I got my new walker perfaerator a few weeks back. I have only done a few lawns and now the tines don't lift up enough to get off my ramp. I ended up tweaking the arms that lift the tines as they jammed in the trailer trying to get it unloaded. I am now out beating the heck out of a brand new machine with a sledge hammer to try and fix it. Not to mention that after the first lawn half the nuts came loose. Anyways for three grand I think the thing should be able to back off a trailer and not fall apart in the first week although my dealer seems to disagree. Anybody else had thins problem???
