Sun Joe ION100v-21LM-CT Cordless 100v Self Propelled Lawn Mower

Sun Joe has a wide range of outdoor power equipment and one of their latest editions is a new 100v self propelled cordless lawn mower, the ION100v-21LM-CT. Battery powered mowers have come a long way and this new model from Sun Joe looks to be a good competitor with the offerings from other top brands.

My thoughts. While I haven’t made the switch from gas to battery powered lawn mowers yet, there’s no doubt in my mind that for many people battery powered mowers can be a full gas replacement. This new mower from Sun Joe has several top features such as a 100v brushless motor, a variable speed self propelled system, a 7 position height adjustment, and the option to side discharge or bag the grass clippings. One other thing I like is the collapsible handle which will make it much more compact than many other mowers for storage purposes. Overall I think this should be a great option for users of other Sun Joe 100v tools and batteries.

A big thanks to Cody Robertson for spotting!
