Warranty	2 Years	Average	6% worse	Standard industry backing. This 2-year window is the baseline for most reputable residential gas mower brands.
Cutting Height Adjustment	6 settings	Average	3% worse	Standard residential precision. Provides enough versatility to handle everything from low spring cuts to tall summer maintenance.
