Which one should you choose?
Choose Makita 21" Brushless Self-Propelled Lawn Mower if
- You already own 18V LXT batteries and want to use up to four for extended runtime.
- You prefer a mower with a confirmed commercial-grade steel deck.
- You need variable speed control between 1.5 and 3 MPH.
Choose Makita 40V Max XGT 21-Inch Self-Propelled Mower if
- You are invested in the 40V MAX XGT battery platform.
- You want a newer generation brushless motor system.
- You prefer a single-battery workflow over a dual-battery setup.
Verdict: The XML08Z is the better choice if you already have LXT batteries and need the flexibility of a four-bay system for long jobs. The 40V MAX XGT model suits users who prefer the newer single-battery XGT platform.

36V vs 40V XGT Mower Specs
Voltage platform
The Makita XML08Z operates on a 36V system, which Makita describes as 18V x 2. It uses two 18V LXT batteries. This model supports a four-bay battery system. You can insert two additional batteries for extended run time. The Makita 40V MAX XGT uses a 40V platform. This is a single 40V battery system. The voltage difference defines the power architecture. You must use compatible batteries for each specific platform. The 36V setup allows for more battery slots. The 40V setup relies on higher capacity single batteries.
Cutting width
Both mowers feature a 21-inch cutting width. The Makita XML08Z lists a 21-inch deck. The Makita 40V MAX XGT also lists a 21-inch cutting width. This dimension determines how much grass you cut in one pass. The width is identical for both models. This means you will cover the same area per pass with either mower. The choice between them does not depend on cutting width. Both are suitable for similar lawn sizes based on this metric alone.
Deck material
The Makita XML08Z has a commercial-grade steel deck. This material is listed in its key specifications. Steel decks are known for durability and weight. The Makita 40V MAX XGT does not list its deck material in the provided data. You cannot confirm if it is steel, composite, or another material. If you prioritize a known steel construction, the XML08Z is the clear choice. The lack of data for the 40V model leaves this aspect uncertain for that unit.
Drive speed
The Makita XML08Z offers variable self-propelled speed. The speed ranges from 1.5 MPH to 3 MPH. This allows you to adjust the walking pace to your comfort. The Makita 40V MAX XGT is also self-propelled. However, the data does not list its drive speed range. You do not know if it is variable or fixed. If adjustable speed is important to you, the XML08Z provides that specification. The 40V model leaves this detail unconfirmed in the current data.
Battery compatibility
The Makita XML08Z uses the 18V LXT battery system. It requires two batteries to operate. You can add two more for longer mowing sessions. This uses the existing Makita 18V LXT ecosystem. The Makita 40V MAX XGT uses the 40V MAX XGT battery system. These batteries are not compatible with the 18V LXT line. You need specific 40V batteries for this mower. If you already own 18V LXT batteries, the XML08Z is more compatible. The 40V system requires separate investment.
Motor type
Both mowers use brushless motors. The Makita XML08Z specifies a brushless motor. The Makita 40V MAX XGT also specifies a brushless motor. Brushless motors offer better efficiency and longer life. They require less maintenance than brushed motors. This feature is identical for both products. You get the same motor technology regardless of your choice. This spec does not help you distinguish between the two models.
Which Makita mower fits your lawn
Users needing extended runtime with 4-bay support
The XML08Z features a four-bay battery system. You can insert two additional 18V LXT batteries for extended run time. This setup supports longer mowing sessions on larger lawns. The self-propelled drive offers variable speed control from 1.5 to 3 MPH. This helps you maintain a consistent pace across varied terrain without excessive effort.
Professionals preferring the newer 40V XGT platform
This model runs on the 40V MAX XGT system. It delivers power through a brushless motor for efficient operation. The self-propelled drive assists with movement across the yard. The 21-inch cutting width handles standard residential strips efficiently. Choosing the XGT platform aligns with Makita’s newer commercial-grade ecosystem for future tool compatibility.
Those wanting a steel deck for durability
The XML08Z includes a commercial-grade steel deck. Steel construction offers robust protection against impacts from debris. The 21-inch cutting width provides a balanced mowing path. Variable speed self-propulsion allows you to adjust to your walking pace. This combination of durable materials and adjustable drive ensures reliable performance for regular maintenance tasks.
