I have a lot of Black Berry to clean out. So far I haven't had a flat on my front tires on my MX5100 but I was thinking about a guard of some kind. The old farmers would fit a old tire over the front tire,I guess it was a guard. But I wonder how they did get that old tire over the good tire? That maybe something that I don't need to worry about. Any help would be good.
I've never known of anyone getting punctures in tractor tires from blackberry thorns. Honey locust thorns are quite another matter.
Regarding thorn protection, it was once common to install tire liners in tractor tires, both front and rear, to prevent thorn punctures but such practice has gone the way of the doo doo bird with the advent of tubeless tires.
Tire liners are made of ground down used tire casings and are installed between the tubes and tires. In place, they continually move slightly with use and shear the ends off of the thorns that penetrate the tires.
I used them on all of the front tires of my vintage Ford mowing tractors with tube type tires. Thorn punctures were common before such use but in 35 or 40 years of use, I never had a thorn puncture with tire liners.
Tire liners for rear tractor tires are NLA and those for front tires are hard to find but still available from Gemplers.
