Lawn Boy 10640 20-Inch 6.75-Gross-Torque Briggs & Stratton Gas-Powered Push Lawn Mower – Review

Most reviewers agreed and were impressed with the good performance of this quiet, relatively lightweight (compared to others they had owned) push lawn mower with some saying that it was the best one they had ever owned. People said it is easy to maneuver and maintain. Most commented on the fact that it’s performance was not hindered in tall or thick grass. People were saying that this mower has a smooth quiet engine and nearly everyone was agreed that the Briggs and Stratton engine is a big plus for this mower….

Although a few parts are updated the core of this engine is pretty much the same as the engines the company has been making for decades (definitely a top quality engine).One reviewer said that a properly maintained Briggs and Stratton engine can easily be reliable for many years and it will outlast nearly all electric lawn mowers in it's class.

The same man said he worked with his parents in their landscaping business while growing up and in his opinion as a residential mower this one is a great deal for your money. He mentioned also that the steel cage for the bag locks easily and securely into steel brackets at the bottom of the handlebars.

The overall deck shape is conducive to good air circulation and channeling of cut material into the bag although almost all reviewers stated that the bag is too small and the area channeling the grass into the bag is only about 3″ x 5″ saying that as a mulching mower it can’t be beat but they were not impressed with the bagging capability.

You can ask for a side chute which they will send you free after you register the mower. There is a box to click on when you register and also a form that comes with the mower to fill out and send inl. Most people do not want the side chute which is why they do not include it in the beginning.

Many were happy with the fact that the Lawn Boy 10640 20-Inch 6.75-Gross-Torque Briggs & Stratton Gas-Powered Push Lawn Mower deck was made of steel and not plastic as so many of the newer mowers are these days which does add somewhat to the weight but is a good trade off. People said the handle height adjustment worked well. There were some who thought the handle should be padded and some people padded their own while others purchased the padding.

One owner had these this to say

“It’s relatively quiet, starts easily, and holds level RPM through any kind of cutting resistance. It’s a bit heavier than others, but that’s good for exercise and I suppose the weight is indicative of the higher quality of the components. The only problem was slight shipping damage that required me to pull out some pliers and bend the wheel-height locking mechanisms back into place.”

Another reviewer said this

“I have had this mower through 2 summers now. I wanted a good mulching mower that was not self-propelled. Just went outside and started this thing up for its third summer and it still runs like a champ.
Probably the only thing i would change is the handle joint connection. I have to fit it in a small shed and need to fold the handle down every time, and it takes a couple minutes to work the bolts/connectors to the point where i can fold it down.” .

The most common complaint we found was the fact that the packaging was not good enough. Several people stated that the packaging was damaged and that they received their mower with damage to the rear height adjusters (sometimes a little and other time more than a little.) People needed to use pliers to pry them back into place.

One man said it like this:
Quote “The packaging which is flimsy and has no handles to grasp. The delivery guy couldn’t hold onto it. It was obvious the package was dropped several times causing damage to the rear height adjusters and put the right rear wheel out of alignment. The damage was repaired with pliers and a crowbar. In summary excellent mower rotten packaging.”

Still others complained that the motor oil in the package was punctured and that oil had leaked all over everything and was a big mess.

One man obviously did receive a lemon though (which can of course happen with any purchase) and even though he added oil and gas as instructed the lawn mower threw a rod after running ran for only about two minutes. Bad customer service and local dealers would not take it apart as they said the warranty would not cover it because it was not purchased from them. He said he contacted Lawnboy and even offered to send pictures they still would not take his name and give him a claim number and of course the fact that he himself took the engine apart made the warranty of no use to him.

Most reviews were very positive 4 and 5 star ratings for the Lawn Boy 10640 20-Inch 6.75-Gross-Torque Briggs & Stratton Gas-Powered Push Lawn Mower and the biggest problem people had was the fact that the packaging is not sufficient to keep the mower safe during shipping and it is possible that sometimes parts can get damaged especially the parts mentioned above.
