So you thought Kobalt only made tools.  In fact, they have a line up of various lawn mowers.  Here we are covering the 40V double battery lawn mower.  When you buy this lawn mower you get a 4.0 ah and a 2 ah battery.  So if you are mowing and you run out of juice, you don’t need to wait around.  You can do a quick charge or better yet have one ready.  If you read the rest of our mowers from mower week, you might see a similarity in this mower and the Greenworks mower.  That is because they are made by the same company.

Now this didn’t win our top battery mower but it does have a lot to brag about.  The mower is plenty enough powerful for the average homeowner.  While I am not impressed by the quality of the handle, I am impressed by the power management system.  When you start the lawn mower up you can hear it really rev up.  While the mower is quiet, it will get even quieter in about 5 seconds.  You will be able to hear the mower power down.  In fact, we thought one of the batteries was low, but we were wrong.  As the mower needs power, it will rev back up to help cut the deeper grass.  This is a cool way to manage the batteries and make sure they get even longer run time for your mowing experience.  If you are looking for a battery operated mower and don’t mind waiting 60 minutes for a fully charged battery or mind a cheaper handle, this is a good buy.  As for the quality of the mower, it seems to be pretty good.  The twin blade system is pretty cool.  One thing to note, which I am sure I am wrong, I know this is advertised as a 20″ cut, but it doesn’t seem like you get a true 20″ cut. However when the grass starts growing in Chicago, we will surely find out.
