Smaller suburban lawns typically don’t need the overkill of a big, heavy gasoline lawn mower or even the added cost of a battery-powered model. Sometimes all you need to maintain a modest-sized suburban lawn is a straightforward, yet well-engineered corded electric lawn mower like the Greenworks MO09B01.

The Greenworks MO09B01can be connected to any standard outdoor electric outlet via a 50-foot extension cord. The connection in the handle holds it firmly in place without having to worry about it coming easily unplugged in the middle of a mowing session.

The metal cutting blade housed under the Greenworks MO09B01’s 21-inch diameter cutting deck is powered by a 9 Amp electric motor. The deck itself can be adjusted through five different cutting height settings from as low as 5/8-inch to as high as 2-5/8-Inches.

The Greenworks MO09B01 was also designed with thatch management in mind. You can use it as a mulching mower or a bagging lawn mower. This virtually eliminates the presence of choking thatch from the upper layers of your turf. At the same time, it can also provide vital nitrogen to your lawn or your compost pile.

Key Features

  • 9 Amp electric motor
  • 14-inch diameter cutting deck
  • 5 cutting deck height positions
  • Cuts from 5/8-inch to 2-5/8-Inch
  • 2-in1 bagger or mulching mower


The 9 Amp electric motor on the Greenworks MO09B01 delivers robust enough power to the cutting blade of the 14-inch deck to make short work of most suburban lawns. This corded electric mower only weighs in at 36-pounds, so it’s very easy to move around the yard without the need for a self-propulsion system.

Of course, the Greenworks MO09B01 shares a common minor complaint with a lot of corded electric lawn mowers, in that a standard household extension cord limits its effective range to 50-feet or less from the nearest outlet. When you go beyond 50-feet the extension cord struggled to deliver the necessary power to optimize the performance of the 9 Amp electric motor. If you do need to mow at more than 50-feet, you may want to invest in a commercial-grade extension cord that is engineered to power tools and devices at 100 feet or more from the nearest outlet.

Ease Of Use

As a corded electric lawn mower the Greenworks MO09B01 is very easy to use. You literally just need to press a button to activate it. Then when you are done, it is light enough to store vertically. If you have strong standalone garage shelves or robust wall-hanging hooks, you might even be able to store it off the floor.

Of course, you face the same cord challenges that you find with all corded electric lawn mowers. Though all you have to worry about is keeping the cord tangles at bay, as the connection on the lawn mower itself is secure enough that it won’t easily pull out from a small, accidental tug.

Special Features

The 2-in-1 versatility of the Greenworks MO09B01 is arguably its most special feature. When fully assembled it is a mulching corded electric lawn mower. Though you can just as easily convert it over to divert the harvested grass clipping through the rear discharge port to the bagger, which is included in the original purchase.

Cut Quality & Options

Being able to adjust the Greenworks MO09B01 from as low as 5/8-inch to as high as 2 5/8-inches lets you manicure your lawn to the height that works best for the prevailing weather pattern. If your lawn is growing fast, the lower end of the five cutting deck settings will let you stay ahead of the grass for a neatly trimmed look. If the local weather turns dry for a week or two, you can start to adjust the height of the deck up. This will have the effect of helping to shade the upper turf layers to preserve a little bit of the essential soil moisture.

The 2-in-1 versatility of the Greenworks MO09B01 is also very handy. When you leave it as a mulching mower, the tiny bits of harvested grass clippings it leaves behind will decompose quickly under normal weather conditions. This prevents them from drying out into thatch, which can gradually start to choke out your turf, making it hard for your lawn to adequately absorb water from rain or lawn sprinklers. The decomposing grass clippings can also help feed trace amounts of nitrogen back to your lawn to help organically boost natural growth.

If the local weather pattern has been overly dry, or you simply want to make other use of the nitrogen-rich grass clippings, you simply need to set up the rear discharge chute and attach the bagger. You can then bring the harvested grass clippings to your compost pile or your garden. The mulching effect creates tiny blades that will give your compost pile a quick boost of organic nitrogen.


As a corded electric lawn mower, the Greenworks MO09B01 requires very little maintenance. Just make sure to store it indoors when not in use and do your best to keep the extension cord organized.

The metal of the cutting blade on the Greenworks MO09B01 is somewhat thin. It’s probably better to purchase replacement blades than to try to manually sharpen the original cutting blade when it dulls. Thankfully an extra cutting blade is included in the purchase!

Safety Features

The Greenworks MO09B01 comes with all the standard hand control safety features you expect to find in a quality corded electric lawn mower. The electrical connection also does a good job of holding the extension cord in place.

If you do happen to encounter an unforeseen obstacle you can always stop the electric motor with a single press of a button. When you are ready to cut again, you can start it just as easily, without the labor that often comes with restarting a gasoline lawn mower.


The Greenworks MO09B01 is a very cost-effective corded electric lawn mower for maintaining a small to modest-sized suburban lawn. You certainly don’t have to deal with the fuel, oil, and spark plug issues endemic in gasoline lawn mowers.

The fact that you can set it up as a mulching or a bagging lawn mower also helps you maintain your turf of your compost pile as you see fit. It might even save you money on seasonal aeration and fertilizing costs.
