Please don't post in two threads with the same problem, which in your case makes no sense, as the threads do not stay together. Sounds to me like a setup problem, which would then take us in two different directions for a solution. If you bought your mower from a Big Box store, and you had to set it up, then I would go back to the setup procedure and double check everything. If you can't find the problem, then I would go to a dealer and see if it is a non setup problem to be fixed under warranty. If the Big Box store set it up take it back to then with your complaint. If you purchased it from a dealer, take it back to the dealer and have it fixed under warranty. If you come back with more info, make sure you post the units model and serial number.
