Starting a self propelled toro lawn mower usually involves setting the choke to the correct position, ensuring the fuel tank is full of fresh gasoline, and engaging the safety interlocks before pulling the starter cord. Many owners struggle with the first pull because they skip the choke adjustment or fail to verify that the drive system is disengaged, which prevents the engine from firing. Understanding the specific sequence for your model ensures a reliable start without straining the recoil assembly.
The process varies slightly between models with manual choke levers and those with automatic choke systems. You must identify your specific engine type, as Toro uses various engine platforms including Briggs & Stratton and Kohler. Following the manufacturer’s recommended steps protects the starter mechanism and ensures the engine runs efficiently. If the mower has a self-propelled drive, you must disengage it before starting to prevent the mower from moving unexpectedly. This guide covers the essential steps, common troubleshooting points, and safety considerations for getting your mower running smoothly.
Pros
- Powerful 170cc engine with auto choke makes starting simple, even after the mower has sat in the shed.
- Rear-wheel drive gives good traction on gentle slopes and helps reduce pushing strain.
- 22-inch steel deck feels sturdy and cuts wide, shortening mowing time.
- 3-in-1 capability with a big bag gives flexibility for mulching, bagging, or side discharge.
- Tool-free height adjustment with six positions suits a variety of grass conditions.
Cons
- At 75 pounds, it's not the lightest self-propelled mower, so lifting it into a truck bed or over curbs can take some effort.
- The 60L grass bag is generous, but it fills quickly when bagging thick, damp grass.
- Some users may find the handle height less adjustable than expected, which could be a concern for very tall or short operators.
The PowerSmart 22-Inch 170cc Self Propelled Gas Lawn Mower is a walk-behind mower designed for homeowners who want the convenience of a self-propelled drive without the premium price tag of a big-name brand. It's best suited for suburban lawns, small to medium rural properties, and anyone who has a slope or uneven ground that makes pushing a mower a workout. First-time mower buyers and budget-conscious shoppers will appreciate the straightforward controls and the package of features that usually cost more.
Under the deck, the 170cc OHV 4-stroke engine delivers steady power for thick grass. The auto choke and recoil start mean you don't have to fiddle with a primer bulb or throttle; just pull and go. With a 22-inch cutting width, you're covering more ground than a 21-inch model, which trims minutes off your Saturday morning chore. The six-position height adjustment, from 1.5 to 3.9 inches, lets you keep the lawn at the right length for the season, whether you're scalping after winter or leaving it a bit taller in the summer heat.
Build quality is a strong point for this price range. The steel cutting deck feels rugged and is coated to resist rust, so it should handle a few seasons of contact with damp grass and muddy patches. The heavy-duty blade stays sharp through regular use, and when it does dull, replacement blades are standard size and easy to find. The rear-wheel drive system gives you better traction on inclines than front-wheel drive, and the large rear wheels roll smoothly over uneven ground.
In real-world use, the 3-in-1 cutting options shine. You can leave the mulching plug in for feeding nutrients back into the soil, attach the 60L bag for a clean finish before a backyard barbecue, or open the side discharge for the times when the grass is wet and heavy. Switching between modes is simple, and the bag is easy to lift and empty, though its size means you won't be running to the compost pile every few minutes.
Storage and maintenance are straightforward. The handle folds down for leaning against a garage wall or tucking into a corner of a shed, and the 75-pound weight is manageable for most users when you're not pushing it uphill. Checking oil, cleaning the air filter, and replacing the spark plug are all reachable without lifting the mower onto a workbench. The washout port isn't included, but a quick brush and rinse keeps the underside from caking up.
As for limitations, this mower isn't built for commercial landscaping crews or vast acreage. The 22-inch deck is great for a quarter-acre lot, but on several acres you'd want a rider. Also, while the self-propelled drive helps on slopes, it won't climb serious hills hands-free, and the handle lacks the premium ergonomic adjustments you'd find on pricier models. Still, for the average American homeowner who needs a reliable, easy-starting mower with real cutting versatility, the PowerSmart 22-Inch 170cc is a strong value pick.
The 22-inch steel deck and 170cc engine give this mower enough muscle for most residential lawns. The blade spins fast enough to handle thick grass without bogging down, and the mulching option shreds clippings into small pieces that break down quickly. If you prefer bagging, the 60L bag holds a surprising amount, so you won't be stopping every few rows. The side discharge works well for tall, damp grass that would clog a bag, but you'll want to clear the area of leaves and debris first.
The height adjustment offers six positions, ranging from 1.5 to 3.9 inches. That's a useful span for both early spring cutting and keeping the lawn taller during hot, dry months. The levers are easy to pull, and you can set all wheels without tools. For uneven spots, the self-propelled drive helps keep a steady pace, reducing the chance of scalping.
PowerSmart didn't skimp on the basics here. The deck is made from heavy-gauge steel with a rust-resistant coating, which is exactly what you need for a machine that lives in a damp garage. The blade is solid and holds its edge through a full mowing season, and when it needs replacing, it's a common size. The rear wheels are large and have a deep tread, giving the self-propelled drive plenty of grip on dewy grass and packed dirt.
The overall assembly is straightforward, with most parts already attached. The handle folds down for storage, which is handy for apartments or tight sheds, though it doesn't fold flat for vertical hanging like some more expensive models. The controls are clearly labeled, and the engine has a low oil sensor to prevent damage, which is a nice safety touch for first-time owners.
Pros
- Simple DIY installation saves time and money on service fees.
- Smooth and consistent pull reduces arm fatigue when starting.
- Precisely engineered to match OEM specifications for a secure fit.

Pros
- Reliable 170cc OHV engine with auto choke for easy starts, even after the mower has sat for a few weeks.
- Steel deck adds durability and impact resistance compared to lighter polymer decks, especially if you occasionally hit a rock or root.
- Self-propelled rear-wheel drive gives confident traction on gentle slopes and uneven ground without requiring you to push hard.
- 3-in-1 mowing options (mulch, bag, side discharge) make it a versatile tool for spring grass, summer clippings, and fall leaves.
Cons
- At 59 pounds, the mower feels solid but may be heavy for some users to lift over curbs or load into a truck, despite the self-propelled drive.
- The 21-inch cutting width is standard for residential mowers but not ideal for very large rural lawns where a wider deck would save more time.
- Gas engine operation requires regular maintenance like oil changes and spark plug checks, which may be less appealing to eco-conscious or low-maintenance buyers.
The PowerSmart 21-Inch Self Propelled Gas Lawn Mower is a classic walk-behind gas mower designed for residential yard work. It pairs a 170cc OHV 4-stroke engine with rear-wheel self-propelled drive and a durable steel deck, offering a practical middle ground between a basic push mower and a premium lawn tractor. For homeowners with a quarter-acre lot, suburban lawns, or slightly sloped properties, this type of mower delivers the power and traction you need without the expense or storage footprint of a riding mower.
This mower is best suited for homeowners who want dependable cutting performance with less physical effort. The self-propelled rear-wheel drive is especially helpful on gentle slopes and uneven terrain, so you can guide the mower rather than muscle it. First-time mower buyers will appreciate the auto choke system, which simplifies starting compared to older gas mowers that require manual priming and choking. Budget-conscious shoppers get a solid set of features at a reasonable price point, while those with mobility concerns may find the self-propelled drive reduces strain during a full yard mowing session.
In real-world lawn care, the 21-inch steel deck handles standard residential grass well. The 3-in-1 capability means you can mulch clippings to feed the lawn, side discharge thick grass to avoid clumping, or attach a rear bag (sold separately, depending on package) for a clean finish before a backyard barbecue or holiday gathering. The 6-position height adjustment from 1.5 to 3.9 inches gives you enough range to keep cool-season grasses longer in summer or cut warm-season lawns shorter in spring. The 170cc engine provides enough torque to power through damp grass after a spring rain, although very wet or overgrown grass will still require slower passes to avoid stalling or clogging.
Build quality is centered around the steel deck, which offers better durability and impact resistance than many polymer decks in this price range. The foldable handle is a practical feature for storing the mower upright in a garage or shed, and the 59-pound weight is manageable for most users when rolling, though lifting it into a vehicle or over a curb takes some effort. The rear-wheel drive system gives good traction on moderate slopes, and the 21-inch cutting width is a good balance between maneuverability around landscaping and efficiency for open lawn areas. Users with very tight spaces or complex garden layouts may find a smaller 20-inch model easier to turn, but this mower remains reasonably agile for its deck size.
Maintenance is typical for a gas mower. You will need to check the oil before the first start, change it periodically, keep the air filter clean, and inspect the spark plug each season. The engine is designed for simple access to these components, and blade replacement is a standard job that most DIY homeowners can handle with basic tools. Cleaning the underside of the deck after each use helps prevent grass buildup and rust, and the steel deck should hold up well if you keep it dry between mowings. The self-propelled drive reduces the physical effort of mowing, but the gas engine does produce noise and emissions, so early Saturday morning sessions may not be the quietest option for close neighbors.
Realistic limitations include the need for regular gas engine upkeep, the 59-pound weight when lifting, and the fact that this mower is not designed for commercial landscaping crews or extremely large rural acreage. For a typical suburban home, a 21-inch self-propelled gas mower like this is a reliable workhorse that can handle weekly cutting, fall leaf mulching, and the occasional overgrown patch after vacation. If you are a homeowner looking for an affordable, dependable walk-behind mower with useful features like self-propelled drive and 3-in-1 versatility, the PowerSmart model is worth considering. Just be prepared to perform basic maintenance and store it properly to get the longest service life out of the steel deck and engine.
This mower gives you three ways to handle grass clippings. For mulching, the cut grass is finely shredded and returned to the lawn, which helps retain moisture and recycle nutrients. Many homeowners find mulching the best option during regular weekly mowing in summer when grass growth is steady and clippings are short. The 170cc OHV engine provides enough power to keep the blade spinning at high speed, which is essential for a clean mulch cut.
When grass is thick or slightly damp, side discharge is often the better choice because it moves clippings out of the deck quickly and reduces the chance of clumping. This is useful for the first mow of spring or after a week of heavy growth. For a pristine finish before a gathering, the rear bag (if included, otherwise sold separately) collects clippings neatly and makes disposal easy. The bagging system works best when the grass is dry and you mow at a moderate pace.
Switching between modes is straightforward with the included plugs and chute. You should always remove the side discharge chute when mulching to ensure proper airflow inside the deck. For fall leaf cleanup, mulching leaves into the lawn can be a real time saver, provided the leaves are not too thick. Overall, the 3-in-1 flexibility makes this mower a practical partner for year-round lawn maintenance.
The steel deck is the cornerstone of this mower's build. Steel is heavier than plastic or aluminum, but it offers excellent impact resistance and long-term durability. If you accidentally hit a rock, a tree root, or a hidden garden stake, the steel deck is more likely to bend or dent rather than crack. Over time, a steel deck also makes it easier to remove grass buildup because you can scrape it without worrying about damaging the housing.
The 59-pound weight reflects the solid construction. The wheels are designed for residential use, and the rear-wheel drive system adds traction for slopes. The foldable handle is made of sturdy tubes and locks into place during operation, which is important for safety and control. The painted finish on the deck helps resist rust, but you should still avoid leaving the mower out in the rain and keep the underside clean. With reasonable care, this mower can provide many seasons of dependable service for the home lawn.
Keeping this gas mower running well is mostly about routine checks. Before each season, inspect the oil level and top off with the recommended 4-stroke oil. Change the oil after the first 5 hours of use, then once a year or every 25 hours of operation. The air filter should be cleaned every few mowings and replaced if it looks worn. The spark plug should be removed and inspected annually, with replacement if the electrode is worn or fouled.
The blade will eventually need sharpening or replacement, especially if you hit branches or rocks. Always disconnect the spark plug wire before working under the deck. Use a socket wrench to remove the blade bolt, sharpen or replace the blade, and reattach it securely. To clean the deck, tip the mower with the spark plug side up (or use a stick to scrape off grass from above) and remove wet clippings after each use. For winter storage, drain the fuel or add a fuel stabilizer, clean the deck, and fold the handle for compact storage in a dry place.

This mower is best suited for suburban lawn owners, first-time mower buyers, and budget-conscious shoppers who need a versatile machine for weekly mowing and seasonal yard cleanup. The 3-in-1 system allows you to mulch clippings for lawn health, bag them for a tidy finish, or rear discharge them when grass is thick. The single-lever height adjustment lets you quickly change cutting height from 1.5 to 3.9 inches, so you can leave grass longer during hot summer months or cut it shorter in spring and fall. Many users appreciate the convenience of not needing tools to adjust the deck height.
Build quality is a key consideration for any gas mower, and the PowerSmart features a durable steel deck with a rust-resistant finish, heavy-duty blade, and sturdy wheels. The folding handle is a standout feature for homeowners with limited storage space, allowing the mower to stand upright in a garage or shed corner. Assembly is straightforward and requires no tools, which is a big plus for first-time buyers who may not be mechanically inclined. The engine is designed for easy maintenance, with accessible oil fill and air filter, so you can keep the mower running smoothly season after season.
In terms of practical performance, the self-propelled drive offers a comfortable pace for mowing medium to large lawns. The rear-wheel drive gives good traction on gentle slopes, and the 22-inch cutting width strikes a nice balance between agility and speed. However, users should be aware that the mower weighs 68 pounds, which is typical for a gas model but may be heavy for some to lift or maneuver in tight spaces. The grass bag capacity is adequate for average-sized lawns, but you may need to empty it more frequently when bagging thick, damp grass. Some users report that the rear discharge chute can clog in very wet conditions, so it's best to mow when grass is dry for optimal performance.
Overall, the PowerSmart 22-inch self-propelled gas mower offers a lot of value for the price. It's a reliable workhorse for homeowners who want a gas-powered option without the premium cost of high-end brands. The combination of a powerful engine, self-propelled drive, and versatile cutting options makes it a great fit for suburban lawns, first-time buyers, and anyone who wants a dependable mower for routine yard maintenance.

The standout feature is the continuously variable transmission (CVT) which offers six speed selections. You simply shift the lever and the mower smoothly adjusts its pace to match your walking speed. No more constant tweaking of a traditional drive control.
This mower is best suited for homeowners with relatively flat lawns who value convenience. The automatic choke system eliminates the need to prime or choke the engine, so starting is as simple as pull and go. The 3-in-1 capability allows you to mulch, bag, or side-discharge clippings, giving you flexibility depending on the season or your lawn care routine. The MaxFlow deck design keeps clippings suspended longer, which improves mulching quality and reduces clumping.
Build quality is decent for the price range. The steel deck feels sturdy, and the high rear wheels with aggressive tread provide solid traction on dry grass and gentle slopes. However, the front-wheel drive system is less effective on steep hills or very uneven terrain. Some long-term reviews mention the drive belt can slip or require periodic adjustment, so plan for occasional maintenance. At nearly 85 pounds, the mower is heavy to push if you lose power, but the self-propelled system handles most of the work.
Ergonomically, the handle adjusts to your height, and the single-lever height adjustment is easy to use. The deck washout port is a real time-saver just attach a hose and flush out grass buildup. The mower also folds for compact storage, a nice bonus for small garages.
Overall, the YARDMAX YG2860 is a solid choice for the budget-conscious homeowner who wants a self-propelled mower with easy starting and variable speed control.

For the price, this mower provides solid value for flat to moderate terrain.
The primary goal is to get the engine running smoothly while ensuring the self-propelled drive is safely disengaged. Most Toro self-propelled mowers use a recoil starter, and the starting sequence depends on whether the engine has a manual or automatic choke. You should always check the fuel level and quality before attempting to start, as old fuel can cause starting issues. The drive disengagement is a critical safety step that prevents the mower from moving forward as soon as the engine starts.
| Step | Action | Purpose |
|---|---|---|
| 1 | Check fuel level and quality | Ensure sufficient fresh fuel for ignition |
| 2 | Disengage self-propelled drive | Prevent mower movement during start |
| 3 | Set choke position | Adjust air-fuel mixture for cold start |
| 4 | Engage blade brake/disengage blade | Reduce load on starter mechanism |
| 5 | Pull starter cord firmly | Initiate engine ignition |
| 6 | Adjust choke to run position | Optimize air-fuel mixture for running |
Before you begin, verify that the fuel tank contains fresh gasoline mixed with the correct oil ratio if it is a 2-stroke engine, though most modern Toro mowers use 4-stroke engines that take pure gasoline. Old fuel degrades quickly and can clog the carburetor, making starting difficult. Ensure the fuel cap vent is open and not clogged with debris. The self-propelled drive lever or button must be in the off or disengaged position. This is often a lever on the handle or a button that must be depressed.
Engaging the blade brake or disengaging the blade reduces the load on the engine during the initial start, making it easier to pull the cord. On many models, the blade is automatically disengaged when the drive is off, but always check the specific manual for your model. Pull the starter cord firmly and quickly in a smooth motion. Do not let the cord snap back; hold it as it retracts. If the engine does not start on the first pull, wait a few seconds and try again. Adjust the choke to the run position once the engine starts and warms up slightly.
- Verify fuel tank is at least one-quarter full with fresh gasoline
- Ensure self-propelled drive lever is in the disengaged position
- Check that the blade brake is engaged or blade is disengaged
- Set choke to rich or start position for cold engines
- Pull starter cord firmly and smoothly without letting it snap
- Move choke to run position after engine starts
- Allow engine to idle for a minute before engaging blade
- Engage blade and drive only when ready to mow
Fuel and Choke Settings for Cold Starts
Fuel quality is the most common cause of starting problems in gas-powered mowers. Gasoline begins to degrade within 30 days of mixing, forming gums and varnishes that clog the carburetor jets. If your mower has been sitting for more than a month, drain the old fuel and refill with fresh gasoline. For 4-stroke engines, use regular unleaded gasoline with an octane rating of 87 or higher. Do not use fuel stabilizer unless you plan to store the mower for an extended period, as it can sometimes affect starting performance in cold conditions. The choke position is critical for starting a cold engine.
The choke restricts airflow to the carburetor, enriching the fuel mixture to help ignition. Most Toro mowers have a manual choke lever with positions for start and run. Some models have an automatic choke that adjusts itself, but you should still verify the setting if starting is difficult. For a cold start, set the choke to the rich or start position. Once the engine fires and runs for a few seconds, gradually move the choke to the run or lean position. If the engine stalls when you move the choke, it may indicate a carburetor issue or a clogged air filter.
Drive Disengagement and Safety Interlocks
Self-propelled mowers have a drive system that moves the mower forward as you walk behind it. This system must be disengaged before starting the engine to prevent the mower from moving unexpectedly. On most Toro models, the drive is controlled by a lever on the handle or a button that must be depressed. The lever is usually in the up or off position when disengaged. Some models have a safety interlock that prevents the engine from starting if the drive is engaged. This is a safety feature designed to prevent accidents. Always verify that the drive is disengaged before pulling the starter cord.
If the mower moves forward as soon as the engine starts, immediately shut off the engine and check the drive lever. A stuck drive lever can indicate a mechanical issue that needs repair. Do not attempt to start the mower with the drive engaged, even if you think it is safe. The self-propelled drive can provide significant forward force, which can cause loss of control or injury. Follow the manufacturer’s safety guidelines for engaging and disengaging the drive system. If you are unsure how the drive works on your specific model, consult the owner’s manual before starting the engine.
Recoil Starter Mechanism and Pull Technique
The recoil starter is the mechanism that spins the engine crankshaft to initiate ignition. It consists of a flywheel, a rope, and a handle. The flywheel has a one-way clutch that allows the rope to spin the engine but prevents it from spinning back when you release the handle. Pulling the starter cord requires a firm, smooth motion. Do not pull slowly or weakly, as this will not generate enough momentum to start the engine. Do not yank the cord or let it snap back, as this can damage the starter mechanism or cause injury. Hold the handle firmly and pull the cord in a straight line.
If the engine does not start on the first pull, wait a few seconds and try again. Do not pull the cord more than 10 times in a row without letting the engine cool down. If the engine backfires or sputters, check the fuel mixture and choke setting. A damaged recoil starter can be difficult to repair, so use proper technique to extend its life. If the starter rope frays or breaks, replace the assembly immediately. Do not use a damaged starter, as it can cause the rope to snap and whip back, causing injury. Consult the owner’s manual for specific starter maintenance instructions for your model.
Troubleshooting Common Starting Issues
If the mower does not start after following the correct procedure, several issues may be at play. Old fuel is the most common culprit, as it degrades and clogs the carburetor. Drain the old fuel and refill with fresh gasoline before trying again. A dirty air filter can restrict airflow and prevent the engine from starting. Remove the air filter and clean or replace it if it is dirty or clogged. A faulty spark plug can also prevent ignition. Remove the spark plug and check the gap and condition. If the plug is fouled or damaged, replace it with a new one. A clogged carburetor can also prevent starting, especially if the mower has been sitting for a long time. Cleaning the carburetor requires disassembly and may require specialized tools.
If you are not comfortable performing this task, consult a professional. Check the battery if your model has an electric start option, though most self-propelled Toro mowers use recoil starters. If the engine starts but stalls immediately, the issue may be a clogged fuel line or a faulty fuel filter. Check the fuel line for kinks or clogs and replace the fuel filter if necessary. If the engine runs rough or stalls at idle, adjust the carburetor screws if your model allows it. Do not adjust the carburetor beyond the manufacturer’s recommended settings, as this can damage the engine. Consult the owner’s manual for specific troubleshooting steps for your model.
Maintenance Tips for Reliable Starting
Regular maintenance is essential for reliable starting and overall mower performance. Change the oil as recommended by the manufacturer, usually every 50 hours of use or once a season. Use the recommended oil type and viscosity for your engine. Clean the air filter regularly, especially if you mow in dusty conditions. A clean air filter ensures proper airflow and fuel mixture. Check the spark plug annually and replace it if it is worn or fouled. A clean spark plug ensures reliable ignition. Inspect the fuel system for leaks or clogs, and replace the fuel filter annually. Use fresh fuel and add fuel stabilizer if storing the mower for more than 30 days.
Clean the underside of the deck after each use to prevent grass buildup, which can affect performance and cause rust. Check the blade for damage and sharpen it if it is dull. A sharp blade cuts grass cleanly and reduces engine load. Lubricate the moving parts of the drive system as recommended by the manufacturer. Store the mower in a dry, well-ventilated area to prevent rust and moisture damage. Following these maintenance tips will help ensure your mower starts reliably and performs well throughout the season. If you encounter persistent starting issues, consult a professional for diagnosis and repair.
