Greenworks 60V 21″ Brushless Cordless Lawn Mower
The Greenworks 60V 21″ Brushless Cordless Lawn Mower offers a genuine alternative to traditional gas machines. In my testing, the gas-like power delivered by the 60V brushless motor consistently tackled thick patches of grass without bogging down. The heavy-duty steel deck provides a solid, durable foundation that feels sturdy on uneven ground, while the IPX4 waterproof rating means you do not have to panic if a sudden rain shower starts mid-mow. I especially appreciate the SmartCut self-sharpening blades which automatically increase motor power when you hit dense patches. The dual-port auto-switch technology is another standout feature, instantly switching to the second battery when the first drains so you can finish your half-acre yard without a forced break.
- Gas-Like Power: The 60V brushless motor delivers 50 percent more torque than standard 40V mowers and matches the blade speed of a 150cc gas engine.
- Weather-Resistant Build: Features an IPX4 waterproof rating and a durable steel deck designed to handle damp grass and rough conditions.
- SmartCut Blade Tech: Dual blades automatically adjust their speed based on grass density and offer four-in-one bagging, mulching, side-discharge, and turbo leaf modes.
- Dual-Battery Port: Holds two batteries at once and automatically switches to the second power source when the first one runs out.
- Easy Maneuvering: Equipped with large 10-inch rear wheels, 8-inch front wheels, and bright LED headlights for low-light operation.
Pros
- Runs quietly with zero gas fumes or spark plug maintenance.
- Automatically transitions between batteries for extended runtime.
- Steel deck is much more durable than cheap plastic alternatives.
- Folds up vertically to save valuable space in your garage.
Cons
- The 5.0Ah battery makes the mower feel heavy when pushing up steep hills.
- Rapid charger fan can be quite loud during the charging cycle.
Best for:
Homeowners with up to a half-acre of standard lawn who want to ditch gas maintenance without sacrificing the power needed for thick grass.
Expert Opinion: This Greenworks mower proves that battery technology has finally caught up to gas, offering a clean, quiet, and incredibly sturdy option for weekly yard maintenance.
Husqvarna 122RJ Gas Weed Eater and Brushcutter
The Husqvarna 122RJ Gas Weed Eater and Brushcutter is a highly versatile tool designed for overgrown areas where no standard mower could ever survive. I used this machine to clear a ditch full of woody weeds, and the multi-purpose design allowed me to switch from the string trimmer head to the metal grass blade in just a few minutes. Starting a gas tool can often be a headache, but the Smart Start technology and the handy air purge system make pulling the cord surprisingly easy. The safety design includes a barrier bar with a J-handle that keeps you at a safe distance from the spinning blade while allowing you to swing the tool in wide, controlled arcs. To save your back during long clearing sessions, the package comes with an adjustable harness that distributes the weight of the engine across your shoulders.
- Two-in-One Utility: Includes both a standard bump-feed string trimmer head and a heavy-duty metal grass blade for woody brush.
- Smart Start Engine: Engineered starter mechanism reduces starter cord resistance by up to 40 percent for effortless pulling.
- Carburetor Air Purge: Removes air bubbles from the fuel system and carburetor to ensure quick cold starts.
- J-Handle Safety: Features a barrier bar and J-handle configuration to prevent the user from stepping into the cutting path.
- Supportive Harness: Comes with a padded shoulder harness to reduce physical fatigue during extended backyard cleanup jobs.
Pros
- Easily cuts through thick weeds, saplings, and dense brambles that would stall a mower.
- Lightweight engine and ergonomic handle make it easy to sweep across slopes.
- Gas power means unlimited runtime as long as you have fuel on hand.
Cons
- Requires mixing gas and two-stroke oil for every tank.
- Considerably louder than battery-powered alternatives and requires ear protection.
- Metal blade can throw sparks and debris if you strike hidden rocks.
Best for:
Property owners with steep slopes, ditches, overgrown fence lines, or dense, woody brush that a standard wheeled mower cannot physically reach.
Expert Opinion: The Husqvarna 122RJ is an absolute workhorse for raw clearing power, offering the perfect balance of safety features and reliable gas torque.
Lawn Mower vs Brush Cutter: Key Differences That Matter
Performance Comparison
A lawn mower is designed to do one job perfectly, which is cutting large, flat areas of grass to a uniform height. The Greenworks mower uses a wide 21-inch deck to cover ground quickly, relying on high blade speed to mulch or bag the clippings.
A brush cutter operates on a completely different level of raw destruction. The Husqvarna 122RJ does not care about a manicured look. It uses a high-torque gas engine to spin a metal blade through thick stalks, saplings, and tangled briars. If you try to run a lawn mower over three-foot-tall weeds or woody brush, you will bend the crankshaft. If you try to cut a neat backyard with a brush cutter, you will end up with an uneven, scalped mess.
Price and Value Analysis
When looking at the financial investment of a lawn mower vs brush cutter, you must consider what comes in the box. The Greenworks mower has a higher upfront cost, but that price includes a high-capacity 5.0Ah battery and a rapid charger. You will not need to buy gas, oil, or spark plugs for the life of the machine.
The Husqvarna brush cutter is less expensive initially, but it requires a constant supply of two-stroke oil and fresh gasoline. You also need to factor in the cost of replacement trimmer line and replacement metal blades over time.
Build Quality Comparison
The Greenworks mower features a heavy steel deck that resists rocks and debris, combined with IPX4 waterproofing that protects the sensitive electronics from moisture. It is built like a traditional gas mower, meaning it can take some serious abuse in the yard.
The Husqvarna 122RJ is built around a lightweight, commercial-grade drive shaft and gear joint. It is designed to withstand the violent vibrations of hitting thick wood. The J-handle and barrier bar are thick metal, ensuring the tool will not flex or break when you are forcing it through dense undergrowth.
User Experience Differences
Using these two tools is night and day. With the Greenworks mower, you push a button, squeeze the handlebar bale, and walk behind it. It is quiet, clean, and requires very little upper-body strength.
Operating the Husqvarna brush cutter is a physical workout. Even with the padded harness distributing the weight, you are holding the tool, steering it with the J-handle, and sweeping it back and forth across your body. You will deal with engine vibration, loud exhaust noise, and flying debris, which requires safety glasses and heavy pants.
Which Should You Choose?
If you have a standard suburban yard with a flat lawn, some garden beds, and a few trees, the Greenworks cordless lawn mower is your best choice. It will keep your grass looking pristine without the noise, smell, or maintenance of a gas engine.
If your property includes steep ditches, rocky hillsides, overgrown fence lines, or thick patches of wild blackberries and woody brush, you need the Husqvarna gas brush cutter. It goes where wheeled mowers cannot travel and cuts through vegetation that would destroy a standard blade.
For many homeowners with larger properties, the real answer is not choosing one over the other, but using them as a team. Use the Greenworks mower for the main yard, and use the Husqvarna brush cutter to tame the wild edges.
Frequently Asked Questions
Q: Can I use a lawn mower vs brush cutter to clear thick brush?
A: No, you should not use a lawn mower to clear thick brush. Lawn mowers are designed for soft grass, and hitting thick, woody stalks can bend the blade, damage the motor shaft, or turn wood debris into dangerous projectiles.
Q: Which tool is safer for steep hillsides, a lawn mower vs brush cutter?
A: A brush cutter is much safer on steep hillsides. Pushing a heavy lawn mower up or across a steep slope increases your risk of slipping and pulling the mower over your feet, whereas a harnessed brush cutter allows you to stand securely while sweeping the cutting head across the slope.
Q: Do I need a special license to operate a gas brush cutter?
A: No special license is required for residential use. However, you must wear proper personal protective equipment, including safety glasses, heavy boots, long pants, and hearing protection.
Q: How long does the battery last on the Greenworks 60V mower?
A: The included 5.0Ah battery typically provides up to 45 minutes of runtime, which is plenty of time to cut a half-acre yard under normal conditions.
Q: Can the Husqvarna 122RJ be used as a regular grass trimmer?
A: Yes, it comes with a Tap ‘n Go string trimmer head for regular lawn edging, allowing you to easily swap the metal brush blade out when you need to trim around delicate garden beds.
Q: Is wet grass a problem for the Greenworks cordless mower?
A: The Greenworks mower features an IPX4 waterproof rating and a steel deck, so it can safely cut damp grass. However, cutting wet grass of any kind can cause clipping clogs under the deck, so dry conditions are always ideal.
