superb service
Thank you for having all the desired parts for keeping my (2007) lawnboy in tip-top shape. Not sure if any lawn mowers are made with an aluminum case like my lawnboy which also has a bullet-proof Honda engine. Again, glad you are there.

Wrong part
Ordered the rear wheels according to wed site. It said these would fit my mowers model number. They did not (wrong gear size). Called and they asked for the serial number, which the website didn't mention. Sent the correct part and fit perfectly. My only complaint was they required me to pay for return shipping. Since the website stated that the first set was a match, I felt maybe they were partly at fault. Return process was very professional

The new wheel has new "cogs" for self propelled, so I simply replaced the wheel. I am not a "do it yourself person", but this was very easy to do. I was very impressed with eReplacement's ease of ordering, courteous and fast service. Would recommend them highly. No special tools were required. Just a socket wrench.
