I feel like I am about to jinx myself by writing this review after one mow. For background, for the past few years I have been using a Greenworks 21inch deck mower. The batteries were awful on it, it cut awful, it seemed like it would cut out when it sensed I was about to get to the taller bits of grass. It honestly turned me off of buying an electric mower because I felt they were all the same. Que this mower. I read the reviews, figured it was worth a shot and wow I can’t believe I dealt with that Greenworks mower for this long. The LawnMaster mower was easy to put together and there was even juice in the batteries. When I started mowing my front lawn, I was amazed that there was no pieces of grass that it missed, unlike my last mower. The LawnMaster feels very lightweight and I am amble to maneuver it with ease. The size of the deck is perfect since i don’t have a huge yard, and it’s very quiet. So I’m suspiciously optimistic and if it continues to impress me, you better believe I’ll be buying a trimmer from LawnMaster too.

I am pleased with mower. Easy to put together and handle

I have used this mower twice and so far am very pleased. It is light weight and will mow my small front and back yard with leaving 40% left on battery. I did have a scare last time I used because mower stopped on fully charged batteries and I discovered the safety key came loose and was able to put back in and finish. In my opinion the key could fit a bit more snug

So far, so good!

I received the mower quickly and on time. It was in great shape coming out of the box, and the minor assembly required was easy and well spelled out. I fully charged the batteries before trying out the mower. Setting to deck level 3, I was able to cut my back yard easily and completely which took me about 30-35 minutes. There was still significant charge in the batteries. For a small to medium yard, as in my case cutting the front one week and the back the next, this mower works great!

Nice, but not heavy duty

Nice and lightweight. Very simple to put together. ok for small yard. Mostly all plastic . Works fine out of the box ,but I don't expect it to last. Small blades. Not good for tough weeds.

Best sub $150 electric mower

Well built, packaged, and easy to assemble. Bought for a smaller lawn and does the job in a few passes. The raising and lowering handle is much more convenient then moving wheels up and down like similar models which makes adjusting height super quick. Has plenty of power to mow an average lawn. Can't speak about huge weeds or small plants if you let your yard get away from you. The power switch is very light to operate so hopefully it lasts. So far I am happy with it's purchase. The only reason I'm giving it a 1 star deduction is pulling it backwards it seems to get caught near the grass catcher which requires you pull up on the handle lifting the back wheels if you need to go backwards more than a few inches. Not sure if this happens when you raise it to full height. Will revisit if things get better or worse.
