The self propelled mower is rear wheel drive yes? How to back up in corners? I'd decided to buy one this weekend but I've always owned front wheel drive where it's easy to raise the front wheels to back up.
If you let go of the drive lever just before you get to where you need to back up and let the mower "coast" for a few inches, the propel mechanism disengages and you can then pull it backwards. Many people report a short learning curve to get fluent at it, and once figured out it's no problem.
