You are looking for powersmart 144cc 21 inch 2 in 1 push gas lawn mower alternatives because your specific needs may differ from the original model. The PowerSmart 21-Inch Push Gas Mower Kit includes a 144cc 4-cycle engine and a separate string trimmer. It offers a 21-inch steel deck with side-discharge or mulching functions. This combination suits small yards where you want both mowing and trimming tools. However, you might prefer a different drive type, engine size, or cutting width. Some buyers need self-propelled assistance for slopes or larger battery systems for quieter operation.
We selected 6 similar picks because their published specifications overlap with the original mower. Each alternative shares core traits like a 21-inch cutting width or gas power. You will find options with 140cc engines, 80V brushless motors, or self-propelled drives. These specs address different lawn sizes and terrain challenges. We compare them strictly by their data to help you choose the right fit. This guide focuses on practical differences in drive type, engine displacement, and included equipment. You can decide based on whether you need mulching, bagging, or side discharge capabilities.
How these options compare to the original
PowerSmart 21-Inch 140cc Gas Push Mower
This model drops the included trimmer and brush cutter to focus solely on mowing. It retains a 21-inch cutting width and push drive, similar to the original. However, the engine displacement is listed as 140cc in the attributes, though the title says 144cc. It offers 3-in-1 mowing functions, adding bagging to the side discharge and mulching options found on the original. The deck is steel, and the unit weighs 31.8 pounds. You should pick this if you do not need the trimming tool and want a lighter, simpler mower for medium lawns.
Greenworks 80V 21-Inch Push Lawn Mower
This is a gas-free alternative that uses an 80V brushless motor instead of a 144cc engine. It keeps the 21-inch cutting width and push drive. The key difference is the power source, which offers quieter operation and zero emissions. It includes a 5.0 Ah battery, providing higher capacity than standard models. The unit weighs 84 pounds, significantly heavier than the gas original. You should choose this if you value quiet operation and low maintenance over raw engine power and do not mind the extra weight for small to medium lawns.
Greenworks 80V 21-Inch Cordless Push Mower
This model also uses an 80V brushless motor but with a smaller 2.0 Ah battery capacity. It maintains the 21-inch cutting width and push drive type. The primary difference is the reduced battery size, which may limit runtime compared to the 5.0 Ah version. It lacks the engine displacement of the gas original, relying instead on electric power. The unit is lighter than the battery-heavy 5.0 Ah version but still heavier than the gas mower. You should pick this if you want quiet, low-maintenance mowing on flat lawns and prefer a smaller battery setup.
PowerSmart 22-Inch 170cc Self-Propelled Gas Mower Kit
This option increases the cutting width to 22 inches and upgrades to a 170cc engine for more power. It adds self-propelled drive, removing the need for you to push the mower. It includes the same 16-inch string trimmer and brush cutter kit as the original. The unit is designed for larger, uneven properties. You should choose this if you need assistance on slopes and want more engine power. It gives up the smaller deck size of the original but provides better traction and coverage for large yards.
PowerSmart 21-Inch 140cc Self-Propelled Gas Mower
This model features a self-propelled drive system, unlike the push-only original. It has a 140cc engine and 21-inch cutting width. It offers mulching and bagging functions, providing a 3-in-1 capability. The self-propelled feature helps with traction on slopes, making it better for uneven terrain. It weighs 70 pounds, which is heavier than the original. You should pick this if you prioritize ease of movement on hills over the lighter weight and manual control of the original push mower.
PowerSmart 21-Inch 140cc Gas Push Mower
This is a push mower with a 140cc 4-stroke engine and 21-inch cutting width, very similar to the original. It offers 3-in-1 mowing functions, including side discharge, mulching, and bagging. It lacks the included trimmer and brush cutter of the original kit. The unit is designed for smaller lawns where side discharge is preferred. You should choose this if you want a reliable, simple push mower without the extra trimming tools. It provides efficient cutting with manual control but does not include the complete yard care kit.

Frequently asked questions
Does any alternative offer self-propelled drive?
Yes, several models in this list feature self-propelled drive instead of manual push. The PowerSmart 22-Inch 170cc kit and the 21-Inch 140cc bagging model both include this feature. Self-propelled drive reduces physical effort, making it easier to handle slopes or larger lawns without pushing the machine manually.
Which mower is best for small yards?
The PowerSmart 21-Inch 140cc Gas Push Mower is ideal for small lawns. It features a 21-inch cutting width and a 140cc engine. This model prioritizes side discharge and manual control. Its compact dimensions make it easy to maneuver in tight spaces where larger self-propelled units might struggle.
Are there battery-powered options available?
Yes, Greenworks offers two 80V brushless push mowers. One includes a 5.0 Ah battery, while the other comes with two 2.0 Ah batteries. These electric models provide quiet operation and require less maintenance than gas engines. They are suitable for flat, medium-sized lawns where cordless convenience is preferred.
Which model includes a trimmer or edger?
Two PowerSmart kits include additional yard care tools. The Best Overall 21-Inch Push Gas Mower Kit comes with an edger and brush cutter. The Best 16-Inch 22-Inch Self-Propelled Kit also includes these attachments. These kits are designed for homeowners who want a complete mowing and trimming solution in one purchase.
What is the difference between 140cc and 170cc engines?
Engine displacement indicates power output. The 170cc engine in the 22-Inch self-propelled model offers more torque than the 140cc engines found in other options. A larger engine helps maintain blade speed in thick grass. The 140cc models are sufficient for standard residential lawns with average grass height.
Can I mulch grass clippings with these mowers?
Most models support mulching. The 21-Inch 140cc bagging model offers mulching and bagging functions. The side discharge model also includes mulching capabilities. Mulching cuts clippings into fine pieces to return nutrients to the soil. Check the mowing functions listed for each specific model to confirm this feature.
How heavy are these lawn mowers?
Weight varies significantly by power type. The Greenworks 80V mower weighs 84 pounds due to its battery. The PowerSmart 21-Inch 140cc self-propelled model weighs 70 pounds. Lighter gas push mowers are around 31.8 pounds. Heavier units offer more stability but require more effort to lift or store.
