Rated 3.0 out of 5.0 by CoastMower Doesn't bag wet clippings
I live on the coast. If your grass is a bit wet (which it always is on the west coast) the bagger is virtually useless. It just gets clogged in the first few minutes.

Rated 4.0 out of 5.0 by RePete so far so good...
In the late summer of 2010 I was eyeing the lawnboy 10640, the predecessor of the 10603. Unfortunately, it was sold out everywhere. In the spring of 2011 I learned the 10640, which offered a Briggs & Stratton 6.75 HP engine, was no longer being offered and had been replaced by the 10603 which featured a slighlty less powerful 6.5 HP Kohler engine. Figuring the change in engines was due to cost, I contacted Lawnboy who never really gave me a straight answer when they emailed me back. They said they needed an engine manufacturer that could produce a large volume of machines for their mowers. And Briggs couldn't? So I went back to my original theory and concluded that the real reason was cost. Anyway, I researched Kohler and seemed satisfied so I purchased the 10603, figuring a 0.25 drop in HP shouldn't make a huge difference. Anything that is 5 HP or greater is normally sufficient. I used to work in property maintenance/landscaping and all we used were Lawnboys and Toros so I figured I couldn't go wrong as they are both excellent brands. And so far so good...the 10603 started on the first pull as promised and the height settings are much easier to adjust than on older lawnboy models. I cut my 3" lawn down to 2" using the bag and the machine left no clippings behind. The manual suggests that you only tip the machine on it's side when the tank is empty. I tipped it over on it's side even though I still had some fuel in there (dipstick side down, air filter side up) to clean it out and there were no fuel leaks whatsoever. I also like the large fuel neck, makes it a lot easier to fill. I chose the recoil model without the transmission because I feel that the more components you have the more likely things are to break. I chose this model because I don't care about an ignition start system and I don't need a transmission because my lawn is flat. So the 10603 suits me just fine. However, if you live on a hill you might want to consider the 10604 which is the self-propelled version. However, one of the downsides of the 10603 is also mentioned in a review for the 10604, namely that when you remove the bag the grass clippings make a big mess because of the angle they use to clip the bag onto the machine. I haven't used the mulcher yet so I can't comment on that. Lawnboy also offers a side discharge attachment too but you have to order it (free of charge). The only other downside is that the deck is not aluminum but not a huge deal. And the flap at the rear is a little flimsy, I am thinking of getting a 3/4" bar and zip tying it to the flap to add some weight for better striping and to keep it from going under the deck. The manual states to empty all fuel before winter storage but won't this create moisture in the fuel line? I will probably just use fuel stabilizer. All in all, I am happy with this machine and would buy it again.

Rated 5.0 out of 5.0 by Greg Might as well replacement it
I intended to replace the auger belt, but once I figured that the cap for the snowblower was removed (which can be tedious), I also figured it made sense to replace the sparkplug. Just make sure you have a deep enough hexagon socket piece to loosen and replace the plug.
