One of the best mowers I have ever used.
4 Stars
One of the best mowers I have ever used.
Okay so this review is for the 20-in greenworks twin Force 40 v electric lawn mower with the 4 amp hour battery and 2 amp hour battery. I was comparing this to an ego which my parents had purchased years ago and swear by it and I could not justify the price. So I decided to take a chance on this one having it been a little bit cheaper than the ego. some of the reviews are mixed and some of them are very detailed and there's a few that are basically a one-star rating and after weeding out the pros and cons of each review I decided to go with this so. If you purchase this from Amazon this will come on a truck it is a rather big box but it weighs from what I was able to decipher less than 50 lb. The box itself has handles in the side which are very flimsy and very weak I do not recommend that you lift the box using those handles as it will tear the box apart. Opening the box I was completely surprised as this unit was much lighter than my gas powered mower it contains the mower handle and a package with the charger and two batteries. This is very easy to assemble and requires no tools. The four amp hour battery took approximately 1 hour to charge the 2 amp hour battery took approximately 30 minutes or so to charge. So that being said, I noticed when I removed the 4 amp hour battery from the charger it was quite hot, this is not a big concern as it does cool down quite quickly and is comparable to any other 40 volt battery. The charger design is quite simple and is almost identical to all of the other rechargeable batteries it does have a lock so that when you insert the battery into the charger you must lock it in place you will hear click when it is locked to remove the battery you simply put on the lock button on the battery and slide it in reverse of how you inserted it. One thing to know is that read the instruction manual! With all other mowers you will pull back on the safety handle and then start the machine with this specific machine you hold in the start button and pull back on the lever once the machine is started you can let go of the start button. If you try it any other way the machine will not start. This is how I was able to narrow down a lot of the negative reviews that said that it doesn't work. People did not read the instruction manual. At first glance on the underside the blades seem extremely small but are quite sharp. I'm not sure if they are going to be difficult to find so I would recommend getting a spare set of blades to accompany the machine. And in one of the pictures that accompanies this review it shows the two blades almost rubbing together there is a quarter of an inch space between the blades so as long as your shaft doesn't get bent you should not have any problems with this but you will need to get the exact size blades for replacement to keep this quarter inch gap. Again the batteries are standard batteries and seem to be pretty decent. It does come with a 4 amp hour and a 2 amp hour battery and will automatically switch over when one battery is depleted. Although I do recommend placing one on a charge and the other in the machine therefore when one battery goes dead you will have a spare battery that is fully charged. It does have a great feature with one handle raising and lowering the height of the wheels. This is so simple and very easy to do unlike classic mowers which you usually had to do each individual wheel and sometimes struggled with it. This actually does all four wheels at once. Now when I tried out this for the first time in my yard I was very skeptical I didn't think it was going to do a good job but I decided to give it a go anyway instead of sending it back at first look at the undercarriage it looked very cheap and not well made but again I decided to take a chance on it. This cut through wet morning grass like a hot knife through butter I am so impressed with this mower it actually cut fantastic shaved about 15 minutes off of my normal cut time and was just light as a feather going through the grass. It was not loud at all in fact my dog usually runs from loud noises and he didn't even budge. To be honest my shop-vac is 10 times louder than this is. I will post a decibel rating as soon as I have another person to hold the machine in the on position. Once I was done with my lawn which is rather small less than a quarter acre. I noticed that the 4 amp hour battery had only gone down one bar. I had been out there using it for approximately 15 to 20 minutes in wet, thick grass. Now to get an idea of runtime I am guesstimating that in ideal conditions normal grass height, not foot long weeds, and dryer grass not wet. This should get approximately 45 minutes to 50 minutes of use on one 4 amp hour battery. What I do recommend is that if you are using this on a larger lawn I would highly suggest getting at least one more 4 amp hour battery. Anything more than one acre of land I will not recommend this for as it would be too much for this mower I believe to successfully handle. But for standard lawns approximately a half an acre or less I really do believe that this mower would be fantastic for you. I like to keep my lawn a little bit longer than most lawns in my neighborhood so that it will remain nice lush and green in the hotter months. Just so it will prevent drying out . Okay now on to the pros and cons.Pros1. Is very lightweight2. Mulches better than most3 bag has a indicator indicating when it is full and when you should empty it.4. Batteries seem to last a good amount of time and has dual batteries with an automatic switch over when one battery is depleted.5 wheel height adjustment does all four wheels at once and is very easy to use.6. Has quick lock release clamps so that you can quickly and easily fold up The handle for quick storage.7. 10-in wheels in the rear8. Batteries are cross-compatible with most all green works 40 volt tools.9. Comes with two batteries and charger10. Cheaper price than most electric mowers on the market.Cons1 cost to replace the battery is on the expensive side right now approximately $150.2 blades seem rather small and could be very difficult to find replacements for at a later date.3 ABS plastic deck seems rather lightweight and could present problems if you were to accidentally run over larger sticks or larger debris and may not hold up.4 quick release clamps if over tightened could potentially break if you're not careful and don't understand how to adjust it.5. Documentation is not very well written and does require a little bit of common sense to read between the lines. It does not indicate how long the batteries take to charge.My overall opinion of this mower is that it is definitely well worth the investment and is comparable to some of the big name electric mowers on the market currently.I will update this review from time to time as months go on. The only reason I did not get this a full five-star review is that there is always room for improvement for example instead of having an ABS deck maybe make a tempered aluminum deck.Update. The decibel level from standing directly behind the machine is 72.2Basically, the equivalent of a shower or toilet flush. Slightly less than a vacuum cleaner.
