside for the day.
You take two similar size tractor tires, put a half to three quarter inch piece of plywood between them. Then bolt them together, including the plywood. Then put drain holes in the tires so they do not hold water.
I was interested in trying it, but was wondering if I have overlooked some kind of hazard in this plan.
The tires would be tall enough as to discourage putting a foot in it. I would use tires that were not so old as to be falling apart.
Is there some poison that tires emit that I am not aware of?
