You want the best PowerSmart 170cc lawn mowers that fit your yard needs. This guide compares 6 models based strictly on their published specifications. We analyzed engine displacement, cutting width, drive type, and weight to find the right fit for you.
The PowerSmart 21-Inch 170cc Self-Propelled Gas Mower leads the list. Its 59-pound weight and 21-inch cutting deck make it ideal for small lawns on slopes. Use these spec-based picks to decide which mower handles your terrain and storage constraints.
Choose width based on yard size
All models feature a 170cc engine and self-propelled drive. The main difference is cutting width. You have 21-inch or 22-inch options. A wider deck covers more ground per pass. If you have a larger yard, the 22-inch models reduce mowing time. If you need tighter maneuvering, the 21-inch models fit better. Both sizes offer reliable traction for slopes.

How to choose the right mower
Check your yard size
Select a cutting width that matches your lawn dimensions. All models in this guide offer either 21-inch or 22-inch decks. A 21-inch deck, like the PowerSmart 21-Inch 170cc Self-Propelled Gas Mower, suits smaller yards or tight spaces. A 22-inch deck, found on the PowerSmart 22-Inch Gas Self-Propelled Lawn Mower, covers more ground per pass. Wider decks reduce the number of passes needed. This saves time on larger lawns. Consider your storage space too, as wider decks often require more room when not in use.
Assess slope traction needs
If your yard has slopes, prioritize self-propelled drive types. All models here feature self-propelled systems, but rear-wheel drive offers better traction on uneven terrain. The PowerSmart 21-Inch Rear-Wheel Drive Gas Mower is designed for slopes. Rear-wheel drive pulls the mower forward, reducing effort on inclines. This is crucial for safety and control. Front-wheel drive models exist but are not in this specific list. Ensure the drive type matches your terrain challenges to avoid slipping or struggling during mowing.
Evaluate storage constraints
Measure your storage area before buying. Dimensions vary significantly among these models. The PowerSmart 22-Inch Gas Self-Propelled Lawn Mower measures 59.8 inches in length and weighs 75 pounds. This requires ample garage or shed space. The PowerSmart 21-Inch 170cc Self-Propelled Gas Mower weighs 59 pounds, which is lighter and easier to move. Check height and length specifications carefully. Compact models like the PowerSmart 21-Inch Rear-Wheel Drive Gas Mower may fit tighter spaces. Plan for easy access to your storage location.
Consider discharge options
Look at mowing functions if you have specific debris preferences. Most models offer 3-in-1 capabilities, including mulching, bagging, and side discharge. The PowerSmart 22-Inch Gas Self-Propelled Lawn Mower adds side discharge for quick clearing. Some models, like the PowerSmart 22-Inch 170cc Self-Propelled, offer only 2-in-1 functions. Choose based on whether you want to collect clippings or leave them as mulch. Side discharge helps in tall grass. Ensure the function aligns with your yard maintenance routine and local regulations.
Review included equipment
Check if the package includes additional tools. The PowerSmart 22-Inch 170cc Self-Propelled Gas Mower Kit comes with an edger and brush cutter. This is ideal for comprehensive yard care. Other models are sold as standalone mowers. If you need trimming or edging, the kit saves buying separate units. Verify the included equipment list in the specs. This ensures you get all necessary tools for your yard. Standalone mowers are simpler but require additional purchases for other tasks. Decide if the combo value fits your needs.
Frequently asked questions
Which PowerSmart 170cc mower is best for small lawns on slopes?
The PowerSmart 21-Inch 170cc Self-Propelled Gas Mower is the top choice for this use case. It features a rear-wheel drive system that provides reliable traction on uneven ground. The 21-inch cutting width suits smaller yards, and the 59-pound weight makes it manageable for most users.
Do all these models have self-propelled drive systems?
Yes, every model listed in this guide uses a self-propelled drive type. This means the wheels are powered by the engine, so you only need to guide the mower rather than push it. This feature reduces physical effort, especially when mowing on inclines or thick grass.
What is the difference between the 21-inch and 22-inch cutting widths?
The primary difference is coverage per pass. A 22-inch deck cuts a wider swath than a 21-inch deck, reducing the number of passes needed for larger areas. The 21-inch models are often lighter and more compact, while the 22-inch options offer broader coverage for bigger yards.
Which model includes a trimmer or edger kit?
The PowerSmart 22-Inch 170cc Self-Propelled Gas Mower Kit includes additional equipment. It comes with a 16-inch trimmer and an edger attachment. This bundle is ideal for users who want a complete yard care system without purchasing separate tools for trimming edges and clearing brush.
Are these mowers suitable for side discharge?
Yes, several models support side discharge. The PowerSmart 22-Inch Gas Self-Propelled Lawn Mower explicitly lists side discharge as a function alongside mulching and bagging. This allows you to clear debris quickly by ejecting grass clippings to the side, which is useful for maintaining open yard spaces.
How heavy are the heaviest PowerSmart 170cc mowers in this list?
The heaviest model is the PowerSmart 22-Inch Gas Self-Propelled Lawn Mower at 75 pounds. Another heavy option is the 22-Inch 170cc Self-Propelled Mower at 68 pounds. Heavier mowers can offer better stability on slopes, but you need adequate storage space and strength to maneuver them.
What engine stroke do these PowerSmart mowers use?
The PowerSmart 21-Inch 170cc Self-Propelled Gas Mower uses a 4-stroke engine. This type of engine separates oil from fuel, which typically results in cleaner emissions and less maintenance compared to 2-stroke engines. It provides consistent power for self-propelled operation and reliable performance over time.
