The Yard Machines 159cc 21-Inch Self-Propelled Mower has what it takes to give its operator a stress-free and even fun mowing experience. The best thing about this lawn mower is the fact that it is self-propelled.

This means that there is a need for minimal intervention only on the part of the operator and that lawn mower can basically do the mowing chore without the push or maneuvering of the operator. Also, with the self-propelled feature of this lawn mower, the operator does not need to exert too much effort in directing the machine across the yard.

It should also be noted that the lawn mower boasts of a powerful engine that makes the product a perfect tool for heavy duty mowing. Even with hard and thick grass in the yard, this lawn mower can effectively cut the grass without any difficulty.

Moreover, the powerful engine of the lawn mower makes it easy for the device to go cover a small to medium sized area. So having this lawn mower around makes it convenient for the owner to put the machine out to maintain even large back yards.

Also, aside from the self-propelled capacity of the lawn mower, the mobility of the machine is also improved with some of its additional features. For example, the lawn mower has front wheel drive. It also has a single forward speed that makes it a self-propelled lawn mower.

The light weight of the lawn mower, as well as the big wheels, make it easy for the machine to traverse different yard terrains. In addition, the side discharge and mulching capacity of this lawn mower give the operator several options on how to go about with the disposal of the grass clippings.

Most importantly, the cutting capacity of this lawn mower should not be left out. The cutting width of the blade itself is wide enough at 21 inches. There is no discomfort in using the lawn mower for a long time because it has a dual-lever height adjustment that makes it easy on the back of the operator.

The same adjustable level also makes sure that the grass is being cut at the correct height. If all those features are not enough to impress an interested lawn mower buyer, then the 2-year limited warranty of the product will probably drive the nail on its head and seal the deal.


One should know that although the Yard Machines 159cc 21-Inch Self-Propelled Mower has praise-worthy features, it also has its fair share of disadvantages. There are some issues with the packaging of the lawn mower where there have been reports that some parts are missing.

Another issue with the lawn mower is its blade which only happens to be 21 inches. It would have been better if the cutting width is wider, especially so when the lawn mower is able to cover small to medium sized yards.

To add, although the lawn mower has a side discharge and mulching features, it does not have a collector bag to which the grass clippings could be easily stored.

Nor can a collector bag be attached to the lawn mower. Also, there is the issue with the size of the lawn mower’s chute.The chute is a little bit small so if there are damp and thick grasses, the chute can easily get clogged.

Finally, the fact that the lawn mower is gas powered has its accompanying set of drawbacks. First, the oil and gas can be a little expensive at times. Second, the lawn mower requires regular maintenance in order to keep it in tip top shape.

And third, using the lawn mower would lead to the production of carbon monoxide and carbon dioxide, both of which are harmful to the atmosphere and can add to air pollution.


This Self-Propelled Mower may have its drawbacks that interested customers should take note of, but those issues are not enough to make this machine a bad product. In fact, despite the reported issues, Yard Machines 159cc 21-Inch Self-Propelled Mower is generally a high performer and is made of good quality. For a first time user or those who are planning to get a new lawn mower, this is a recommendable product to have.
