Makita 36V vs 40V XGT Comparison
Voltage and Power
Voltage is the primary difference between these two Makita models. The 36V model operates at 36 volts, utilizing an 18V x2 system. This setup delivers a powerful motor that runs at 3,000 RPM, which helps cut grass faster. The 40V Max XGT model runs at 40 volts. This higher voltage platform is designed for commercial-grade performance and sustained power under heavy loads. While both are cordless, the 40V system generally offers more potential power output for demanding tasks compared to the 36V configuration.
Motor Technology
Motor type affects efficiency and maintenance. The 40V Max XGT mower features a brushless motor. Brushless motors are more efficient, generate less heat, and typically last longer because they lack carbon brushes that wear out over time. They also provide better control over speed and torque. The 36V model does not explicitly list a brushless motor in its key specifications. It highlights a powerful motor delivering 3,000 RPM but does not specify the internal technology. For users prioritizing long-term durability and efficiency, the brushless design is a clear advantage.
Runtime and Battery
Runtime depends on battery capacity and usage. The 36V model is sold with four 5.0Ah batteries, providing up to 40 minutes of run time. This configuration is substantial for residential mowing. The 40V Max XGT listing does not specify included battery capacity or runtime in the provided data. Without knowing the Ah rating or number of batteries included, direct runtime comparison is difficult. However, the 36V kit offers a complete package with known endurance, making it a practical choice for users who need immediate, measurable mowing time out of the box.
Drive System
Both mowers feature a self-propelled drive system, which reduces the physical effort required to push the mower. The 36V model offers variable speed control ranging from 1.5 MPH to 3 MPH. This allows you to adjust the walking speed to match your pace on different terrains. The 40V Max XGT model is also self-propelled but does not list variable speed settings in the provided specifications. It likely offers a fixed speed or different control mechanism. For users who want precise control over their walking speed, the variable speed feature on the 36V model is beneficial.
Cutting Width
Cutting width determines how much grass you cover in a single pass. Both the Makita 36V model and the 40V Max XGT model feature a 21-inch cutting width. This is a standard size that balances coverage area with maneuverability in typical residential yards. Since both products share this exact specification, there is no difference in the width of the swath they cut. This aspect is a tie, as both mowers offer identical performance in terms of how wide an area they clear at once.
Which Makita 21-Inch Mower Fits You
Users with existing Makita 18V LXT tools
This model uses four 18V LXT batteries to create a 36V system. You get up to 40 minutes of runtime with the included 5.0Ah packs. The rear-wheel drive offers variable speed control from 1.5 to 3 MPH. This setup provides better traction on slopes. It is ideal if you already own compatible batteries.
Professionals needing brushless motor efficiency
