Finding the best PowerSmart lawn mowers with side discharge requires looking at key specifications. We compared 3 models based strictly on the data published on their listings. Our top pick is the PowerSmart 22-Inch Gas Self-Propelled Lawn Mower. It leads because its 22-inch cutting width covers more ground per pass than the other options. This wider deck helps you finish larger yards faster. The guide helps you decide which mower fits your yard size and terrain needs.
Choose drive type for your yard
Select a self-propelled model if your yard has slopes. The top pick offers a 22-inch cutting width and 170cc engine for better traction on inclines. For flat, small yards, a push mower with a 140cc engine is sufficient. This drive type difference determines ease of use on uneven ground.

How to choose the right mower
Match cutting width to yard size
A wider deck covers more ground per pass. The top pick features a 22-inch cutting width, which reduces mowing time for larger lawns. This model trades compact size for broader coverage. Smaller yards may find a 21-inch deck sufficient. A narrower deck is easier to maneuver around tight obstacles. Choose the width that matches your available space and desired efficiency.
Select power type for your needs
All listed models use gas engines. Gas power provides consistent output without charging delays. You do not need to worry about battery capacity or voltage levels with these units. The trade-off involves fuel storage and engine maintenance. If you prefer electric operation, these specific PowerSmart models are not suitable. Gas engines deliver reliable power for standard residential mowing tasks.
Choose drive type for terrain
Self-propelled models assist with movement, reducing physical effort. The best overall pick includes self-propulsion, aiding traction on slopes. The budget option is a push mower, requiring you to walk alongside it. This design works well on flat terrain. If your yard has inclines, self-propulsion prevents fatigue. Push mowers remain lighter and simpler for small, level areas.
Compare engine displacement for power
Engine displacement indicates potential power output. The top pick has a 170cc engine, offering more torque for tough conditions. The other models feature 140cc engines, which are adequate for standard grass. Higher displacement supports wider decks and self-propelled systems. Check this spec if you have thick or wet grass. Smaller engines suffice for light, regular maintenance on healthy lawns.
Check mowing functions for disposal
Side discharge is the primary function here. All models include this feature for grass ejection. Some also offer mulching or bagging options. The best bagging pick includes a bag for clippings. Mulching chops grass for lawn health. Side discharge clears debris quickly. Verify which functions you need for your cleanup routine. Not all models support every disposal method.
Frequently asked questions
Which PowerSmart mower has the widest cutting deck for side discharge?
The PowerSmart 22-Inch Gas Self-Propelled Lawn Mower offers the widest cutting width at 22 inches. This broader deck covers more ground per pass, making it efficient for larger yards. It pairs this width with a 170cc engine and self-propelled drive for better traction on slopes.
Is there a self-propelled option for side discharge mowing?
Yes, two models feature self-propelled drive systems. The top pick is a 22-inch model with a 170cc engine, designed for larger or sloped yards. Another option is a 21-inch self-propelled mower with a 140cc engine, which adds weight for stability on inclines while supporting side discharge.
Which model is best for small, flat yards?
The PowerSmart 21-Inch 140cc Gas Push Mower is ideal for small, flat terrain. It uses a push drive rather than self-propulsion, which keeps the unit compact. Its 21-inch cutting width and steel deck provide a practical solution for smaller lawns where you do not need extra traction.
Does the top pick include bagging for side discharge?
The top pick, the PowerSmart 22-Inch Gas Self-Propelled Lawn Mower, supports 3-in-1 functions including side discharge. It does not explicitly list bagging in its attributes. The third-ranked model is the better choice if you require both bagging and side discharge capabilities for your mowing needs.
What is the engine size of the budget-friendly model?
The best budget option, the PowerSmart 21-Inch 140cc Gas Push Mower, features a 140cc engine. This engine displacement is sufficient for small, flat yards. It pairs with a 21-inch cutting deck to provide reliable performance without the added complexity or weight of a self-propelled drive system.
How heavy is the heaviest PowerSmart side discharge mower?
The heaviest model on the list is the PowerSmart 22-Inch Gas Self-Propelled Lawn Mower, weighing 75 pounds. This weight, combined with its self-propelled drive, aids in maintaining traction on slopes. In comparison, the self-propelled 21-inch model weighs 64 pounds, while the push model has no listed weight.
Can I mulch and side discharge with the same mower?
Yes, several models support mulching alongside side discharge. The 21-inch push mower and the 21-inch self-propelled mower both list mulching as a function. These mowers offer 3-in-1 or 4-in-1 capabilities, allowing you to switch between mulching, bagging, and side discharge depending on your lawn care requirements.
Which mower is best for slopes with side discharge?
The PowerSmart 22-Inch Gas Self-Propelled Lawn Mower is best for slopes due to its 170cc engine and self-propelled drive. The 21-inch self-propelled model is also suitable, as its extra weight aids stability on inclines. Both models provide the traction needed to handle uneven or sloped terrain effectively.
