The Lawn Hog features a 12 Amp motor, which produces plenty of power to cut and mulch even deep, wet grass. The electric motor produces lower noise and emissions levels and eliminates stopping and starting to refill gas tanks or clean dirty filters and spark plugs.
Built-In Adjustable Features to Match Your Lawn
Choose a deck height between 1 1/4 and 3 1/2 inches--all fours wheels raise and lower with the push of a button. Set the length higher if you mow often or keep it tight to give yourself added time between mowing.
A Comfortable Grip That Adapts to You
The specially cushioned grip reduces vibrations that can lead to fatigue while giving you added safety and control. And the handle can be adjusted to the perfect height for you, allowing you to stand upright with arms extended to mow comfortably.
Bag or Fertilize While You Mow
Keep your lawn tidy by gathering clippings in the included bag, which detaches easily for dumping or composting. Keep the bag off to mulch your lawn with the trimmings, providing a natural fertilizer.
Perfect for your small or medium sized lawn, the Lawn Hog will mow within a 100-foot radius of the nearest outlet. The compact size is easy to control for a precise cut, and the handle folds for easy storage when not in use.
The 19-Inch Lawn Hog Electric Mower is covered by a full two-year warranty.

Next, check your extension cord. If you are using a long, flat cord, the wire size is probably too small for this mower. Look for a cylindrical cord that is marked along the cable as 12 AWG. This mower does not require a ground wire, so a two conductor cable will work, but the wire size should not be smaller than 12 gauge (the higher the number, e.g. 16AWG or 18AWG, the smaller the wire). Smaller wire simply cannot carry enough juice to run this motor to rated power, it may damage the motor over time, and it may be a fire hazard (though a properly wired outlet should trip the breaker before the cord gets hot enough to be a hazard).
You will have to invest $50 or $60 dollars in a good, 12 gauge, 100' extension cord, but anything you run on it will work much better than that cheap 16/3 or 18/2 cord you have in the garage now. When shopping for cords, the label "16/3" means that the wire is 16 gauge (too small) and has three wires (hot, neutral, and ground), "12/2" is an ungrounded 12 gauge cord with only two wires, one hot and one neutral. Look for a 12/2 or 12/3 cord, though a 12/3 (grounded) cord will be more versatile for other applications.
Note that Black and Decker does not recommend using a 100' cord with this mower regardless of wire size, but mine works fine with a 100' 12AWG cord off of a 20amp outlet.
For those who want a little more technical explanation, the voltage of a circuit drops as the distance from the source increases. If your outlet is 50' from the breaker box and you have a 100' cord to the 12amp mower motor, using 14 gauge wire you will have a 10.4% voltage drop, meaning the mower motor will only realize 108 VAC rather than the 120 VAC the motor is designed for. Using the same lengths with 12 gauge wire to the outlet and in your extension cord, there is a 6.7% voltage drop (112VAC at the mower motor), which is a bit more than the optimum maximum of 5%, but still tolerable.
The mower has been used on St Augustine grass that has recently received much rainfall. Because of the need to wait between rains until the grass was no longer wet, the lawn got a little longer than desired between mowings, but had a healthy level of moisture when it was mowed. The mower seemed to cut each blade of grass cleanly without evidence of tearing. I noticed a few uncut blades of grass at times necessitating going back over those areas, but this was no different than my prior experience with gasoline mowers. Walking a little slower (probably a little slower than what would be required with a gasoline engine mower) seemed to prevent this from occurring.
The first time I used the mower, I was having a little problem placing the bag on the mower and the flap that has to be lifted to put it in place keep getting hung up. When I looked closely, I noticed the cord coming from the mower was bowing out slightly and that was causing the flap to hang up. I pulled the cord tight to remove the bowing and moved it outward slightly so it no longer interferes with the flap or the bag.
Why I chose a corded electric mower:
1) I don't have a lot of lawn area to mow.
2) I can reach all areas of the lawn using a 100 foot cord.
3) It should have more power than a cordless electric mower and there is no battery to maintain.
4) It is less polluting than a gasoline mower.
5) It is much quieter than a gasoline mower.
6) It is easier to start and stop than a gasoline mower. For me, this is a safety feature that actually offsets the minor risk of having a cord. With a gasoline mower, there is a tendency to want keep it running rather than having to pull the cord to restart it.
7) It is virtually maintenance free.
8) It doesn't require gasoline to be transported to or stored around the home.
There are some minor issues with this mower, but these issues are common to all corded electric lawn tools:
1) The cord can get a little bothersome at times, but it's not really a major issue. When I mentioned looking for a corded electric mower to a local lawn equipment dealer, she mentioned the risk of electrocution from running over the cord. The reality is, while I don't advocate running over the cord, the risk of electrocution from doing so is low. The only time I ever cut a cord, I had became very exhausted while using an electric hedge trimmer. There were lots of sparks, but the double insulation, kept me and the hedge trimmer from harm. Lesson: Never use any tool, especially a power tool, when you are tired.
2) The further you have to get from the outlet with a corded tool the heavier and more unwieldy the extension cord becomes. (Going further out than 100 feet with this mower would require a very heavy 12 gauge cord and the maximum recommended distance is 150 feet.)
3) I have found electric power tools are more sensitive to prolonged usage. While it's working, the moving parts and the electric motor generate heat and heat can be damaging. This is especially true if, for some reason, the load on the tool is greater than usual. Because a corded tool doesn't run out of gas or deplete its power supply, it's easier to keep it running for long stretches at a time, thereby overworking them and decreasing their lifespan. (A battery powered tool will have to be recharged after a period of usage so it's less likely to be overworked.) And, although gas powered tools in general can tolerate longer stretches of use, they should be allowed to cool before being refilled.
