gas/ oil

when you take this out of the box and its ready for charging, do you have to have the gas/oil in before plugging the mower into the outlet???
Asked by: Anonymous
No, you would not "have" to have the oil added. But I would suggest you did. Just in case you get trigger happy and try to start it as soon as it is charged. I waited until after fully charging to add the gas.

Is the self propelled speed adjustable or is it just "GO" !??

Asked by: Anonymous
If you pull the drive bail all the way up to the handle, it is go and go fast. However, you can slowly release the drive bail until you get a comfortable walking speed.

fuse

when you first buy the mower [Elect start] is the fuse already installed??
Asked by: Anonymous
Yes, all you have to do is plug in the charger. Very simple connection. Let it charge and away you go. You can use it immediately with the pull cord, very easy to pull and starts withing two pulls.

20 in. Briggs & Stratton Electric Start Walk Behind Gas Self Propelled Mower is rated 4.2 out of 5 by 86.
Rated 5 out of 5 by from A Lawn Boy That Lives Up To It's Name This mower couldn't have been easier to go from box to yard. Remove the mower from the box, flip the handle back and use the two bolts with hand cranks to attach it to the mower. Fill it with ethanol free gas, charge the included battery with the included charger and pour the 20oz bottle of Lawn Boy 30wt oil into the crankcase and you're ready to go. No running cables, no putting wheels on, nothing but those two bolts for the handle. Whether using the electric start (which is really fun) or the pull start, the Briggs & Stratton 190cc motor started up right away. It's about the average volume of any regular mower from the engine, but the extra weight of the battery on the deck and the self propelled gearbox minimize the deck vibration so it ends up being a bit quieter than a regular push mower. It comes with a bag if you want to collect clippings and if not, you leave the rear flap down and let it mulch the grass. Attachment of the bag is quick and simple, no tools needed. If you want a discharge chute instead (it does not come in the box), you send in the included card and you'll be sent the chute at no charge. I had no issues with the self propelled mechanism at all. Lift the lever below the handle, which has a low tension so your thumbs don't get tired and off you go. I much prefer this rear wheel drive as it doesn't slip when you hit bumps and ruts in the yard like a front wheel drive does. I can easily recommend this to anyone that may have physical issues pushing a regular mower or especially for anyone to use on hilly yards or fields. I have a 1/4 acre lot and it is just right. I think you could go up to a half acre with a self propelled mower like this before you'd want to look at a rider. Aside from the fun electric start the best feature is the warranty from LawnBoy. 2 year warranty on the entire mower itself and a three year starting warranty on the engine (if it doesn't start in one or two pulls, they'll fix it free). That gives you confidence in this mower for years to come.

Rated 5 out of 5 by from Sturdy engine, nice self propel mechanism I'm pretty familiar with Briggs and Stratton based mowers. I haven't had to buy many since they are bulletproof! With my mowers and my family members' mowers, it was always something else like a rusted out deck that ultimately caused replacement. So with that in mind, I am confident this mower will give many years of trouble free service from the engine. The B&S engine starts easy as advertised. I forgot to charge the battery on my first mow day this year, so I had to use the pull cord. Extremely easy! The next week I tried the electric start, and it was fun. This is luxury! I think this is the perfect mower for someone without a lot of strength but still wants to do their own grass. Combine the electric start with the self propel, and you have an extremely easy mower to use. I mow a lot. In the South, I get at least 40 mow days in per year. As mentioned above, I've never had a B&S engine issue, even though they've surpassed 500 hours of usage over a lifetime. With that much mowing, I'm grateful for the self propel. The propel design works well. It is rear wheel drive. You want that. The last time I tried a friend's self propel, it was front wheel drive. That doesn't work too well since you pivot the back on turns. This propel has a clutch/transmission that also allows variable speed. Very important! You pull the bar a little, and it creeps. Go all the way, and it flies. It also can deal with some stalling. Adjustments for the wheels are pretty easy. I have two types of grass, so I change adjustment on the fronts often. The large levers adjust easily. I found the mulching to work pretty well on my first mow of the spring grass. Switching between mulch and bagging is easy. Just flip up the door and attach the bag. See photo. My last mower had a "door plug" that was easily lost. This is a better design. No assembly required. You just have to add oil and move back and secure the handle. See the photo of the mower in the box. I do wish the handle folded easier. There are large knobs to turn and secure the handle. This works fine, however there are some other designs out there that don't require all the knob turning. It isn't a huge deal though. The mower has some heft to it. The battery adds weight too. This isn't a problem if you use the self propel, so no problem there. This mower starts so easily without the electric ignition that I'm seriously thinking of removing it to lighten things up. One last tip: I found the top speed to be slightly too fast for me. You can either relax the control to slow down, or adjust the cable. I backed off the cable adjustment by 1mm to slow it down slightly. There are instructions in the manual for adjusting the propel cable, but they assume you will set it to max. If you want a bit less than max, just back it off very slightly. Every millimeter is very significant for the speed control. Most users would never have to do this. I only mention it if you are interested.

Rated 4 out of 5 by from Love the electric ignition! Since I have neither had a self-propelled or an electric ignition when it comes to a walk-behind push mower...well, all I can say is why did I wait so long?! The process of just turning a key vs. a pull start is such a wonderful feature! The engine has great power and the mower, itself does a good job at mulching as well as mowing. Assembly was a breeze, you simply tighten the handle and plug in the battery unit and you are good to go. The size of the mower is good & it's easy to handle. You do, however have to mail in a card if you want the side-discharge shute, which I would have preferred to just come with the mower...but all in all, It's a good little mower :)

Rated 4 out of 5 by from Great Features Packaging: The mower arrived in a large but manageable box. Everything inside was packed securely and intuitively. Assembly: The mower arrives almost entirely assembled. Unpacking, assembly & adjustments in total will take at most 10-15 minutes. Oil is included (and appreciated!) and the battery for the electric start charges up overnight. The front wheels are adjustable, but unfortunately, the mechanism with which you adjust them is plastic. The adjustment lever was bent on one of my front wheels upon arrival & as such, would not hold the wheel in place. It would at first, but then I’d hit a bump at it would fall back to the lowest setting. I rarely if ever adjust the wheel height, so instead of fooling with a replacement part, I’ve remedied the problem by drilling a hole through the plastic piece and securing it to the mower body with a bolt and lock nut. However, this seems like too important of an element to construct out of plastic – I wish they’d rethink that design aspect a little and perhaps create a spring-loaded metal piece or something. Electric Start: The electric start feature is fantastic. The mower fired right up after 24 hours of charging. I stopped and started it several times with no problems. It also starts off the pull rope, so if you’re battery isn’t charged, you have a backup option. With any luck though, I’ll never start a mower with a pull-rope again! Self-Propelled Feature: The self propelled feature is really nice. It takes a minute or two to get the hang of it, but after that it feels quite natural. I was able to keep up at full speed without issue, though it is a good pace. My grass was still a little damp from a rain 36 hours earlier, and the wheels spun some on inclines, but I’m hoping in the summer months when it’s hotter and dryer, that will be less of an issue. The front wheels will need to be adjusted – if you’re on flat ground & you’ve engaged the self propel feature, and it’s not moving, odds are your front wheels are too low. Rear Discharge: Please note that this a REAR discharge mower. All of my previous mowers have discharged out the side, so this threw me at first (actually, it threw me for several minutes – read on). The bag for grass collection is included and it’s very simple to install & remove. And while I risk sounding like an idiot (again, always had side discharge mowers before!), surely I’m not the ONLY person out there who have/will make this mistake: at first glance in dim garage light, it appears that there is a rectangular hole in the middle of the black plastic portion on the back of the mower, through which one MIGHT assume that the grass would exit the mower and into the bag that fits down over it. WRONG. That is, in fact, a HANDLE, not a hole – you must lift that whole plastic area forward & secure it down with the grass collection bag in order for it to discharge. I’m ashamed to admit I made it two full laps before realizing that there was nothing going into the bag. Once I re-installed the bag properly, it did an excellent job of catching the grass & removing it to empty was simple enough. There is also a side discharge attachment that they will mail to you for free once you register your product. The good news is it’s free, the bad news is it doesn’t come in the box, you have to send off for it. I haven’t received mine yet, but I expect to use it quite a bit as I don’t always bag my grass. It would have been nicer if it had come with the mower, but since they’ll send it for free, I won’t fuss too much. Overall: Great set of features on this mower – electric start and self propelled functions are top notch. The mower fired right up & produced a nice even cut. The rear bagging setup makes it very easy to empty the clippings. The side discharge attachment is available for free for those interested. The only negative is the plastic wheel adjustment. I am certain mine being bent was a fluke, but it still makes me wonder about how they’ll hold up long term. As there are plenty of fairly easy workarounds in the event they do fail, I won’t hesitate to recommend this lawn mower. The pros definitely outweigh the cons.

Rated 5 out of 5 by from Awesome use for a single woman!!!!!!!!!!!!!! I have been through every lawn mower....orig. pull start w/ gas. I do not have strength or arm length to pull the cord. Then I bought an electric mower , where you plug it in and drag cumbersome cord around the yard. (almost strangled myself many times) This mower is by far the best!! It was my last chance before I hired a lawn services ( I was very frustrated). Not any more.....with a few adjustments to the self propel ( It was going to fast for me) It is perfect now....lawn work done in a jiffy!!! Can't wait to mow the lawn again! I love the key start!!!! Price def worth it!!!! Shipped fast to store..I picked up and was in excellent condition in box!

Rated 3 out of 5 by from Mulching Challenged After reading several positive reviews for the Lawn Boy Model 10634 mower I purchased it from the local HD store. On the positive side this mower started easily, ran smoothly and was fairly light to use. A lack of side discharge chute was a little unsettling however based on the positive comments on the mulching ability on this mower I believed it wasn't necessary. Cutting(mulching) the grass for the first time a trail of grass followed me much to my displeasure. I thought that perhaps the grass being a bit wet caused this. A second cut yielded the same results so I told myself I cut the grass too short. The 3rd and 4th cuts a few days apart yielded the same results as cut 1 and 2. Returned to HD and purchased a Honda. If you plan on bagging your grass clippings that this mower is for you, however if you like to mulch your grass clipping than this mower is not up to the task.

Rated 5 out of 5 by from Awesome Mower It takes no more than 15 minutes to attach the handle and add engine oil. That's it for assembly. I charged the battery overnight, added some gas, gave the rope a half hearted pull and it started! First pull. My Bermuda grass is dormant so I headed to the neighbors yard and cut her grass. It handled the tall fescue well. Next I tried the electric start feature. Fantastic. The engine is fairly quiet. There is no choke or primer bulb to deal with. Just a flip of the switch. The rear bag attachment installs and removes easily and it has a nice large throat that makes for easy emptying. When you engage the self porpelled lever it takes off at a pretty brisk pace and the rear wheel drive is much better than front wheel drive when going uphill as the wheels spin on front wheel mowers I've used. I have never seen a mower start as easily as this one. Flip the switch or give it one pull and it starts every time. Very, very nice mower.

Rated 4 out of 5 by from Excellent mower with one major issue Received the mower well boxed. Took about 20 minutes to unpack and assemble the handles. Definitely had to charge battery for 24 hours. Not 20, 21 or anything short of 24 hours. Then the light turned green indicating full charge. After battery was fully charged, oil and gas added mower started with first turn of the key. Excellent. And on first pull with recoil starter. Excellent. Mower has plenty of power and really gets off to a flying start. Be prepared to almost run to keep up, or slowly release the drive bail until you get a comfortable walking speed. Mowers climbs my hill (about 30 degree grade up) without hesitation. Mulching is great. Major issue. As others have stated, the rear wheel adjustments are not easy to adjust. Matter of fact, I had to use a hammer to hammer the third adjustment tab outwards so it would catch on the adjustment lever. This should be something Lawn Boy could correct. Too many write ups about height adjustments issue right out of the box. However, I do recommend this mower for someone looking for a great walk behind self propelled mower, and especially one with electric start. Great lightweight mower.
