Howdy,
Myself and 2 of my neighbors have a combined bag total over 70 bags. I have only thrown out on bag that i destroyed when it slipped off the end of the fork it ripped 2 of the loops off before i could set it down. 10 of my bags are now 5 years old and ive slowly added to the count. The oldest bags are showing signs of wear degradation. Some small holes from wear and mice but they continue to hold up. I have another one with about a 6 inch tear after i accidentally backed into it and knocked it over with the tractor.
