Makita 21-Inch vs 18-Inch Specs
Cutting width
The Makita 36V 21-Inch Self-Propelled Lawn Mower offers a 21-inch cutting path. This wider deck covers more ground per pass, which helps you finish larger lawns faster. The Makita 18-Inch 36V Self-Propelled Lawn Mower provides an 18-inch cutting width. While narrower, this size offers better maneuverability around tight obstacles and smaller yards. If you have a wide-open lawn, the 21-inch model covers area more efficiently. For tighter spaces, the 18-inch width is easier to control.
Battery capacity
The Makita 36V 21-Inch Self-Propelled Lawn Mower comes with four LXT 5.0Ah batteries included in the kit. This specific capacity supports up to 40 minutes of run time. The Makita 18-Inch 36V Self-Propelled Lawn Mower is sold as a tool only, meaning it does not include batteries. You must purchase batteries separately. If you already own compatible Makita batteries, the 18-inch model is a better value. If you need a complete package with high-capacity batteries, the 21-inch model provides the necessary runtime out of the box.
Motor type
The Makita 18-Inch 36V Self-Propelled Lawn Mower features a brushless motor. Brushless motors generally offer longer life, increased power, and better efficiency compared to brushed motors. The Makita 36V 21-Inch Self-Propelled Lawn Mower lists a powerful motor delivering 3,000 RPM but does not specify if it is brushless. The brushless technology in the 18-inch model suggests potentially better long-term durability and maintenance-free operation. This is a key technical advantage for users prioritizing motor longevity.
Deck material
The Makita 18-Inch 36V Self-Propelled Lawn Mower is built with a commercial-grade steel deck. This material is designed for durability and resistance to impacts, making it suitable for heavy-duty use. The Makita 36V 21-Inch Self-Propelled Lawn Mower does not specify its deck material in the provided data. If you mow over rough terrain with rocks or debris, the steel deck on the 18-inch model offers known resilience. The unspecified material on the 21-inch model leaves its durability characteristics less clear.
Dimensions
The Makita 36V 21-Inch Self-Propelled Lawn Mower measures 40.2 inches in width, 18.7 inches in height, and 24.4 inches in length. The Makita 18-Inch 36V Self-Propelled Lawn Mower measures 22 inches in width, 20.4 inches in height, and 37.4 inches in length. The 21-inch model is wider but shorter in overall length. The 18-inch model is narrower but significantly longer. These dimensions affect storage space and transport. Consider your garage or shed dimensions to ensure either model fits comfortably.
Which Makita Mower Fits Your Yard

Homeowners wanting a complete out-of-box solution
You receive a full kit with four batteries, so you do not need to purchase power sources separately. The 21-inch deck speeds up mowing for average-sized properties.
