Like others, I needed to know the lowest measurement setting from the ground to the operating button with the mower attachment and trimmer in place. For some unknown reason, the community answers seemed to avoid such an easy question for those who owned one?! With that said, I just purchased my own to get that exact answer with a measuring tape. The LOWEST MOWER HEIGHT (from ground to button pressed): 22-1/2 inches. The HIGHEST MOWER HEIGHT (from ground to button pressed): 31-1/2 inches. **Due to my very own physical needs, the lowest height works perfectly for me! Fortunately, I did not have any of the 'troubles' that some have reported with theirs. If it works as it all did with my first use on a small yard today for even a season or two, I would definitely purchase again! Although it does kind of sound like a small shop vac in use, it is absolutely adorable and FUN for me to use. I love it!! It does look like a toy and is nearly identical to vacuuming (with both physical motions & width). So those that are impatient, hate vacuuming or want to look 'manly', may not appreciate this trimmer/mower like I already do. Did I mention that I I love this thing! :) However, as not to wear down the thin and very narrow plastic lip that holds the trimmer into the mower attachment, I personally won't be pressing the trimmer into the mower attachment until it "clicks" per the instructions. Instead, I simply press on the pedal and gently seat the trimmer all the way in before releasing the pedal to lock it in place. Noting again, that's just my own suggested solution to hopefully prevent that thin plastic 'lock' from wearing down so easily, or as I see that it probably could otherwise. Further, the trimmer seems to hold in place just fine when pressing the trimmer handle down to make turns (just like placing the weight on the back wheels to turn a vacuum). To 'lift up' on the trimmer handle when mowing, is when it wants to detach from the mower --so don't do that people lol. Just like every electric tool that I've ever owned, it does NOT come with an extension cord (and it makes me laugh that anyone would expect it to). However, since I wanted an extension cord designated just for this unit, I also purchased what did NOT work --and that was a 50 ft 16AWG Yellow HUANCHAIN brand through Amazon at the same time as well. To my disappointment and even trying to force it further into the plug hole, that extension cord does NOT and will NOT make a tight enough contact to fit but for 'brief' contact spurts. At first, that was a big GRRR there for me because the mower kept cutting out before I realized it was that extension cord that was barely making contact. Okaaay.... **Instead though and most fortunate for me, I ended up using my older orange extension cord (that most of us have laying around) that has a slightly narrower plug encasement ... which seats all the way into the plug for continuous contact well and fits perfectly tight! With my recent experience: If it feels slightly wobbly, kind of loose or pulls out too easily... just forget it and try another extension cord plug! You're welcome. Lol Again, before getting super frustrated with the extension cord constantly coming loose from the plug (like I did with the brand new yellow one), you may want to try to find an older style or better fitting extension cord first (even if to take the trimmer to your local hardware store to try one there)! See my extension cord pics as example: Orange (narrower) = Perfect & Tight Fit! Yellow (chubbier) = Frustrating, Loose & Horrible Fit!! Lastly, my reason for purchase: Living in an apartment with a small yard has became just too ridiculous annoying every year to 'wait' for yard maintenance not even mowing until the weeds are almost 18" high and allowing the clippings to just fall where they may for their tenants to just track long grass/weed clippings into our cars and apartments -- I finally had ENOUGH when a thorn weed recently caught my pant leg causing me to trip and fall! With this fun to use, light and nifty little edger/mower that I can enjoy taking care of my yard weekly and all by myself... I won't and NEVER will want such careless "yard maintenance" in or around my yard (or vehicle) again now anyway! I'm not done yet but just after mowing the whole yard once & quickly edging to 'test' it today, my yard already looks way better than it ever has before! I'm HAPPY and very pleased with this fun little B&D trimmer/mower being my new 'toy'! The only reason I'm not including pics of the results with its use on my yard today is due to some privacy concerns but it already looks GREAT! Yet, I hope my lengthy review helps answer some of the questions that I had prior to my having to purchase it to find out for myself anyway. I'm sure glad I did though! I don't enjoy raking so to prevent that, I will just be sure to mow weekly through the growing season because I CAN and will enjoy doing so, too. Just make sure you get a tight fitting extension cord and well then . . . Happy mowing the easy way!! :)

I love this compact 3 in 1 mower. It is very easy to use. It was easy to put together--screw on the safety guard to the weed-whacker, snap the extra handle on the weed-whacker, adjust the height of the wheels on the mower body/deck, and place the weed-whacker in the mower body./deck Super simple, but I recommend checking out videos online that review this mower and show how to set it up. This mower is very light weight--13.9 pounds, according to the Black and Decker website, where you can find all the specs and other information on this model of their mower. None of my extension cords fit the recessed plug on this mower. A search of the reviews led me to purchase, here on Amazon, Woods 50ft Outdoor (2-pronged) extension cord (16 gauge, 13 A, temp range -40F to 167F). Works great! Highly recommend this Black and Decker mower, as well as Woods extension cord.

Product worked very well, fast to set up and get started, however you will need to buy an additional extension cord because the product didn’t come with one. Easy to use on all grass types & the edge trimmer does wonders on stubborn weeds. Was able to do a full front and back of my home in less than 2 hours

This product is not worth buying!!! I bought it because of its interesting design and its price and the brand name and because I have a small yard and our lawn guy pissed us off because he wanted to charge us $35 every 2 weeks whether our yard needed to be cut or not. This design was a great idea but needs to be done better. The first and biggest problem is that the 2 pieces come apart too easily while in use. The second issue is that the line only lasts for about 1.5 cuts front and back. Our lot size is about 7000 sqft including a 1700 sqft home on the lot. I believe the backyard which is the biggest of the 2 yards is about 45x35 feet and the front is about half this size. The trimmer grab handle needs to be able to rotate for edging. The replacement spools are expensive and getting harder to find. Walmart is now selling their own line of Lawn Care equipment and no longer sells B&D replacement spools. I purchased the less expensive system that uses an extension cord and it is very easy to run over the cord which will damage the cord casing. I made the decision not to buy the rechargeable system because the reviews stated that the batteries only lasted about 20 minutes each with an added cost of around $70 almost double what I paid. My lawn takes me about 3 hours to cut with about 2 15 minute breaks included in that time frame with this machine. The deck has no adjustment for height and so the grass is cut too short which causes it to burn easily in the hotter months. There is no grass catcher so it leaves clumps of clippings all over the yard depending on how high the grass is when you cut it. The trimmer being used as a blade is not very effective for cutting grass so you have to go over the same spot several times to get an even cut so that your lawn looks uniform. Also the width of the deck is considerably smaller and doesn’t cover as much ground. The trimmer loses its effectiveness as the line shortens so you will have to constantly stop and release more line several times to finish the task of cutting your lawn. If you have to have something cheap in a pinch it does work and at $89 I have already paid for the machine with the savings from cutting my own lawn and there is a lot of satisfaction afterwards when you know that you have cut your own lawn to your own level of quality. So unless you are very patient and have some extra time be prepared for at least 3-4 hours in triple digit heat and many moments of frustration especially if you’re located in Texas like I am. I’m in the Dallas area so it’s probably going to be even hotter the closer you get to Houston. I will probably be replacing this machine with a more expensive larger rechargeable mower with a bagging attachment and a much better quality rechargeable trimmer. A blower is also a must because you are usually too tired to sweep 🧹 and it takes forever too. You get what you pay for but I have paid for the machine with the savings from 3 cuts at $35 for the service.
