Quick Specs and What’s in the Box (Battery, Charger, Mower, Blower)
Check what you get right out of the box: the Greenworks 80V kit includes the 21″ brushless push mower, a 500 CFM axial leaf blower, two 2.0Ah lithium‑ion batteries, and a 30‑minute (4A) rapid charger. You’ll appreciate the steel 21″ deck, brushless motor, and three mowing modes—mulch, bag, side discharge—plus vertical storage to save space. The combo feels complete, though you might consider spare batteries for longer sessions; rapid charging helps but won’t replace extra cells. They include basic safety accessories in documentation; you’ll want gloves, eye protection, and routine checks to keep the kit reliable and shared. This kit is well suited for the needs of typical homeowners who maintain their property on a regular basis and value reliable, battery-powered lawn care battery lawn mowers.
Real-World Cutting Performance : Runtime, Cutting Quality, and Height Range
While runtimes will vary with grass thickness and battery age, the twin 2.0Ah batteries deliver solid short-session performance—you can expect roughly 25–35 minutes of mowing on a typical suburban lawn before the 4A rapid charger or a spare pack is needed. In practice, you’ll notice modest battery sag during heavy, wet grass or long hills, so plan breaks. Cutting quality is clean thanks to the brushless motor and 21” deck; striping won’t rival gas, but clippings disperse evenly. The 7-position height range (1″–7″) handles fine turf to taller growth, though blade clogging can occur in damp conditions. This model fits well into a lineup aimed at careful homeowners who maintain their property regularly.
Usability and Convenience : Weight, Push Operation, LED, Storage, and Assembly
Because the Greenworks 80V mower tips the scales at about 69 pounds, you’ll feel the heft when positioning and pushing it, but the hand-push design and well-balanced steel deck keep it manageable across a typical yard. You’ll appreciate lightweight portability compared with gas rigs, though steeper slopes demand care. Seven-position height adjustments are quick and intuitive, and tool free adjustments simplify setup. LED lights let you finish early morning or twilight jobs confidently. Vertical storage saves garage space, and assembly is straightforward with clear instructions — you’ll join other owners who find this mower both practical and welcoming to use. This model is part of a lineup aimed at the typical homeowner who maintains their property regularly and prefers electric lawn mowers.
Accessories, Charging & Maintenance : Batteries, Rapid Charger, Mulch/Bag/Side Discharge
After getting comfortable with the mower’s handling and storage, you’ll want to understand how its battery system and 3-in-1 cutting options affect day-to-day use. You get two 2.0Ah batteries and a 30-minute (4A) rapid charger, which shortens downtime and lets your crew share batteries confidently. Practice basic battery care—store charged, avoid extremes, and use the rapid charger as recommended—to preserve runtime. The steel deck supports mulch, rear bag, or side discharge without tool swaps, and accessory compatibility feels thoughtful across Greenworks parts. Overall, the setup keeps maintenance simple and helps you feel supported in ownership. For long-term engine health on other equipment, remember to choose the correct two-cycle oil and follow manufacturer mixing ratios.
Who Should Buy This Mower (Yard Size, Terrain, and Alternatives to Consider)
If you have a small-to-medium suburban lawn—roughly up to a quarter-acre—and want quiet, low-maintenance mowing with enough power for thicker grass, this Greenworks 80V 21” push mower is a strong fit. You’ll appreciate its 21″ deck and brushless motor for small yards and communal pride in a tidy lawn. It handles modest slopes but isn’t ideal for steep sloped terrain or persistent heavy brush. If you need more torque or zero-turn speed, consider a ride-on or commercial cordless model. For tight budgets, look at lower-voltage models as budget alternatives that trade runtime for cost. As a homeowner-focused option, it pairs well with other lawn care equipment suited to regular property maintenance.
Some Questions Answered
Does the Mower Support Cruise Control or Variable Speed for the Wheels?
No — the mower doesn’t offer cruise control or variable speed for the wheels. You’ll push it manually and adjust blade height with seven positions, but the drive isn’t self-propelled or speed-adjustable. If you want variable speed or cruise control to reduce fatigue, consider a self-propelled model with throttle-like controls. You’ll still get a solid, community-friendly mower that’s easy to maintain and store, just not motorized wheel control.
Are Replacement Batteries From Other Greenworks Voltage Lines Compatible?
No — you can’t swap batteries across Greenworks voltage lines. Battery interchangeability depends on voltage compatibility, and using lower- or higher-voltage packs risks poor performance or damage. Stick with 80V batteries for that mower to guarantee safe operation and full runtime. If you want flexibility, look for official adapters or multi-voltage platforms from Greenworks, and check warranty terms so you and others in your group feel supported and confident.
Is There a Safety Lock-Off or Key for Accidental Starts?
Yes — you’ll find a safety interlock that prevents accidental starts: you have to press and hold the bail lever while engaging the blade control, so the mower won’t start on its own. This start prevention design is reassuring and easy to use, and it aligns with common cordless mower safety standards. You’ll feel included in a community that values safe, confident operation without complicated steps or extra keys.
Can the Blower Attach to the Mower for Integrated Storage?
No — the blower doesn’t attach to the mower for integrated storage. You can store both vertically to save space, but there’s no built-in mower attachment or clip for the blower. If you want a tidy setup, you’ll need aftermarket hooks, racks, or shelves. You’ll feel included choosing a simple storage solution that keeps batteries and tools together, and you’ll appreciate the convenience of vertical storage plus quick access to both mower and blower.
Are Replacement Steel Deck Parts and Blades Sold Separately?
Yes — you can buy replacement decks and blade options separately; you’ll find OEM steel deck parts and replacement blades through Greenworks or authorized dealers. You’ll want to match part numbers (model MOBL80L220) to guarantee fit and performance. Evaluate OEM versus aftermarket blades for balance and warranty implications. If you need help sourcing parts or confirming compatibility, contact customer service or join owner communities — you’ll get practical, friendly advice.
