I was not sure if this mower would work for me, seeing as my lawn is "too big", bumpy, and pretty weedy as I don't use chemicals on it.  But I took the chance and am very glad I did.  It's much easier to manage than the gas mower I was using (not self propelled),  and does a good job on the lawn.  If you are looking for a perfectly even lawn this may not be for you, but I don't mind an occasional weed sticking up here or there.  The higher height setting seems to allow the mower to go over most small twigs, which was another concern of mine.  I mow each "section" of my lawn once per week, so the grass does not get too high.  Also I switch mowing directions each time.  If you are not able to keep up with your lawn this probably isn't for you as it does best when cutting about 1/3 of the length of the grass.  Using this mower might take me a bit longer than using the gas powered one, but not by much.  And it's a whole lot quieter and easier to maintain.
