The Winnowl Lab Report
| Specification | Value | Rating | Vs. Average | Winnowl Insight |
|---|---|---|---|---|
| Total Run Time | 60 minutes | Strong | 45% better | Extended-range endurance. Provides a necessary safety buffer for thick turf or properties that push the limits of standard battery tech. |
| Battery Capacity | 6 Ah | Exceptional | 44% better | |
| Warranty | 5 Years | Exceptional | 69% better | Premium support level. A 4 to 6-year window signals high manufacturer confidence in the build quality and component lifespan. |

| Cutting Width | 20 inches | Strong | 21% better | |
| Number of Batteries | 1 count | Average | 31% worse | Single-pack baseline. This is the entry point for cordless mowers, providing no hot-swap capability for larger jobs. |
| Cutting Height Adjustment | 6 settings | Average | 6% better | Standard precision. Offers enough variety to handle the transition from spring growth to summer dormancy. |
| Battery Voltage | 40 V | Average | 2% better | Standard residential output. This range represents the industry sweet spot for balancing battery weight with reliable cutting torque. |
