During assembly I noticed one of the wheels did not slide on the axle all the way to the end but left a good 1" gap short.  I called customer support and was told that a sales rep would respond to my concern. I asked to speak with a technician and not a sales person.  The sales rep responded that this is how it is designed without answering my question.  I have assembled many garden implements and have never seen this.  What will happen is the axle end will round out the inside of the wheel over time.  Poor design and even a poorer response from the manufacturer.  Do not recommend.
