PowerSmart 21-Inch Self-Propelled Gas Lawn Mower
If you have slopes, thick grass, or simply want to save your energy, the PowerSmart 21-Inch Self-Propelled model is designed to do the heavy lifting for you. I immediately noticed the extra grunt of the upgraded 170cc OHV engine, which powers through dense patches of weeds without bogging down. The defining feature is the rear-wheel drive system paired with 10-inch rear wheels that dig in and pull the machine up inclines with minimal effort on your part. You get a robust 21-inch cutting width that makes quick work of larger lawns, cutting down on total cutting time. The 6-position height adjustment is controlled by a single, solid lever, allowing you to change your cutting height from 1.5 to 3.9 inches instantly.
Key Features

Choosing a Push Lawn Mower vs Gas Self-Propelled: Key Differences That Matter
Understanding the practical differences between a standard push lawn mower vs gas self-propelled models will help you avoid buyer’s remorse.
Performance Comparison
The engine sizes tell a clear story here. The push model uses a 144cc engine, which is highly efficient and lightweight. Because it only has to spin the blade, all of its power goes directly into cutting. The self-propelled model upgrades to a larger 170cc engine. This extra displacement is necessary because the engine must split its energy between spinning the cutting blade and driving the rear wheels. If you let your grass grow too tall, the 170cc engine will handle the abuse much better, whereas the 144cc engine might require you to slow down your walking pace to prevent stalling.
Price and Value Analysis
Generally, push mowers are more affordable upfront. They contain fewer moving parts, which translates to a lower retail price and lower long-term maintenance costs. You will not have to worry about drive belts wearing out, pulley adjustments, or transmission wear. The self-propelled model carries a price premium. However, the value lies in the physical energy you save. If a self-propelled drive prevents back strain or allows you to cut your lawn during hot summer days without exhaustion, the extra investment pays for itself quickly.
Build Quality Comparison
Both machines utilize a durable 21-inch steel deck, which is a massive upgrade over the plastic decks found on many modern mowers. However, the self-propelled version feels heavier and more substantial. The drive axles, transmission gears, and single-lever height adjustment mechanism add complexity and weight. The push model relies on a simpler, lightweight chassis with double ball-bearing wheels. While both are built to last, the push model has fewer points of failure over a ten-year lifespan.
User Experience Differences
Operating these two mowers offers completely different physical sensations. With the push model, you are in total control of the pace. It is highly agile, making it easy to pivot, pull backward, and weave around delicate flower beds. The downside is that you will feel the burn in your calves after half an hour, especially when pushing uphill. The self-propelled model requires you to guide the machine rather than push it. It digs into the soil and climbs hills easily, but it can feel a bit more cumbersome when you need to pull backward or make sharp 180-degree turns in tight spaces.
Which Should You Choose?
If you have a flat, uniform yard that is under a quarter of an acre, the lightweight push model is likely your best option. It is easy to store, highly maneuverable, and saves you money on both the initial purchase and future maintenance. You will appreciate how easy it is to lift into a shed or car trunk.
If your property features rolling hills, ditches, or steep slopes, the self-propelled model is the clear winner. The rear-wheel drive system prevents slipping on damp grass and eliminates physical fatigue. It is also the superior choice for larger properties or for homeowners who struggle with joint pain or limited physical strength.
My final verdict favors matching the tool to your terrain. For flat, simple lawns, choose the simplicity of the push walk-behind. For challenging slopes and thick grass, invest in the power of the self-propelled drive.
Frequently Asked Questions
Q: In the battle of push lawn mower vs gas self-propelled, which is better for steep hills?
A: The gas self-propelled mower is significantly better for steep hills. Its rear-wheel drive system provides the necessary traction to pull the machine upward, preventing you from slipping or experiencing extreme physical fatigue.
Q: Does a push lawn mower vs gas self-propelled require different types of engine maintenance?
A: The engine maintenance is very similar, as both require regular oil changes, air filter cleanings, and fresh spark plugs. However, the self-propelled model requires additional maintenance over time to check the drive belt tension and ensure the transmission gears remain clean.
Q: Can you use a self-propelled gas mower as a regular push mower if the drive system is turned off?
A: Yes, you can push a self-propelled mower manually by simply not engaging the drive lever. However, because of the heavy internal transmission and drive components, it will feel much heavier and harder to push than a dedicated manual push model.
Q: Which mower style is better for tight spaces and complex landscaping?
A: The standard push mower is superior for tight spaces. It is lighter, has a shorter footprint, and can be pulled backward or spun around on its rear wheels with minimal effort, making it highly agile around gardens.
Q: Do these mowers require mixed gas and oil?
A: No, both models feature 4-stroke engines. This means they take regular unleaded automotive gasoline in the fuel tank and standard engine oil in a separate crankcase. You do not need to mix gas and oil.
Q: How do I store these mowers during the winter months?
A: For both models, you should either run the engine until the fuel tank is completely empty or add a high-quality fuel stabilizer to a full tank of fresh gas. Store them in a dry, covered space like a garage or tool shed to prevent rust on the steel decks.
