GreenWorks 25112 Review – Is 13 Amp 21-Inch Lawn Mower A Good Buy?

GreenWorks 25112 13 Amp 21-Inch Lawn Mower

If you are planning to buy a new electric lawn mower then you should read this GreenWorks 25112 review first. With a 21-inch steel cutting deck, the grass mowing machine is ideal for smaller yards, 1/4 acre or less. Here are some pros and cons, as well as some of the products specifications that you might want to consider:

Power and Performance

The GreenWorks 25112 operates using a 13 amp electric motor. The rated no load speed is 3600±180 RPM. It is a corded electric mower which means an extension cord is required in order to operate this outdoor power equipment. A 50’ (15 m) extension cord should be of 16 AWG, a 100’ (30 m) extension cord shouldbe 14 AWG, and a 150’ (45 m) extension cord should be 12 AWG. The plus point is it produces no exhaust fumes or emissions.

Multi-Function Capability

Multiple options for grass clippings are provided. The 3-in-1 corded lawn mower allows flexibility between rear bagging, side discharge and mulching. It comes with a grass catcher bag. A side discharge chute is also provided that allows you to divert the clippings through the side opening. It can also work as a mulching mower, allowing you to return the organic matter back into the soil. Just insert the mulching plug into the rear discharge opening.

Height Adjustment

You can raise the cutting position to the height best suited for your lawn by moving the height adjustment lever toward the back or toward the front of the mower. Seven cutting height settings are provided. The lowest setting is 1-3/4-Inch and the highest setting is 3 3/4-Inch. During cool months you may want to cut the grass 1 3/4″ to 2″ tall and between 2″ and 3 3/4″ during hot months to reduce the stress on your lawn.


Weighing around 55 lbs (24.8 kg), It is lighter than most gas mowers. It would be easily maneuverable by almost any user. The rear wheels are higher than the front ones (10-Inch vs 7-Inch). Mowers with the same size wheels tend to be easier to maneuver. However, models with larger diameter wheels come in handy when dealing with rough, undulating surfaces. No need to worry about the deck scalping the lawn.

Pros and Cons

GreenWorks 25112 Folds Down Handle

The GreenWorks 25112 commands a respectable 4.5 stars out of 5 on the Amazon ratings. It has received very good feedback from many buyers. Cutting grass with a corded mower means you have to avoid running over the cord. You need to plan ahead a bit. However, this is not terribly difficult.

Despite some minor considerations, many customers have reported that it works as promised. In terms of performance, some of the reviews may put you off. However, based on the customer reviews, it does a nice job cutting grass and mulches very well for an electric lawn mower. Mowing through thick and/or tall grass is not a problem. There may be times when you need to walk slow and give time to the mower to do the job but this is to be expected.

The design and construction have also made a positive impression upon the reviewers. Changing form side discharge, to mulch, to bagging is simple. Positive comments have also been expressed by the reviewers in reference to the one-lever height adjustment. You can raise or lower it with one hand. Further, it folds up for easy and space-saving storage. The GreenWorks 25112 is not a self propel mower but customer feedback suggests that it is easy and light to handle.


The lean, green lawn mowing machine is not perfect. That being said, it seems to have satisfied many of those who purchased it. If you want a quiet, low maintenance lawn mower to maintain a typical suburban lawn, then based on the customer feedback you will be happy with this outdoor power equipment.
