Best Push-Button Start Lawn Mowers for Easy Starts
As an Amazon Associate we earn from qualifying purchases.
A lawn mower push button starter lets you start the engine or motor with a button press instead of a pull cord. Four mowers in this roundup name a push-button start in their listings: two cordless brushless push mowers from Greenworks and PowerSmart, and a 131cc self-propelled gas mower from Shulemin. The sections below use only the engine, battery, deck, height and accessory details the listings state, so you can compare the four options side by side.
Quick answer
- Cordless with no gas: the Greenworks 80V 21-inch and the PowerSmart 40V 20-inch are battery mowers with a listed push-button start.
- Gas with a push-button start: the Shulemin 3-in-1 self-propelled mower is a 131cc 4-stroke model with a listed push-button start and a 50-liter bag.
- Combo kits: the PowerSmart listings include a 465 CFM leaf blower that the listing says also has a push-button start.
- Height and mulching: the PowerSmart models list six height positions, and the Greenworks listing lists seven.
What a push-button start means on a mower
On a battery mower, the push-button start replaces a key or a pull handle. You press the button, and the brushless motor runs. On a gas mower, the button usually works the starter motor or an electric start circuit. The listing for the Shulemin gas mower calls its starter a “simple push-button start” and states that the engine is a 4-stroke design. The listings do not describe the internal start circuit in detail, so check the manual for the exact start sequence and any safety lock on your model.
A push-button start is convenient, but it does not change the mower’s need for careful handling. Keep your hands and feet clear of the blade or deck before you start any mower, and never start a mower while you are standing in the cutting path.
How to choose between cordless and gas
Battery mowers in this roundup are quiet and need no fuel, oil or spark plug service. The Greenworks listing says “No gas, No oil, No emissions,” and the PowerSmart listings describe brushless motors on 40V batteries. Battery mowers depend on the charge in the pack. The Greenworks 80V listing gives up to 60 minutes of run time with a fully charged 4.0Ah battery, and the listing adds that run time varies with grass condition and operator technique. Plan your mowing around that range and keep a spare battery if your lawn is large.
A gas mower gives you refueling in place of recharging. The Shulemin listing describes a 131cc 4-stroke engine, a self-propelled rear-wheel drive system, and a 50-liter grass bag. The listing says a 4-stroke engine runs quieter and is more fuel-efficient than a 2-stroke engine, and that is the listing’s own comparison. If the job includes hills or thick grass, the self-propelled drive and the engine size matter more than the start type.
Battery capacity and charging
Battery mowers in this roundup use 4.0Ah packs. The PowerSmart 20-inch combo lists two 4.0Ah batteries and one charger, while the 17-inch combo lists one 4.0Ah battery and one charger. The Greenworks 80V listing lists a 4.0Ah battery with a charger and says it includes a 60-minute rapid charger. Charging time is in the listing or the manual for each kit. Do not charge a battery in a freezing area or leave it on a charger unattended for long periods, and follow the charger manual for the correct storage charge if the mower sits for a season.
Cutting deck, height and bagging
All four mowers are described as having a multi-mode discharge system. Greenworks lists a mulch, rear bagging and side discharge option on a 21-inch deck. PowerSmart lists 3-in-1 mulching, side discharge and rear bagging on its 17-inch and 20-inch decks, with a steel deck on the 17-inch model. The Shulemin mower lists the same three discharge modes on a 131cc gas deck, with a 50-liter bag.
Height adjustment varies. The Greenworks 80V listing describes a single-lever, 7-position height adjustment. The PowerSmart listings describe six height positions from 1.5 inches to 3.9 inches. The Shulemin listing does not state a height range in the product data, so check that listing before you choose it for a low-cut lawn.

The four lawn mowers in this roundup
1. Greenworks 80V 21 inch Push Lawn Mower, 4.0Ah Battery and Charger (B019VXKUDI)
This is a cordless push mower with a brushless motor and a 21-inch cutting deck. The listing says the brushless motor gives more torque, runs quieter, and has a longer life. It states up to 60 minutes of run time with a fully charged 4.0Ah battery, and it adds that run time varies by grass condition and how the mower is used. The mower has a 3-in-1 system for mulch, rear bagging and side discharge, and a single-lever, 7-position height adjustment. The listing names an easy push-button start, and it says there is no gas, oil or emissions. The listing model number is 2501202. The package includes a battery and charger.
This model suits a homeowner who wants a quiet cordless mower with a wide deck and a push-button start.
2. PowerSmart 40V 17 inch Brushless Cordless Lawn Mower and 465 CFM Leaf Blower (B0FJRTQ7JK)
This combo kit pairs a 17-inch brushless cordless mower with a 465 CFM leaf blower. The mower has a steel deck, 3-in-1 mulching, side discharge and rear bagging, and six height positions from 1.5 inches to 3.9 inches. The listing names a push-button start on the mower and on the blower, and it says the foldable handles make the mower easier to store. The blower is listed at 465 CFM at 115 MPH, with dual-speed control, and it tackles wet leaves, grass clumps, light snow and patio debris. Both tools run on one 40V battery system. The kit includes one 4.0Ah battery, one charger and two manuals. The mower model number is MB2480C.
The kit is useful if you want a blower on the same battery as the mower. The smaller 17-inch deck suits a small lawn or a narrow yard.
3. PowerSmart 40V 20 inch Brushless Cordless Lawn Mower and 465 CFM Leaf Blower (B0HBQ2T5XT)
This is the larger PowerSmart combo. The mower has a 20-inch deck, 3-in-1 mulching, side discharge and rear bagging, and six height positions from 1.5 inches to 3.9 inches. The listing names a push-button start on the mower and the blower. It includes the same 465 CFM blower, which the listing rates at up to 465 CFM at 115 MPH with variable speed. The kit comes with two 4.0Ah batteries and one charger, so it carries more battery capacity than the 17-inch kit. The listing states a 2-year limited warranty from PowerSmart. The mower model number is MB2486C.
Choose this model for a larger lawn where the second battery matters. The 20-inch deck covers more ground per pass than the 17-inch version.
4. Shulemin 3 in 1 Self Propelled Gas Lawn Mower, 131cc Engine (B0H339KWGN)
This is the gas option in the roundup. It has a 131cc 4-stroke engine, which the listing says runs quieter and is more fuel-efficient than a 2-stroke engine. The mower is self-propelled with rear-wheel drive, and the listing says the drive helps on slopes and uneven ground. It has a 50-liter grass bag with a wide mouth, and it offers mulching and side discharge in addition to bagging. The listing describes big wheels for stability and a simple push-button start for everyday use. The listing says to cut dry grass, clean the deck after use, and avoid tilting the mower in ways the manual forbids. The model number is 6A6066A60672AA7003.
Pick this mower if you need a gas engine and a self-propelled drive, and if the large grass bag matters for your yard. The listing does not state a deck width or a height range in the product data.
Which mower fits which lawn
For a small to medium lawn with a quiet, low-maintenance requirement, the 17-inch PowerSmart combo is a reasonable choice because the kit includes a blower and a single battery. For a larger lawn that needs more run time, the 20-inch PowerSmart combo with two batteries or the Greenworks 80V 21-inch mower with its listed 60-minute run time fits better. For hills, thick grass or a lawn with no nearby outlet for charging, the Shulemin gas mower and its self-propelled drive are the better match.
Think about the bag, too. If you collect clippings, the Shulemin 50-liter bag holds a large load before you empty it. The battery mowers offer rear bagging and side discharge, so you can choose mulching for a cleaner look and bagging only when you need it.
Safety checks before you press the start button
Read the manual before first use. Check the blade or deck for loose bolts and damage. Clear stones, sticks and toys from the lawn. Keep hands and feet clear of the blade while the mower is running, and stop the blade or motor before you clear a clog. On a battery mower, remove the battery before you clean under the deck. On a gas mower, follow the manual for fuel, oil and spark plug service, and do not fuel the mower while it is running or hot.
If the push-button start does not work, check the battery charge or fuel level first, then check the start switch and any safety key or lock described in the manual. If you are unsure about wiring or a repair, ask a qualified small-engine technician or an electrician. Do not bypass a safety switch to make the mower start.
Maintenance that keeps a push-start mower ready
Keep the deck clean, because grass buildup can slow the blade and stress the motor. Sharpen or replace the blade according to the manual’s schedule. For battery mowers, store the battery indoors at a moderate temperature and avoid leaving it on a charger after it is full. For the gas mower, change the oil and check the air filter on the schedule in the manual. Store any mower in a dry place so the start system and the deck stay in good condition.
FAQ
What is the difference between a push-button start and an electric start?
The listings in this roundup use the term push-button start, which means you press a button to start the mower. The listings do not describe the start circuit in detail, so the exact start method on each model comes from its manual.
Which mower has the longest run time?
The Greenworks 80V listing states up to 60 minutes of run time with a fully charged 4.0Ah battery, and it notes that run time varies by grass condition and operator technique. The PowerSmart 20-inch combo has two 4.0Ah batteries, which adds more total capacity. The listings do not state a run time for the gas Shulemin mower.
Do the PowerSmart kits include a blower?
Yes. Both PowerSmart listings include a 465 CFM leaf blower on the same 40V battery system. The 17-inch kit has one 4.0Ah battery and one charger, and the 20-inch kit has two 4.0Ah batteries and one charger.
Can I bag clippings with these mowers?
All four listings describe a bagging or discharge option. The PowerSmart and Greenworks listings describe rear bagging and mulching in a 3-in-1 system. The Shulemin listing includes a 50-liter grass bag and a 3-in-1 mulch, bag and side discharge system.
Is a gas mower quieter than a 2-stroke model?
The Shulemin listing says its 131cc 4-stroke engine runs quieter and is more fuel-efficient than 2-stroke models. This is the listing’s comparison, and the product data does not give a decibel rating for any mower in this roundup.
How should I store a push-start mower over winter?
Clean the deck, store the mower in a dry place, and follow the manual for the battery or fuel system. For a battery mower, keep the battery at a moderate temperature and charge it to the level the charger manual recommends. For a gas mower, follow the manual’s storage steps for fuel and oil.
Bottom line
If you want a push-button start without gas, choose one of the cordless PowerSmart or Greenworks mowers, and pick the deck size and battery count that match your lawn. If you need a gas engine and a self-propelled drive, the Shulemin 131cc mower is the match. Read the listing and the manual for the start steps and the safety lock on the model you choose.
