- You prefer electric tools with fade-free power and dual-port auto-switch tech.
- You need a compact 13-inch cutting path for edges and tight spaces.

- You prefer gas power with an 8-position height adjustment for thick weeds.
Verdict: Choose the Greenworks if you value electric convenience and a smaller footprint for detailed trimming. Pick the BILT HARD if you need more power and width for larger yards with less physical effort. Your choice depends on whether you prioritize maneuverability or cutting capacity.
Drive Type and Cutting Width
Drive Type
Product A is a push model, meaning you must physically push it forward while trimming. This requires more effort from you, especially on slopes or uneven terrain. Product B features a self-propelled drive system that moves at a steady 1.9 mph. This automated movement allows you to guide the unit without pushing, significantly reducing fatigue during extended use on large or rough yards. The self-propelled mechanism handles slopes and uneven ground with minimal effort, letting you focus on steering rather than exertion. For users prioritizing ease of movement, the self-propelled design offers a clear advantage over the manual push requirement.
Cutting Width
The cutting width determines how much ground you cover in a single pass. Product A has a 13-inch cutting path, which is suitable for tight spaces, edges, fences, and landscaping areas. This narrower width allows for greater maneuverability in confined spots. Product B offers a much wider 22-inch cutting diameter. This wider swath clears more ground per pass, saving time when tackling larger properties or overgrown areas. The 22-inch path is more efficient for open spaces where maneuverability around obstacles is less critical. If you need to cover large areas quickly, the wider cutting path of Product B is more effective.
Power Source
Product A runs on a 60V battery system, providing fade-free power with no memory loss after charging. It is compatible with over 75 Greenworks 60V tools, allowing you to share batteries across a full yard system. This electric setup offers quiet operation and zero emissions at the point of use. Product B uses a 170cc 4-cycle gas engine with manual recoil start. Gas engines typically offer higher continuous power for tough jobs like thick brush or dense weeds. However, they require fuel mixing or pure gas, regular maintenance, and produce exhaust. Your choice depends on whether you prefer the convenience of shared electric batteries or the raw power and independence of gas.
Deck Material
Product A features a heavy-duty steel deck with a rust-resistant design, built to handle rain, damp grass, and tough conditions. The steel construction adds durability and stability during operation. Product B also utilizes a durable, one-piece steel deck. This design minimizes vibration and adds stability on rough terrain, which is beneficial for uneven lawns. Both units prioritize robust steel construction to withstand the rigors of yard work. The steel decks on both models offer similar benefits in terms of durability and resistance to damage from debris. There is no significant difference in deck material between the two options.
Battery Capacity
Product A includes 4.0Ah and 5.0Ah batteries, with a dual-port auto-switch technology that seamlessly switches to a second battery when the first drains. This feature allows for continuous operation without stopping to swap batteries manually. The system supports up to three batteries in some configurations, extending runtime significantly. Product B is gas-powered, so it does not use batteries for operation. Its runtime is limited only by its fuel tank capacity, which is not specified in the data. For users who want extended, uninterrupted runtime without refueling, the battery system in Product A offers a distinct advantage through its auto-switch capability.
Choose the Right Trimmer for Your Yard
Users wanting low maintenance and quiet operation
This Greenworks model uses a 60V battery system, eliminating the need for gas, oil, or mixing fuel. The 13-inch cutting path is ideal for smaller, defined edges. You benefit from fade-free power and dual-line bump feed for consistent cutting. The steel deck handles damp conditions, and the 4-year warranty covers both tools and batteries, reducing long-term upkeep concerns.
Those tackling thick weeds and large areas
The BILT HARD unit features a 170cc 4-cycle gas engine that powers through dense overgrowth and light brush. Its 22-inch cutting width clears more ground per pass than electric models. The self-propelled drive moves at 1.9 mph, reducing fatigue on slopes. Eight height adjustments and a steel deck provide stability and versatility for rougher terrain and larger properties.
Gardeners needing versatile multi-tool compatibility
This kit includes a string trimmer, leaf blower, and mower, all sharing the same 60V battery platform. You can switch batteries between tools seamlessly. The dual-port auto-switch tech extends runtime by automatically using a second battery. With compatibility across 75+ Greenworks tools, you build a unified system for all yard tasks without managing multiple different power sources or chargers.

Frequently asked questions
Is a push string trimmer hard to use on hills?
Yes, pushing a trimmer uphill requires significant physical effort. You must move the tool forward manually without any assistance. This makes it tiring on slopes. For uneven ground, a self-propelled model like the BILT HARD 22-Inch is better. Its drive system moves the unit for you, reducing strain on your legs and arms during tough jobs.
What is the best cutting width for a small yard?
A narrower cutting path is easier to manage in tight spaces. The Greenworks 60V model features a 13-inch cutting width. This size is ideal for small, flat yards. It allows for precise trimming around obstacles. A wider deck, like the 22-inch option, covers more ground but may be cumbersome in confined areas.
Do I need gas for a self-propelled trimmer?
Not necessarily. While many self-propelled units are gas-powered, electric options exist. The BILT HARD model uses a 170cc gas engine for high power. However, push models like the Greenworks 60V use batteries. You can choose based on your preference for fuel maintenance versus cordless convenience and lighter weight.
Which trimmer is better for thick vegetation?
A self-propelled gas model typically handles thick vegetation better. The BILT HARD 22-Inch has a 170cc engine and a steel deck. This robust construction helps tackle overgrown yards and tough weeds. Electric push models like the Greenworks 60V are better suited for light maintenance and smaller lawns rather than heavy-duty clearing.
Can I use the same battery for a mower and trimmer?
Yes, if you buy a compatible combo kit. The Greenworks 60V 13-Inch Trimmer is part of a 3-tool bundle. It shares the 60V battery system with other tools. This means you can use the same 4.0 Ah battery for trimming, mowing, and blowing. This reduces the need to buy multiple separate batteries.
How wide is the self-propelled trimmer deck?
The BILT HARD self-propelled trimmer has a 22-inch cutting width. This wide deck allows you to clear larger areas faster. It is designed for users who want to minimize manual effort. The wider cut is less efficient for detailed edging but excellent for open, overgrown spaces.
