CRAFTSMAN V20 BRUSHLESS RP 21 in Rear Wheel Driver Mower, 2 x 9Ah Batteries and 2 Chargers Included, Up to 70 Min of Runtime, Self-Propelled, LED Headlights, Dual Blades (CMCMWSP320X2)

What It Is

This is a complete CRAFTSMAN V20 BRUSHLESS RP 21-inch self-propelled mower package, not a blade accessory. It’s designed for residential lawn care, offering cordless operation with dual batteries and chargers for medium to large yards.

Fitment & Compatibility

• Deck size: 21-inch cutting deck – verify your yard’s terrain and grass type for optimal performance.
• Model: CMCMWSP320X2 is the specific package; this is the complete mower, so compatibility with existing tools is limited to CRAFTSMAN V20 battery system (2 x 9Ah batteries included).
• OEM vs aftermarket: This is OEM CRAFTSMAN product, not a replacement blade or accessory. If you need replacement blades, check for CRAFTSMAN 21-inch dual blade models (e.g., part #CMXGZAM190141).
• Measurements: Deck width is 21 inches; wheelbase and self-propelled system are proprietary. Ensure storage space for the mower (approx. 60 x 22 x 40 inches).

Key Things to Know

• Quality: Brushless motor and dual blades provide efficient cutting; 70-minute runtime is realistic with both 9Ah batteries on low-lift conditions.
• Installation difficulty: No assembly required for the mower itself (comes mostly pre-assembled). For blade replacement, use a socket wrench and block the blade to prevent rotation.
• Common gotchas: The self-propelled system is rear-wheel drive – works best on flat or gentle slopes, but may struggle on steep hills. Batteries are heavy (9Ah each), so charging takes 2+ hours per battery. LED headlights help in low light but are not bright enough for full darkness.
• Dual blades: One blade is for mulching, the other for bagging; swap as needed. Do not run both simultaneously.

Should You Buy It

Buy this if you want a complete, ready-to-use cordless mower package with long runtime and self-propulsion for a medium lawn (up to 1/3 acre). It’s ideal for CRAFTSMAN V20 users who can share batteries with other tools, but skip it if you need a budget option or have very hilly terrain.
