Black & Decker CM1836 Review-disc

Black and Decker CM1836 PRICE This is going to be an in-depth Black & Decker CM 1836 Review. This cordless electric lawnmower is 18 inches and 36 V. The B & D CM1836 has over 200 reviews on Amazon alone and it is still pulling in 4.1 stars. With that many reviews, that is a very good rating.

This mower has been around a little while and has proven itself to be a solid investment by most of those that purchase it. It runs on a 36 V system and can cut up to one third of an acre. From my experience in doing these lawnmower reviews when they say one third of an acre they mean a 1/3 acre lots minus your house area. So if you have one third of an acre to actually cut this might not quite do it.

There have been a couple of versions of this exact model and it seems that Black & Decker has gotten all of the bugs out and do the percentage of positive reviews is better now than when it initially started with version 1.

Read the rest of the Review for an in-depth look or check the PRICE on Amazon.

Motor and Power

The CM 1836 uses a 36 V system and a redesigned powerful motor to tough grass with ease. Black & Decker also redesigned the blade on this one and their other cordless mowers to be more efficient and leave a better cut. It also seems that the lifetime use of the blade was not affected either redesign. There’s plenty of power for a medium-sized yard.

Start Mechanism

Black & Decker CM1836 Safety

This mower uses a safety key and bail system to start the motor. This was done to ensure no false starts and if you fall you should release the handle immediately do not try and hold onto the bail wire if you happen to slip. This way the motor will stop almost instantly when you let go of the bail wire. Under no circumstances should you override this safety system.

Safety Features

Beyond the start mechanism there are several other items designed to increase the safety with this mower. The rear door has a spring-loaded mechanism so that it can not be held open without the bag and place. This ensures that you will not run the mower with the discharge pointed at you. It also has a rear flap for when you are mulching to keep stones or other items from flying toward your feet.

Stay smart and follow the directions and you will be safe using this lawnmower. The following link will go to the Black & Decker CM 1836 manual so that you can take a look at that before you purchase.- (Return to Top)

Deck Size and Material

This Black & Decker electric lawn mower has an 18 inch cutting back which is adequate for a medium-sized yard. It is made of a durable polymer plastic that is guaranteed for life.

Black & Decker CM1836 Handle

The handle is ergonomically designed with adequate cushioning and it does fold over for compact storage. It only folds in one place so it may not be as compact as other models. This is not a small mower so if storage is a problem or your yard is very small you may want to look at a smaller model in the 14 to 16 inch range.

Mulch – Bag – Discharge

This lawnmower can do all three modes of mowing. However, it only comes is ready to mulch or bag your clippings. The discharge set up is an additional accessory. In most cases people will not need the discharge which is why I believe they went this route on this particular mower.

Cutting Area

Black & Decker rates this lawnmower to be able to cut a 1/3 acre lot. I would say that possibly is the case if you keep up with your mowing on a regular basis. If you have let your lawn get too long or it has a lot of obstacles and takes extra time you may not finish before the battery runs down to much.

With cordless electric lawn mowers it is important to mow your yard regularly so as to make the battery last longer or at least long enough to complete the job. Tough, tall, grass burns up battery power much quicker than just trimming your lawn which is what you should be doing anyway. If you tend to let your yard go more than just occasionally I would seriously consider using a corded electric lawn mower that way you have the power when you need it and it does not run out.- (Return to Top)

Wheel Size – Height Adjustment

Black & Decker CM1836 wheel adjust

With this being a 36 V medium-sized lawnmower the wheels are a little bit larger than many of the small models. Cool little bit larger wheels make it easier to push and can contend with the extra weight of a cordless lawnmower. The wheels in the front or 7 inches. In the back they are 8 inches.

Black & Decker has fitted this lawnmower with the one lever height adjustment. This is one of the features that people really like on this mower. The height adjustments go from one and a half inches to 3 1/2 inches.

In this section of my reviews I generally state that you need some sort of eye protection, safety glasses or sunglasses, some leather work gloves and possibly ear protection. Do not use this or any other lawnmower without eye protection and closed shoes or boots. Both the work gloves or the hearing protection are your call.

Personally I like the ear plugs that have the headband attached and I don’t just mean a string type I mean a flexible band. The flexible headband helps keep them in your ears and really does block the sound efficiently.

Dimensions and Weight

CM1836 compact storage

The CM 1836 has a working weight of 64 pounds. This is not the lightest mower but that is not extremely heavy either for a cordless electric lawn mower. It is not self-propelled so if you have a very steep yard you may want to look at the Black & Decker SPCM1936, which is a self-propelled model.

What Comes in the Box

If you buy the CM 1836 you will get the cordless electric lawn mower, the 36 V charger, the rear bag assembly, the mulching plug, the safety key and the manual. There is no separate battery because on this model the battery is integrated into the mower. It does not remove.

Because this battery is not removable it is important that you follow the instructions for keeping it charged over winter and that you charge it after use each time. By following these instructions people have had 3, 4 and even 5 or more years of use out of this lawnmower. I would say that three or four years would be good. If you can get more than that it would just be a bonus and show that you took proper care of the battery.- (Return to Top)

Shipping Restrictions

This lawnmower does have some shipping restrictions meaning that it can only be shipped within the United States at this time. It also will ship separately from any other items in your order but you won’t incur additional charges.


Black & Decker gives this lawnmower a two-year warranty and a lifetime deck warranty.

Pros and Cons

Black and Decker CM1836 prosPros: With this lawnmower there are some pros that not all cordless electric lawn mowers have. Versus go over the ones that they all share. With any electric lawnmower you have the benefits of no gasoline, no oil, no tuneups, he won’t smell like an exhaust pipe when you’re done mowing and there is no pull cord.

Specific to this model is the fact that it has a long track record and is still getting great reviews, it can be stored vertically, has a lifetime warranty on the deck, the bag is large enough to not have to empty it continuously and it’s just a solid built mower.

BD CM1836 consCons: As far as the cons with this mower I would say probably the largest drawback with it is the fact that the battery is integrated. Now this won’t be an issue if you take good care of your battery and actually follow the instructions. That really is its largest drawback but it isn’t enough to say it’s not a good purchase. It is a little bit heavier than some of the other cordless lawn mowers but that is only a slight drawback. Mr. drawback is even a little less of a concern and that is the fact that it’s kind of dig for only being an 18 inch cutting deck.

CM1836 Reviews & Consumer Ratings

As stated above most of the reviews are now positive on this lawnmower and there are very few that are negative. Earlier on or more negative ones when they had the first edition but since they’ve made a few small changes those items have been generally taken care of. Most of the reviews read something like this:
“… very convenient machine; no messing with gas and oil. It is easy to maintain and operate …”
“… the CM1836 has plenty of charge to complete my 5000 ft.² yard …”
“… for the average suburban lawn today the CM 1836 is almost perfect …”
“… I love this lawnmower it’s so easy to start …”

B and D CM1836 reviews

“… Overall this lawnmower has gotten great reviews but occasionally there are some that have issues with the height adjustment. This does not seem to be a frequent problem and was more frequent in the previous version but it has been cropping up here and there. Other than that for a medium-sized yard with someone that takes care of their equipment this should be a good choice….”

Consumer Rating: 4.1

My Conclusion

bd cm1836 Review Conclusion In this section of my reviews I talk about how I would consider this lawnmower. For me I like to have a removable battery. Since this lawnmower does not offer that option I will knock the rating down a notch. I do think it is a good lawnmower but it would probably not be one that I personally would buy just because if I have a larger yard or even a medium yard I’m probably leaning more toward a 19 or 20 inch mower and if I had a smaller yard I would go with a 16 inch. With that being said it’s a good mower and I don’t think you would go wrong with it but it wouldn’t be one I will buy. Remember, I am only doing reviews on mowers that are 3 1/2 stars or better. Most of the ones I review are 4 stars and better. So I’m not really talking about any losers unless they happen to be very popular, not too likely. I like the Black & Decker CM1836 it just would not be one for my particular situation.- (Return to Top)
