How many of you use RYAN aerators and what do you think of them? I've had mine for about a year now, and I can't tell you how many times this things has fallen apart on me. No problems with the engine, it's mainly nuts and bolts rattling loose. Now just as my year warranty expired a week ago, the whole axle shaft (that runs through the tines) totally striped out. Now I have to wait a week for replacement parts to come in. Just venting!!!
