Finding a retailer that provides the best pricing, features and warranty coverage for the specific Bolens model you want can take some comparison shopping. Always opt for authorized sellers for safety and reliability.

How Much Does a Bolens 20 Inch Mower Cost?

The price for a new Bolens 20 inch lawn mower can range from $180 to $500 based on the power, features and any additional options selected. Some general pricing guidelines include:

• $180 – $250 – Basic push mower with 112cc-125cc engine and recoil start.

• Check the engine owner’s manual for detailed maintenance schedules and procedures.

Taking a few minutes after each use to inspect and clean your mower helps minimize required maintenance. If you notice any mechanical issues, have it serviced promptly. Proper care promotes safety and longevity.

Bolens 20 Inch Mower Warranty Coverage

One big advantage that Bolens offers is strong warranty coverage on their lawn mowers. This includes:

• Engine – Bolens engines come with a 2 to 3 year consumer warranty through the manufacturer. This covers defects in materials and workmanship.
• Parts – Most models include at least a 2 year consumer warranty on main mower components like the deck, wheels, transmission, etc. Some exclusions apply.
• Accessories – Any included accessories often carry a 1 year limited warranty. Items like grass bags are not usually covered as long.
• Battery – For electric start mowers, the battery warranty is typically 1-2 years against defects and failure.
• Service – In some cases the mower warranty may include free labor for covered repairs at authorized Bolens service centers for a designated time period after purchase.

As with any warranty, be sure to register your mower online or by mail upon purchase and keep your receipt. Normal wear items or damage from improper use are not covered. Always check the specific warranty terms for your mower model and engine prior to buying so you understand coverage.

Troubleshooting a Bolens 20 Inch Mower That Won’t Start

It can be frustrating when your mower won’t start, but there are some common issues worth checking on a Bolens mower:

• Old gas – Drain gas over a month old and replace with fresh fuel. Old gas can clog carburetors.
• Primer bulb – Ensure the rubber primer bulb on the engine is firm. Push it a few times to move gas into the carburetor.
• Choke – Make sure the choke is on if the engine is cold. Push it off once the engine warms up.
• Spark plug – Remove and inspect the spark plug. If covered in debris or worn, replace it.
• Air filter – A dirty filter prevents air flow. Remove and clean or replace if needed.
• Blade engagement – The blade safety switch beneath the seat may be faulty. Have it repaired by a technician.
• Carburetor – Issues in the carburetor can prevent fuel and air mixing properly. Take it to an authorized service center for evaluation.
• Oil level – Low oil can cause the engine to seize up. Check the dipstick and top it up.

Persistent starting troubles may require diagnosis and repair by a small engine pro. But trying these simple fixes can resolve many common start up issues.

Choosing the Right Oil Type for a Bolens Mower

Using the proper type and weight of oil in the crankcase is critical to lubricating a Bolens mower engine and enabling optimum performance. Here are some tips:

• Most Bolens air cooled engines require SAE 30W or SAE 10W-30 detergent oil. Always check your owner’s manual.
• Synthetic blends flow better in cold temperatures so are ideal for mowers used in cooler climates or various seasons.
• Don’t use straight 30 or 10W oils as they may flow too quickly from the friction points without the detergents added.
• Stay away from non-detergent oils as they leave harmful carbon deposits over time.
• 10W-30 may be preferable for hotter climates and summer use for its lighter viscosity and better flow at higher temperatures.
• Avoid thicker oils like 10W-40 or 15W-40 as they can starve the engine of critical lubrication.
• Only substitute similar multi-grade oils like 5W-30 if specifically approved in the mower’s manual.
• Never mix oil types or viscosities as this can lead to excess friction and engine damage over time.

Stick with the weight and detergent oil specified by the engine manufacturer and change it regularly. This provides the best lubrication and cooling for a long engine lifespan.

Assembling and Setting Up a New Bolens Mower

For safety and proper functionality, it’s important to correctly assemble a new Bolens lawn mower before its first use. Here is an overview of the key steps:

• Carefully lift the mower body out of the packaging and set on a level surface. Recycle materials.
• Install the discharge chute or grass collection bag using provided hardware if necessary.
• Add oil up to the full mark on the dipstick. Most engines require about 20 ounces initially.
• Insert the metal key for electric start models or attach provided manual recoil cord.
• Ensure the blade is installed tightly with the blade bolt washer and nut below the deck.
• Attach the handlebars to the mower frame using provided hardware and ensure all fittings are tight.
• Install the starter handle into the recoil, control bail lever, and throttle control appropriately onto the bars.
• Add fuel and allow the mower to prime for several minutes before starting engine.
• Make any drive control cable or wheel height adjustments as needed for a level cut.
• Read the instruction manual fully prior to operating for critical safety information.

Taking the time to properly set up your Bolens mower helps get your equipment off to the smoothest start. Ask your retailer for assistance if needed.

How Bolens 20 Inch Mowers Compare to Other Brands

Bolens mowers are competitive with other top brands when it comes to power, build quality and features. Here’s how they stack up:

• Engine quality – Bolens uses reputable Briggs & Stratton, Kohler, and Tecumseh engines comparable to Toro, Honda, and Craftsman mowers.
• Cutting performance – Excellent cutting and discharge from the stamped steel deck on par with Husqvarna and Ariens mowers.
• Ease of use – Control layout and handling ergonomics are similar to Troy-Bilt and John Deere models. Electric start offers convenience many budgets brands lack.
• Durability – The overall construction stands up well against heavy usage compared to entry models from Yard Machines and PowerSmart. Not quite as robust as commercial Gravely or Exmark mowers.
• Noise level – Bolens are average in noise output. Quieter than most mid-range options but louder than Honda’s whisper quiet models.
• Safety features – Inclusion of blade brake clutch levers and engine guards make Bolens safer than many comparable mowers.
• Cost value – While not the absolute cheapest, Bolens provides good power and build quality for the price range relative to competitors.

Overall, Bolens mowers offer comparable quality and performance to other consumer brand equivalents with some nice convenience features at an affordable budget point. They provide a good value purchase.

Finding Replacement Parts for Bolens Mowers

Over time you may need to replace worn or broken parts on a Bolens mower to keep it maintained. Here are some options for finding genuine Bolens parts:

• Check the Bolens website which provides an exploded parts diagram lookup and ability to order parts directly for your specific mower.
• Visit an authorized Bolens service dealer who can identify the parts you need and order them on your behalf.
• Search on Amazon which stocks common replacement parts for Bolens mowers from filters to belts, blades and wheels. Double check for the right part number match.
• Look up parts on RepairClinic.com, PartsWarehouse.com or LawnmowerPros.com by mower model number. Watch instructional videos for DIY repairs.
• Search eBay for both new and used Bolens parts being resold. Compare seller ratings if going used.
• Check local lawn mower shops to see if they have access to order factory Bolens parts beyond what’s sitting on their own parts shelf.

Using OEM parts ensures proper fit and performance. With the right part number, most components can be easily ordered online or obtained through an authorized dealer’s parts department.

Cleaning the Carburetor on a Bolens 20 Inch Mower

A gummed up carburetor is a common cause of poor starting or weak, sputtering engine performance on a Bolens mower. Fortunately, cleaning the carb is a fairly straightforward DIY fix:

• Run the mower dry of gas first then disconnect the fuel line and remove the carb.
• Remove the carb bowl and float pin. Be sure not to lose the float or needle valve when disassembling.
• Spray carb cleaner into the ports and jets to dissolve built up varnish and residue inside. Let it soak briefly.
• Use compressed air to blow out the cleaned passageways. Be careful not to damage the delicate internal parts and needles.
• Rinse all metal components with fresh carb cleaner solution. Allow to fully dry.
• Reassemble the carb in reverse order being careful not to crimp the float or install components backwards.
• Reattach the carb and fuel line to the engine securely. Make sure clamps are tight with no leaks.
• Add fresh gas and try starting the mower. It should run much smoother now if the carb cleaning was successful.

Taking the time to properly clean the carburetor components extends engine performance and prevents the need for a full carb replacement. Just be very careful not to misplace small parts.

Adjusting the Cutting Height on a Bolens Mower

One advantage of Bolens mowers is the ability to choose your ideal cutting height for lawn conditions. Here is how to adjust it:

• The height adjustment lever is located above the rear left wheel. It controls all four wheel positions in unison.
• For lowering the cutting height, grasp the lever and move it toward the left. Each notch lowers roughly 1/4 to 1/2 inch.
• To raise the mower blade for a taller cut, move the lever right toward higher notch positions.
• Start at the highest level for the first mow of spring to trim winter growth without scalping.
• For regular mowing, keep the setting around 2-3 inches for most lawns to maintain optimal grass health.
• Lower height like 1-1.5 inches can be used occasionally for a “manicured” look but stresses grass. Best done in fall.
• Adjusting from the left side while holding the mower handle makes it easier to feel the notches engage properly.
• Perform a test pass on part of the yard and re-adjust until you achieve the desired result.

Take the time to dial in the right cutting height for your grass type and condition. This maximizes the mower’s performance and creates a beautiful lawn.

Common Problems to Watch for on Bolens Mowers

While Bolens mowers are generally quite reliable, a few common issues can arise with age and use just as with any machine. Being aware of these can help identify problems early and reduce repair costs:

• Hard starting – This often stems from a fouled spark plug, buildup in the carburetor jets, or bad fuel. Replacing the plug, cleaning the carb and draining old gas are the most likely fixes.
• Excess vibration – A damaged or bent blade can cause severe vibration issues. Remove and replace the blade or have it professionally balanced and sharpened.
• Uneven cut – If one side is cutting lower, the blade could be installed crooked. Reseat it properly or check for debris blocking one side.
• Leaking oil – The crankcase seal drying out is a frequent culprit. Have the seal replaced promptly before oil loss damages the engine.
• Smoking/burning smell – This points to an engine issue like low oil, bad rings or valves, or overly lean carburetor. Have a small engine pro diagnose the specific problem.
• Won’t self propel – Issues with the drive belt or traction control cable can prevent self propelled motion. Adjusting cable tension or replacing the belt typically resolves this.

Being attentive to changes in performance and following good maintenance goes a long way toward minimizing problems. But repairs may be unavoidable with enough run time.

How to Sharpen the Blade on a Bolens Mower

A sharp mower blade not only cuts grass cleanly, it consumes less power and places less strain on the engine and deck. Here’s how to sharpen a Bolens mower blade:

• Disconnect the spark plug wire so the engine can’t be accidentally started during the process.
• Use a block of wood to wedge the blade from moving as you loosen the blade bolt with a wrench or socket.
• Remove the blade and clean off any built up debris near the cutting edges. Assess wear and damage.
• Secure the blade tightly in a vise or clamp. File down any nicks and dents in the cutting edges.
• Use a bench grinder or handheld rotary tool with grinding wheel at a 22-25 degree angle along each beveled edge.
• Maintain the original sharpening angle to prevent altering blade balance. Grind evenly on each end.
• Test cut performance on scrap wood. Further hone the edges with a whetstone or file as needed.
• Reinstall the sharpened blade with the airfoils curved upward toward the deck. Tighten the blade bolt to manufacturer torque specs.

Periodic sharpening removes rounded over metal and restores a clean cutting edge. Always balance safety with a razor sharp blade.

Fuel Recommendations for Bolens 20 Inch Mowers

Using the proper type of fuel is critical to performance and engine longevity on a Bolens mower:

• Most Bolens mower manuals recommend 87 octane or higher unleaded gasoline.
• Avoid ethanol blends over 10% like E15 or E85 as they can corrode engine parts not designed for higher ethanol concentrations.
• Premium unleaded around 91 octane contains fewer impurities and less ethanol so is ideal to prevent gunking of the carburetor over time.
• Non-oxygenated reformulated or pure gasoline also avoids ethanol issues but can be hard to find and cost prohibitive for most owners.
• Consider adding a fuel stabilizer like STA-BIL to preserve fuel quality when storing the mower over winter months.
• Do NOT use diesel, kerosene, straight 2-cycle gas or any other fuel types. The wrong fuel can severely damage the engine.

Stick with standard 87+ octane unleaded gas, ideally non-ethanol if possible in your area. Limit ethanol content to 10% maximum. This provides the best performance and prevents premature deterioration of seals, gaskets and internal engine components.

What is the Typical Lifespan of a Bolens Mower?

When properly maintained, a Bolens lawn mower will typically last 6-10 years for a residential user. Lifespan depends mainly on these factors:

• Usage frequency – Mowers used 20+ times per year will wear out faster than those running just a few times per month. Commercial duty cycles shorten expected lifespan as well.
• Maintenance habits – Failure to change oil, sharpen blades, clean filters, replace spark plugs, etc leads to accelerated wear and tear.
• Storage conditions – Exposure to moisture, dramatic temperature swings and dirt in off-season decreases longevity. Use fuel stabilizer before winterization.
• Deck and housing care – Denting, rust formation and caked on grass under the deck reduces structural integrity over time.
• Fuel quality – Ethanol-heavy gas corrodes the fuel system faster. Stale gasoline leads to gummed up carburetors.
• Model grade – Consumer models average 6-8 years while heavy duty commercial units may reach 10+ years.
• Operator habits – Careless handling like over speeds, scalping and impacts reduces useful life.

With proper care, even 8-10 year old Bolens mowers can still perform well. But eventually the metal fatigue, bearing wear and normal breakdown of consumable parts will force most owners to purchase a newer replacement mower.

Winterizing Tips for Bolens 20 Inch Mowers

Putting your Bolens lawn mower into storage over winter requires some key steps to protect it until spring:

• Drain the gas tank completely or add fuel stabilizer to prevent stale gas issues. Run the carb dry.
• Change the engine oil and filter so fresh oil minimizes moisture contamination over the idle months.
• Remove the spark plug and pour about an ounce of oil into the cylinder. Crank the engine to coat internals then replace the plug.
• Lubricate any pivot points with penetrating oil spray to avoid seizing up. Grease all gear teeth.
• Remove the blade for sharpening and balancing before reinstalling tightly come spring.
• Clean the mower deck thoroughly of all grass clippings, dirt and debris to prevent corrosion.
• For electric mowers, store the battery indoors above 40°F and on a maintenance charger over winter.
• Consider covering the mower with a breathable tarp to protect from dust and humidity. Avoid plastic sheeting.
• Store the mower cleaned, dry and indoors/under cover if possible. Ideal storage is in a detached garage.

Taking a little extra time for winterization safeguards your investment and ensures your Bolens mower starts right up next season.
