3-in-1 Cordless Push Lawn Mower - 80 V - 21" - Blue/Black is rated 4.4 out of 5 by 49.
Rated 2 out of 5 by from Ok but I will be returning It sells itself as a gas mower replacement. It's close, but it's main flaw is the speed sensor. It will mow at a lower level till it senses it needs more power for thick grass, then kick up to high speed. That high speed is closer to a gas mower. The mower should have a switch to bypass the sensor to select the speed you want. The mower cut the grass pretty good, but I had some leafs on the short grass I wanted the mower to pic up ( I've done many times with my gas mower), but the kobalt was is low gear and did not do a good gob on the leaves. High gear would have been nice. So close kobalt, so close.

Rated 5 out of 5 by from Clean and quiet A bit of an investment for a mower but it is perfect for an urban lawn 7000 sq ft. One battery did the work on a single charge on a dry medium length lawn, although the 2nd battery was available if needed. When grass is damp or dense, the motor automatically revs up to handle the extra demand which is a practical feature, plus this is where the second battery is needed if you use the mower when it has to work harder throughout. Charging is less than 30 min per battery, so you can charge the drained battery after a change if your lawn is larger. No more hearing loss or exhaust fumes and it is lighter and easier to push or store.

Rated 4 out of 5 by from Powerful mower, great warranty Purchased not too long ago and only used a few times. I have a medium sized front yard but a large rear yard. I was able to mow the front and back yard using only one (of two) batteries which was fully charged. The mower itself is rather heavy. My last two battery powered push mowers had plastic decks and we much lighter and easy to manipulate (plus no rusting). So far, so good. I can't find the serial number to register the product for my 5 year warranty however. I'm sure I'll find it eventually. Battery charges in only 30 minutes thanks to a fan built in to the charger. I purchased it on sale and with additional savings. Not sure it's worth purchasing at full retail pricing.

Rated 5 out of 5 by from Plenty of power Unlike previous battery mower this guy has enough power to get through damp grass that was left a bit too long between cuts! I purchased the weed trimmer and leaf blower and can cut my lawn, weedwhack, and blow the sidewalks without running out of power. I do change the battery part way through, but with the quick charger and two batteries I'm up and running with no delay's. Easy height adjustment plastic deck folds and stands on end for end of season storage i drop my clippings with the mulch mode happy with my blower (damp leaves ok) and trimmer! 80V is key, make sure to get the quick charge (and the other tools can be purchased without batteries) Looking to purchase another set for a second home! Highly recommend.

Rated 5 out of 5 by from Another point rarely menitioned I bought my Kobalt mower in April. With all the rain we have been getting, I have been mowing the lawn twice a week. I am not going to repeat all the wonderful things mentioned about this mower in the reviews. Here is something no one has talked about yet. This mower comes with a wider set of wheels than I have seen on other lawn mowers. Combined with the mowers light weight. it hardly leaves any tracks on the lawn. They disappear very soon compared to the neighbours lawn who uses a gas mower with skinnier wheels.

Rated 5 out of 5 by from Great mower After reviewing many reviews I decided upon the Kobalt 21 80 Volt mower. The mower was often in the top ten push mower recommended and many times in the top three. It was easy to put together right from the box and it is easy to push across the grass. I've kept the mower up two notches to keep my grass longer this summer and so have now cut my grass four times since purchasing it. Each time the worked very well and it is so great to have a second battery ready to go. I can almost cut my front,back and sides of my yard with one battery. I have not had any reason to cut wet grass yet. Lowe's had a great price for the purchase of the mower during the Victoria day weekend. I am very pleased with my purchase!

Rated 4 out of 5 by from Worked out of the box after a short charge. I have a sufficiently small lawn that Idon't fully drain one of the two batteries. The mower folds up easily for storage and the included charger does a good job charging the batteries. The 80v batteries gave the motor enough torque to chew through tall grass and weeds when it needed to. Very satisfies wit the product thus far. Oh ... and the batteries are interchangeable with the other products although the parts are obscure. A google search does not yield the Canadian supplier of other Kobalt tools, else I would have shared it.

Rated 5 out of 5 by from Easy to use and effective Got this a few weeks ago (in spring) and have used it a few times so far and found it to very good. The big wheels make it easy to push on my bumpy yard. The battery life is very good; did both the front and back with one battery and lots energy left to spare. We will see how it is after a full season of use but so far, very nice mower.
