I have a 6 or 7 year old 21" Troybilt. These days they're making them almost completely automatic, no adjustments at all. With this one, the only adjustment is blade height. To start it, you squeeze the lever and pull the rope. No switch, no squeeze bulb, no choke. The switch is the handle lever. When you release it, everything shuts off instantly. When it's running, there's another lever to engage the drive wheels. It's easy to start and has been very reliable.
Most of my mowing is with a garden tractor. I use this for trimming so it doesn't get a lot of use. It's been very good for what I use it for.
The only problem is the grass chute. It has a flapper door that closes for mulching. If you want it to eject the grass, you lift the door and attach the chute which takes all of 5 seconds. The chute is the problem. Any light bump and it falls off.
