The Lawn Boy 10604 variable speed, walk behind, self propelled lawn mower uses the same Kohler engine that the Lawn Boy 10603 lawn mower does. This is an overhead valve model that produces 6.5ft lbs of torque from a displacement of 0.149 liters. The engine uses a splash lubrication system to keep the engine oiled and working smoothly throughout operation. The Kohler engine powers the rear wheels on the 10604 which have an 8 inch diameter. The front wheels are slightly smaller and have a 7 inch diameter. The variable speed system makes using this machine quite pleasant in gardens that are less than 1 acre in size.

The Lawn Boy 10604 variable speed, push mower has 2 options for dealing with the grass clippings. If you are in a rush, you can just discharge them out the side of the deck. Unfortunately though, if the grass you are cutting is very long, then the clippings will look ugly as they turn brown and rot on your grass, coupled with the fact that they will make your lawn look patchy. If you want you lawn to look neater, then you are in luck as the 10604 push mower has the option of mulching the grass clippings. The last option is to use the rear attached bagger to collect the grass clippings as you mow leaving your lawn looking spotless.

Buying a Lawn Boy 10604 lawn mower is a good bet as Lawn Boy are such a well known and trusted brand. This is coupled with the fact that when you buy the 10604 self propelled lawnmower brand new, it comes with a 2 year full coverage warranty. Fantastically, the power train comes with a 3 year warranty.  If you own or have previously owned this walk behind lawn mower, then please leave a review of your experience below to give others an idea of what to expect from it.
