I bought a set of Titan tracks for my TL150. I don't use it very much, but within 80 hours one track broke in half. I set it aside while waiting for a response and put an old track on it to finish a job. Within another 10 hours, the other track broke just like the first one. What can cause this? The track are in good shape, just broke. Titan refuses to warranty them and I don't know what to replace them with. I contacted them for 3 months and they did not answer me until after the warranty had expired. I contacted the BBB and filed a complaint, which they never responded to.
