My lawnmower. It would work perfectly if Sears made the right replacement parts for it. The primer bulb won't stay seated, so I have to continually pound it back in with a hammer and screwdrivers, or it won't start. Sears stopped making the grasscatcher style that it came with, and the new one I had to get is way too small and falls off at the slightest bump, which leads to a lot of starting and stopping. The lever to the kill switch has broken, and Sears no longer sells that part, so I have to wedge a block of wood under the switch to keep it from shutting off. This, of course, makes it unsafe to operate. I hate Sears. The time has long since come for this horrible shell of a company to die and let something competent take its place. I hope their next board meeting is interrupted by a pack of rabid wolves who assrape the corporate officers, and my hatred for them burns like the fire of a thousand suns.
Other than that, I have no complaints.
