Rated 3 out of 5 by from Gets the job done Overall this mower does a great job with my lawn. The motor does not bog down like my old Honda and keeps up with the mulching. However, it is very difficult to start when hot. If I have to shut the mower off it takes 6-10 pulls to get it restarted. Since I have to turn the mower off to transition between levels of my yard this is more than a minor inconvenience.

Rated 5 out of 5 by from Great Reliability! I have Briggs and Strattons on both my push mower and my riding mower and I have never had to do any work on either of them. I change the oil, oil filter, pre cleaner, air filter, fuel filter, and spark plug(s) on each of them every year and drain the fuel from them at the end of the year and they always run great! The push mower is a 1991 John Deere 14SZ and the riding mower is a 2007 John Deere LA145.
