You might be looking for ryobi olm1833b lawnmower battery 18v alternatives because the original unit has specific limits. The RYOBI 18V 33cm Mulching Lawnmower offers a 33 cm cutting width and 4.0 Ah battery capacity. It is designed for mulching on small, flat lawns. The 19.2-pound weight makes it easy to handle in tight spaces. However, you may need more power or a larger deck for your property. Some users require self-propelled drive types or brushless motors for better efficiency. You might also prefer a different voltage ecosystem like 60V or 56V for longer runtime. The alternatives listed here were chosen because their specs overlap with the original. They share features like mulching functions or compatible battery sizes. This guide compares 6 options based on their published specifications. You can find a model that better fits your lawn size and power needs.
How each alternative compares
Greenworks 60V 17-Inch Push Lawn Mower
The Greenworks 60V 17-Inch Push Mower uses a higher 60V system with a 4.0 Ah battery. It features a brushless motor and offers mulching and bagging functions. The cutting width is narrower at 17 inches compared to the RYOBI 33 cm deck. It weighs 37.5 pounds, making it heavier than the RYOBI option. This model suits users with existing Greenworks tools who need versatile disposal options. You gain more voltage and bagging capability but lose some cutting width and ecosystem compatibility if you stick with RYOBI batteries.
RYOBI 18V 37cm Brushless Mower
This RYOBI 18V Brushless Mower keeps the 18V ONE+ voltage but upgrades the battery to 5.0 Ah. The cutting width increases to 37 cm, covering more ground per pass. It uses a brushless motor for improved efficiency and durability. The weight is listed as 0.71 ounces in the specs, which appears to be a data error, so you should verify the actual weight. This mower is best for small yards where you already own RYOBI batteries. You get a wider cut and longer runtime but still rely on manual pushing for maneuverability.
RYOBI 18V Hybrid Lawnmower 37 cm
The RYOBI 18V Hybrid 37 cm Lawnmower offers the flexibility of using both battery and corded power. It includes a 2.5 Ah battery and features a 37 cm cutting width. The weight is 32 pounds, significantly heavier than the original RYOBI model. This option is ideal for small lawns where you want to avoid running out of battery charge. You gain the ability to plug in for unlimited runtime but sacrifice the portability of a fully cordless system. The larger deck also covers more area per pass.
Greenworks 40V 14-Inch Cordless Push Mower
The Greenworks 40V 14-Inch Cordless Push Mower is designed for tight storage spaces and small yards. It uses a 40V system with a 4.0 Ah battery. The cutting width is only 14 inches, much narrower than the RYOBI 33 cm deck. It weighs 33.3 pounds and is a push model. This mower is practical for users who prioritize compact storage over raw power. You give up a wide cutting path and the RYOBI ecosystem for a lighter, more manageable unit that fits in smaller sheds.
Greenworks 60V 21-Inch Self-Propelled Mower
The Greenworks 60V 21-Inch Self-Propelled Mower is built for large yards and uneven terrain. It features a 21-inch cutting width and self-propelled drive. The voltage is 60V with a 4.0 Ah battery, and it includes a brushless motor. It weighs 65 pounds and is designed for lawns up to three-quarters of an acre. This mower is robust and suitable for slopes. You gain significant power and ease of use on difficult terrain but pay with a larger footprint and higher weight compared to the lightweight RYOBI option.
EGO Power+ 21-Inch Self-Propelled Cordless Mower
The EGO Power+ 21-Inch Self-Propelled Cordless Mower delivers 56V power with variable speed control. It has a 21-inch cutting width and a 4.0 Ah battery. The weight is 77.2 pounds, making it the heaviest option listed. It is designed for medium lawns needing reliable performance. This mower offers variable speed self-propulsion for better control on slopes. You gain advanced drive features and substantial power but accept a heavier machine and a different battery ecosystem than the RYOBI 18V system.

Frequently asked questions
Which battery voltage offers more power for larger yards?
Higher voltage systems generally provide more power for demanding tasks. The Greenworks 60V models and EGO Power+ 56V mower deliver robust performance for large or uneven lawns. In contrast, the RYOBI 18V options are better suited for small, flat areas where high torque is less critical. Choose a higher voltage if you need to handle thick grass or slopes.
Can I use my existing RYOBI 18V batteries with these alternatives?
Yes, several RYOBI models are compatible with the 18V ONE+ ecosystem. The RYOBI 33cm Mulching Mower, the 37cm Brushless Mower, and the 18V Hybrid model all accept standard 18V batteries. This allows you to reuse your current battery packs without purchasing new ones. Other brands like Greenworks and EGO use different voltage systems and require their specific batteries.
Which mower is best for self-propelled ease on slopes?
The Greenworks 60V 21-Inch Self-Propelled Mower and the EGO Power+ 21-Inch model are ideal for slopes. Both feature self-propelled drive types that reduce physical effort. The Greenworks option includes a brushless motor and handles up to three-quarters of an acre. The EGO model offers variable speed control, allowing you to adjust pace to match terrain difficulty.
Is there a compact option for tight storage spaces?
The Greenworks 40V 14-Inch Cordless Push Mower is designed for compact storage. Its narrow 14-inch cutting width and lightweight build make it easy to maneuver and store in small sheds. It weighs 33.3 pounds and fits users who prioritize space efficiency over wide cutting decks. This model is practical for very small yards with limited storage room.
Do any models offer mulching and bagging functions?
Yes, several models provide multiple discharge options. The Greenworks 60V 17-Inch Push Mower supports mulching, bagging, and side discharge functions. It offers versatile handling for small lawns. The RYOBI 33cm and 37cm models focus primarily on mulching. If you need to collect clippings in a bag, the Greenworks 60V 17-inch model is the most functional choice among the listed options.
Which mower has the widest cutting deck?
The RYOBI 18V 33cm Mulching Lawnmower has the widest cutting width at 33 cm, which converts to 28 inches. This wide deck covers more ground per pass compared to other models. The Greenworks 60V 21-Inch and EGO 21-Inch mowers both feature 21-inch decks. The smaller Greenworks 17-inch and 14-inch models are narrower and better for tight spaces.
Are brushless motors included in these battery mowers?
Some models feature brushless motors for improved efficiency and longevity. The RYOBI 18V 37cm Brushless Mower and the Greenworks 60V 21-Inch Self-Propelled Mower both include this technology. The Greenworks 60V 17-Inch model also uses a brushless motor. Other models, such as the standard RYOBI 18V 33cm and 40V Greenworks, do not specify brushless motors in their data.
Can the RYOBI Hybrid model run on corded power?
Yes, the RYOBI 18V Hybrid Lawnmower 37 cm offers dual power options. It can operate using 18V batteries or connect to a standard electrical cord. This flexibility allows you to mow without worrying about battery charge levels. It is a practical choice for small lawns where you want the option to switch between battery and corded power sources.
