    • “It was a bit mis leading when the description stated it could cut from 1.x to 2.x as I expected that to be a range just like my tractor mower. However, all you can do is move the wheels from a low position to a higher position.”

    • “There are 2 settings for closeness, which are ok, but an additional lower setting would be useful for me.”

    • “Raising the wheels.. no good explanation.. pull on the front and back underneath axels and the spring loaded thing will go to the slightly higher or lower setting near the wheels.”

    • “Adding to the ease of use is the height adjustable shaft that makes it easier for both of us to comfortably use it even with our 11 inch height difference”

5 reasons not to buy

  • The mower attachment is made of plastic, which has made some people worried about how long it will last. Users are being careful with it to prevent potential damage and make it last longer. (16 reviews)

    • “Due to the mower attachment's plastic construction, I plan to be careful with it in order to prolong durability.”

    • “You cannot bang this unit around too much, it is only plastic.”

    • “I had my doubts and thought it would be flimsy and cheap.”

    • “Some people also mentioned that it felt flimsy in the mower deck.”

    • “Mower accessory is a little flimsy, at least this part would have had a better stronger material”

    • “could be a little more durable.”

    • “It's just a weedeater in a plastic form with wheels”

    • “In two years I've gone through two of these because the motor burns out. If you're doing more than really small jobs the motor gets hot and melts the plastic that holds the magnets that drive the motor.”

  • At least one user said the mower didn't last very long, mentioning it stopped working after a few months of light use. This raises concerns about how long the product will last and how reliable it is. (12 reviews)

    • “The mower of the season has DIED. Unbelievable. I've only been using it 1-2x a month.”

    • “But it died so I bought another B & D”

    • “I found that it stopped working once when I had the platform on it -- I think it overheated.”

    • “Lasted 3 months.”

    • “after 6.5 yrs it died. Motor seized. It suddenly sparked, smoked and chocked on it's last blade of grass unexpectedly, shockingly fast yet peacefully... Wish it lasted longer.”

  • Users have mentioned that the highest setting for cutting grass isn't as tall as they'd like. This is a problem for people who want to keep their grass longer. (10 reviews)

    • “It also would be nice if the height were a little higher as I like to keep my grass higher than this allows. My slope looks like a perfect golf green, but I may need to water it more often.”

    • “One restriction is the adjustment of the unit only gives you 2 level choices, low or lower.”

    • “The base also only offers two height settings though the trimmer can power through nearly any grass height.”

    • “height adjustment goes from a little too short to “golfing green” short”

    • “It's pretty poor at cutting tall grass.”

    • “Not ideal for cutting St. Augustine, because it cuts VERY low to the ground”

    • “Would be nice to have one that cuts 4inches which is the optimum height for tall rescue grasses in my area.”

    • “I wish the cutting platform could be raised higher - there are only 2 settings, and they are both very low.”

    • “The highest setting on the trimmer mower is a little shorter than my highest setting on my regular mower.”

    • “The one criticism I have is that I wish there was more clearance, the cutting heights of 1.6" and 2.4" are too short, especially in the fall.”

  • For thicker types of grass, users might need to go over it a few times with the mower. This suggests that the mower might not be strong enough for tougher lawn care jobs. (10 reviews)

    • “A more powerful/faster motor would cut better when line is under load from thick grass or weeds, again an exit port would help this as well.”

    • “It doesn't like thick green weeds and takes some concentration to cut through those.”

    • “If your grass is very long, it will take a couple of passes to get a nice clean cut”

    • “After few months I decided to buy a real lawn mower, this is very flimsy and weak, even for a small yard”

    • “Going back and forth over the spot from two directions will get it done but it's not pretty and it's adding a lot of passes to the already large number of required passes since the 'mower' width is only 12".”

    • “Some difficulties with larger, thicker weeds, but was able to cut through it”

    • “The first pass would leave chunks of uncut grass because the cut grass was getting caught under the mower deck preventing the line from cutting.”

    • “You have to go back and forth to get a uniform cut on thick grass/weeds.”

    • “I had weeds (some grass) 2 feet high and THICK.”

    • “It is fine if you maintain your lawn, but I have a habit of cutting it when it looks like the amazon jungle. It still cuts, but it takes several passes.”

  • Multiple reviews said that the wheel height adjustment, which is held by a spring, can easily go back to the lower height if it gets bumped. This means users have to be careful and often fix the height, which can be annoying and interrupt the mowing. (5 reviews)

    • “A slight problem is that the wheel height which is held by a spring pops back to the lower height easily so I have to be careful that doesn't happen when I bump it up and down over the tree roots and higher sidewalks or curbs.”

    • “The issue with this is that the low position actually drags the device on the ground making it difficult for the wheels to even roll thus the adjustment is completely pointless.”

    • “Raising the wheels.. no good explanation.. pull on the front and back underneath axels and the spring loaded thing will go to the slightly higher or lower setting near the wheels.”

    • “This requires users to be cautious and often to correct the height, which can be a nuisance and disrupts the mowing process.”

    • “Also, the wheels will often reset to the shorter 1.6" during mid mow, which caused some damage to my lawn at times.”
