I bought a second one thinking it was my fault that this lst one fell apart . Well, the same thing happen to the second one. Didn't last one season. You adjust it from edger to trimmer. The hood came disconnected from the motor on both rybobi's. It's frustrating because the motor is still working perfectly, but it's impossible edge now and you can trim but debri is flying everywhere and it's so unsafe to use it this way. The hood actually broke away on both unit's and both units only lasted 10 weeks.
