Lawn Boy 10604 149cc Gas Self-Propelled Lawn Mower Review

Looking for a powerful, self-propelled mower that is simple to navigate on uneven lawns and powerful enough to handle any lawn job? The Lawn Boy 10604 variable speed self-propelled gas lawn mower is a great choice for those with uneven terrain or are just looking for a self-propelled, gas-powered, mower.

Lawn Boy has three variable speed, self-propelled lawn mowers in their 2011 line; the 10604 (reviewed here), 10605, and 10606. Besides slight variations in weight, all models are nearly identical.  The 10605 is the only mower in this line to offer automatic blade stop. The 10606 is the only model to come equipped with an electric starter. Also available is the 10603, which is not self-propelled.

Positive Customer Reviews

This is my first self-propelled mower and it's great for my yard. Half of my backyard is hills and lumps mixed together with trees and shrubs. This mower has no problem plowing through thick grass and the rear wheel drive makes it easy to go up hills.
