Rated 5 out of 5 by from LUV THIS MOWER began using about 6 weeks from end of season and have had no problems. been using electric for many years and this seems to be even better than older models. got self propelled for my partner but i prefer to push. slowest speed seems to sometimes be still too fast for quality cut i like. only negative thing i've found. pretty much love this machine.

Rated 5 out of 5 by from Great supplemental mower for a large yard. Super easy to use and almost no maintenance. This works great for a supplementary mower for our yard. We have a little over an acre so it won't handle the whole thing at once, but the back yard gets too wet for our riding mower sometimes so I wanted a walk behind also. The battery doesn't last for the whole back, but I already had a 4 amp for my Greenworks chainsaw so both combined took care of tall grass with leaves, maybe 1/4 acre or about 20 min.

Rated 5 out of 5 by from Good mower Great mower does everything I need. Only issue is if using the self propel you have to let off early in order to reverse. If you do not the wheels lock up and you can not move it backwards.

We have a hill that is difficult to mow horizontally. we would like to disengage the self-propelled feature when mowing down hill, and re-engage it while mowing uphill. Is is possible to easily switch on and off the self-propelled feature while mowing?

Asked by: RitaH
Hello RitaH, Yes you can operate the unit without the self-propelled feature. Do not pull the lever associated with the propelling feature and the unit will not propel forward. It is The run time will last longer without the self-propelled option being engaged. It is recommended when mowing on a hill remember to mow across rather than up and down. Walk behind mower units should not be operated on slopes greater than 15 degrees. This is not a limitation of the unit, but rather to ensure safe footing for the user.
