The lawnmower is reasonably priced without compromising on features and quality. Most of the cost is for the powerful engine that has been supplied by a company that is trusted around the world. The 159cc OHV engine powered by Briggs and Stratton is very durable and reliable.

This Yard Machines lawn mower is perfectly suitable for yards that are either small or medium sized. Furthermore, the lawn mower allows the user to adjust the height with two adjustment levers, so you can get the result just the way you like it.

Key Features

Powerful Engine

If you were having second thoughts about the lawn mower, the biggest convincing factor is the amazingly powerful engine manufactured by Briggs and Stratton.

If you do not know, Briggs and Stratton is one of the best companies in terms of engine manufacturing. Its engines have had a reputation of being extremely reliable, so if its engine is being used in the Yard Machines 159cc, you can rest assured that the chances of the lawn mower dying anytime soon are pretty much nonexistent. This feature has, in fact, become the selling point of the lawn mower.


During the mulching mode, the side discharge is not open, and the mower would repeatedly cut the clippings until they are very small, which can easily settle in the lawn and decompose. The advantage of this mode is that due to the grass settling back in the lawn and decomposing, the yard does not need as much fertilizer compared to if you were using an ordinary lawn mower without the mulching mode.

One thing to remember is that when using this mode, do not cut more than one-third of the grass length and also avoid cutting wet grass. Also, make sure you are not going too fast with the mower. This is because if you are not careful, the clippings would spread around in the yard instead of decomposing and you will have to do more works cleaning up your lawn.


The bagging mode is pretty useful for a lot of people. In this mode, instead of spreading the clippings and leaving it to decompose, the clippings are collected in a bag or removable catcher. What people like the most about this mode is they find that the lawn seems extremely clean and tidy because the lawn mower essentially works both as a cutter and as a vacuum. This means that it can suck in all the unwanted leaves lying around as well as the sand and debris. However, the catcher needs to be cleaned frequently in order to ensure that the lawn mower performs at its best every time.

Side Discharge

In the side discharge mode, the mower has the capability of discharging all the clipping on one side of the mower. This mode is preferred if the grass is very tall as it keeps the mower unclogged and it can quickly remove the clippings from the deck. Unlike the bagging and mulch mode though, the clippings from this mode are slightly bigger and more visible.

Smooth Turning Wheels and Adjustment Levers

The 8” by 8” smooth turning wheel might be one of the best features of the lawnmower. Most people find it difficult to control a lawn mower because of the unavailability of rear wheels that can help them navigate the machine on hills or obstacle-ridden paths. However, with this lawn mower, you can easily move around and make sharp turns because of the high wheels that make it easier to push this mower around.

The lawnmower also has adjustment levers that can adjust the height of the machine like how the users prefer.
