Guy"s, I tried to post his a few days ago and some of you thought I was a scammer. Some got it right. I am a missionary to Cambodia where we have raised 11,000 orphans over the past 15 years. Now, I did buy D3-B chains from "Crawler Heaven" in NY State. But I have a rice combine (we raise 500 acres of rice to feed the orphans) from him a few years ago, but he seems to be out of business. Now, here"s the deal, I bought a rice combine, made in Thailand, that uses D-2 chains. In this sandy loam mud of Cambodia they don"t hold up. I"d like to find a set of sealed (oil chains for a D-2. Are they available??? See website: www.fcopi.org if you think I"m a scammer. Photo attached.
