Buying a new push lawn mower can be an exciting yet daunting task. With so many models and features to choose from, it’s hard to know where to start. If you’ve narrowed your search down to Bolens push mowers, you’ve already made a great choice. Bolens has been making quality outdoor power equipment for over 150 years.
Bolens push mowers are known for their durability, ease of use, and consistent cutting results. In this comprehensive guide, we’ll walk you through everything you need to know to find the perfect Bolens push mower for your lawn care needs and budget.
How Do I Start a Bolens Push Mower?
Starting a Bolens push mower is very straightforward. Most models have simplified starting procedures that eliminate the frustration and hassle of pull cords. Here are the basic steps:
- Check the oil level and add oil if needed. Bolens mowers need SAE 30 oil.
- Make sure you have fresh, clean gas in the tank. Don’t use old gas that has been sitting.
- Move the mower to an open, flat area of the yard. Disengage the blade if needed.
- Prime the engine by pressing the primer bulb 2-3 times. This helps get fuel into the carburetor.
- Set the throttle or speed control to the “Fast” position. This provides extra power for starting.
- Turn the ignition key to the “Start” position, or pull the recoil cord swiftly if there is no electric starter.
- Let the engine warm up for a few minutes before engaging the blade.
The mower should start in 1-2 pulls if properly primed and maintained. Always refer to the owner’s manual for model-specific starting instructions. Proper maintenance and off-season storage will keep your mower starting easily for years.
Where Can I Buy a Bolens Push Mower?
Bolens push mowers are sold at home improvement stores like Lowe’s and Home Depot. You can also find them at tractor supply stores like Tractor Supply Co. and Orscheln Farm & Home. Online retailers like Amazon and Walmart.com also carry a selection of Bolens push mowers.
When buying in-store, you can talk to a salesperson, see the mower in person, and even get help loading it into your vehicle. Purchasing online gives you more model options and the chance to read reviews before buying.
Make sure any online retailer is an authorized Bolens dealer so you receive a valid manufacturer’s warranty. Compare prices between stores and online to find the best deal. Look for sales around spring and fall when stores are trying to clear out last year’s mower models.
Key Features of Bolens Push Mowers
Bolens push mowers have many great features that make mowing your lawn easier. Here are some of the key features found on Bolens gas push mowers:

- Ergonomic handles: The handles on Bolens mowers are designed for comfort and easy maneuverability around landscaping features.
- Durable steel deck: A steel mowing deck keeps the blades stable while resisting dents and corrosion.
When comparing models, look for the size, engine, and features that best suit your yard and preferences. Keep budget in mind, but don’t sacrifice too much power or ease of use to save money.
How Much Do Bolens Push Mowers Cost?
Bolens push mowers range in price from about $175 up to $500. The price depends on the engine, features, and overall quality. Here’s what you can expect in each price range:
- $175-$250: Basic push mowers with 140-150cc engines and 20” steel decks. Few features but get the job done on small, flat yards.
- $250-$350: Mid-range models with more power, electric start, and mulching/bagging functions. Ideal balance of price and capability.
- $350-$500: Professional-grade mowers with 190cc engines, 22” decks, and premium features. Built to handle larger, complex yards for years.
Additional factors like limited-time sales and shipping costs can affect the final price. Set a budget, then get the most features and reliability you can afford. Keep in mind pricier mowers save time and last longer through heavy use.
Maintaining Your Bolens Push Mower
To maximize the life of your Bolens push mower, perform regular maintenance as recommended in the owner’s manual. Here are some key maintenance tips:
- Change the engine oil annually: Drain old oil and replace with new SAE 30 oil to protect internal components.
- Inspect/replace air filter: A dirty air filter can restrict airflow and cause issues. Check it seasonally.
- Sharpen blades: Sharp blades cut grass cleanly. Dull blades tear grass and stress the mower. Sharpen every 1-2 months.
- Check tire pressure: Properly inflated tires prevent uneven cutting. Inflate tires to the PSI listed on the sidewalls.
- Clean underside of deck: Clear grass buildup under the deck to prevent rust and allow proper air circulation.
- Inspect drive belt: The belt connects the engine to the blade. Replace if cracked or loose.
Doing this simple maintenance will keep your Bolens mower running smoothly for years to come. Always refer to your model-specific manual for maintenance procedures and schedules.
Warranty Coverage on Bolens Push Mowers
One major benefit of buying a Bolens mower is the included warranty coverage. Standard warranties include:
- Engine: 2-3 year limited warranty covering manufacturer defects.
- Mower deck: 3-7 year limited warranty on the steel deck against defects and workmanship issues.
- Other parts: 1-2 years limited warranty on parts like belts, controls, and bearings.
Bolens residential mowers used for personal yard care generally have longer warranties than commercial models. Make sure to register your mower at bolens.com to activate the warranty coverage after your purchase. Keep your receipt and maintenance records as proof of regular upkeep.
If you experience an issue caused by a defect, the component will be repaired or replaced for free within the warranty period. This provides excellent protection on your mower investment.
Troubleshooting a Bolens Push Mower That Won’t Start
A Bolens push mower that won’t start can be frustrating. Try these troubleshooting tips before taking it in for service:
- Check fuel level – Add fresh gas if tank is empty. Old gas also causes hard starting.
- Inspect/replace spark plug – The spark plug fires the engine. Replace if worn or cracked.
- Check oil level – Low oil prevents proper lubrication and engine rotation.
- Clean air filter – Clogged filters block airflow needed to run.
- Check blade brake – The blade brake stops the blade and can prevent starting if engaged.
- Test ignition system – Problems with the spark plug wire, ignition switch, or interlock system can prevent firing.
- Clear throttle linkage – Any obstructions or debris blocking the throttle linkage can cause issues.
- Clean carburetor jets – Clogged carb jets affect the fuel-air mixture. Remove and spray with carb cleaner.
Refer to your mower manual for detailed troubleshooting tips. If it still won’t start after checking these items, have a small engine repair technician service the mower.
Selecting the Right Oil for Your Bolens Push Mower
Using the proper oil in your Bolens push mower engine is essential for performance and longevity. Bolens recommends using high-quality detergent oil with an SAE viscosity rating of 30.
SAE 30 oil provides the following benefits for push mower engines:
- Optimized viscosity for easy cold starting and flow at hot operating temperatures.
- Detergent additives keep internal engine parts clean.
- Protects against wear, rust, and corrosion in the cylinder, crankcase, and valve train.
- Reduces friction and prevents sludge buildup.
Always check your mower’s manual for the oil capacity and any additional oil recommendations. Conventional and synthetic SAE 30 oils are both fine for Bolens mowers. Reputable brands like Briggs & Stratton, Castrol, and Shell make recommended oils specially formulated for push mower engines.
Change the oil after the first 5-8 hours of operation on a new mower. Then change it annually at the beginning or end of mowing season for the best maintenance. Be sure to use the oil level dipstick to check oil levels regularly and top off when needed. Proper oiling keeps your Bolens mower’s engine running smoothly all season long.
Assembling a New Bolens Push Mower
Putting together a new Bolens push mower out of the box may seem intimidating, but most mowers go together with basic tools in less than 30 minutes. Here are the key steps:
- Lay out all parts and hardware – bolts, washers, handle brackets, handle knobs, oil stick, grass bag, etc.
- Attach the upper and lower handles to the mower deck using provided hardware. Hand tighten knobs/bolts until later.
- Add oil to proper level and install dipstick. Refer to manual for capacity.
- Attach starter rope or electric key start (if equipped).
- Mount the grass catcher following instructions.
- Tighten all bolts and knobs securely once everything is assembled.
- Carefully flip the mower over onto its wheels, checking for proper assembly.
- Follow fueling instructions and then start engine to test.
Having a second person helps with handling and provides an extra set of hands when assembling. Go slow, follow all safety warnings, and refer back to the instructions anytime something is unclear. Take your time and the end result will be a properly assembled mower ready to use.
How Bolens Push Mowers Compare to Other Brands
Bolens sit among the top push mower brands in terms of power, reliability, and value. Here’s how they compare:
- vs. Troy-Bilt: Bolens have comparable features and quality at slightly lower prices. Both good mid-range options.
- vs. Toro: Bolens offer similar performance and engines for less money. Toro has more premium touches.
- vs. Yard Machines: Bolens edge out Yard Machines across build quality, cutting, and ease of use.
- vs. Craftsman: Bolens rate better for power, deck construction, and durability. Craftsman has more models to choose from.
- vs. Honda: Honda wins on engine performance and longevity. Bolens provide good results for much lower cost.
While not the premium brand, Bolens competes closely with higher-priced mowers. The combination of proven performance, durability, and value make Bolens hard to beat for budget-friendly basic mowing.
Finding Replacement Parts for Bolens Mowers
Eventually all lawn mowers need replacement parts and service. Fortunately, finding parts for Bolens push mowers is straightforward. Here are some options:
- Check Bolens.com – They have an online Parts Lookup tool and ship most parts directly to you.
- Visit your local Tractor Supply Co. or hardware store – Many carry parts for Bolens mowers or can special order them.
- Search Amazon or eBay – Large inventories and affordable pricing make finding generic parts easy.
- Check local mower shops – They often have used parts pulled from old trade-in mowers.
When possible, opt for genuine Bolens OEM parts to maintain performance and safety. But quality aftermarket parts can also work well for common items like belts, wheels, and spark plugs. Just check specs carefully prior to purchasing.
With the right replacement parts, you can extend the useful life of your Bolens mower for years past the initial purchase date.
Cleaning the Carburetor on a Bolens Push Mower
The carburetor regulates the fuel-air mixture that powers your Bolens mower’s engine. Over time, residue and varnish buildup inside the carburetor restrict this flow and prevent starting.
To clean a Bolens mower carburetor:
- Remove the carburetor per your manual’s instructions. This usually involves disconnecting fuel lines and removing the bowl.
- Take apart the carburetor carefully, laying parts in order. Gasket surfaces must remain clean.
- Soak all parts overnight in carburetor cleaner or mineral spirits. Do not soak rubber gaskets.
- Use compressed air and small wire brushes to remove lingering debris inside ports and channels.
- Rinse components in fresh cleaner. Blow dry.
- Reassemble carburetor using a service manual for proper component order.
- Reinstall on mower and test. Mower should start easily without stalling.
Patience is key – don’t cut corners or carb parts may not seat and seal properly. Cleaning the carburetor regularly helps your Bolens mower run smoothly all mowing season.
Cutting Height Tips for Bolens Push Mowers
One advantage of Bolens push mowers is the ability to adjust cutting height based on your preferences and grass type. Here are some tips:
- Start on the highest setting – Around 3.5-4 inches. Allows gradual lawn acclimation.
- Lower gradually – Drop .5 inches weekly until desired height is reached.
- 2-3 inches is ideal for most lawns – Blend of healthy grass and good looks.
- Thick grass types like fescue can go down to 2 inches – Dropping lower risks scalping.
- On thin grasses like bermuda, stay above 1.5 inches – Prevents stressing the lawn.
- Cutting lower is NOT better – Removing over 1/3 blade length harms grass health.
- Increase height in summer heat – Higher setting reduces watering needs.
- Clear debris before cutting – Prevent objects from blocking full blade rotation.
Test sections find the perfect height for each lawn area. Adjustments between seasons help grass thrive all year.
Potential Issues to Watch for on Bolens Mowers
While generally reliable, Bolens push mowers can experience some common issues to keep an eye out for:
- Hard starting – This can indicate carburetor cleaning is needed, especially if starting improves with starter fluid sprayed into the carb.
- Declining cut quality – Dull blades are often the cause. Sharpen blades or replace if bent or damaged.
- Leaking oil – Tighten the oil drain plug if loose. Replace the crankcase gasket if the leak is from that area.
- Excess vibrations – Have the blade dynamically balanced or replace it if bent. Low engine speed also causes vibrating.
- Tire wear/damage – Replace worn tires for optimal maneuverability. Check tire pressure and front wheel alignment.
- Rust on deck – Paint scratches expose the steel deck to moisture/rust. Touch up paint helps prevent this.
- Pulling left/right – May indicate misaligned rear wheels. Loosen and straighten wheels.
Minor issues can become major problems if left unattended. Fix problems early to keep your mower performing its best.
Sharpening the Blades on Bolens Push Mowers
Sharp mower blades are crucial for a clean, even cut. Bolens recommends sharpening mower blades after every 25 hours of use. Here are some tips:
- Disconnect the spark plug before servicing to prevent accidental starting.
- Block the blade from spinning using a wooden block between the housing and blade.
- Remove the blade bolts using a socket wrench and wood block to prevent spinning.
- Clean the top/bottom of the blade to inspect for excess wear and damage.
- Use a hand file, bench grinder or Dremel tool to sharpen blades at a 25-30° angle.
- Sharpen both edges evenly to maintain balance. Avoid overheating metal while sharpening.
- Reinstall the blade with new bolts/washers. Tighten to manufacturer torque specs.
- Test rotation and clearance before mowing. Blades should not rub or strike the mower deck.
Store extra replacement blades so dull ones can quickly be swapped out. Proper sharpening maximizes cutting performance.
Fuel Recommendations for Bolens Push Mowers
Bolens push mowers require fresh, clean unleaded gasoline for optimal performance and engine life. The owner’s manual provides specific fuel recommendations:
- Gasoline octane rating: 87 or higher to prevent pre-ignition issues.
- Ethanol content: 10% or less to avoid corrosion problems from higher ethanol levels.
- Gasoline age: Use fuel less than 30 days old. Old gas creates varnish and clogs carburetors.
- Fuel stabilizer: Add stabilizer to prevent gas breakdown during storage periods over 2-4 weeks.
- Mix oil: Do not mix oil directly with gasoline in Bolens 4-stroke engines.
- Safety: Handle fuel carefully. No smoking, sparks, flames, or other ignition sources when refueling.
Adhering to these fuel guidelines enhances performance. Always use fresh, clean unleaded gas with the recommended octane rating. Avoid gasoline blended with more than 10% ethanol if possible. Properly stored fuel keeps your Bolens mower running smoothly.
How Long Should a Bolens Push Mower Last?
When properly maintained, a Bolens lawn mower should provide reliable service for 5-8 years. The engine is generally designed to operate for this duration when given proper care and maintenance.
However, several factors affect longevity:
- Maintenance: Regular oil changes, filter cleaning, blade sharpening, etc. preserve components.
- Usage: Commercial mowing wears mowers faster. Opt for commercial models for multi-hour daily use.
- Storage: Protecting the mower from weather and off-season fuel stabilization maximize life.
- Operating conditions: Rocky or hilly terrain leads to more wear than flat yards.
Parts wear out over time regardless of maintenance. Expect to replace consumables like belts, wheels, and batteries every 2-3 years with regular use.
While individual parts may require replacement, you can keep a Bolens mower running for a decade or more with diligent care and maintenance. That represents great value for your purchase.
Winterizing Your Bolens Push Mower
Preparing your Bolens push mower for winter storage will ensure it starts easily next spring:
- Change the engine oil to remove contaminants that cause corrosion.
- Fully charge the battery (if electric start model) and remove it from the mower. Store battery indoors.
- Drain all fuel from the tank and carburetor. Stabilized fuel left over winter can gum and varnish.
- Replace fuel filter to remove debris and water that accumulated during mowing season.
- Sharpen, balance, and coat mower blades with preventative lubricant to avoid rust.
- Spray deck underside with protective silicone to repel moisture and prevent rust/corrosion.
- Clean mower deck of all grass clippings and debris using a stiff brush.
- Store mower in a covered shed or garage, away from rodents that may chew wires or rubber parts.
Taking these precautionary steps minimizes wear and protects your mower from elements that shorten its usable life. Just be sure to prep the engine properly when firing it up next spring.
