First weekly cut Super Z 72” I need help with a idea 💡

 This is the first time using the hustler super Z 72” on a normal cut. I’m still not 100% sure it’s gonna cut as good or close to as good as a 60 inch. Have you ever swapped pulleys to raise your blade speed? If so, I would like to hear your thoughts. I absolutely love the 72 inch cut. I haven’t leveled the deck yet. The motor rpm is 3600 so the motor is good. With a 24.5-inch blade spinning at 2,867 RPM: Radius (center of spindle to tip) = 24.5 ÷ 2 = 12.25 inches Radius in feet = 12.25 ÷ 12 = 1.0208 ft Tip speed: Circumference = 2 × π × 1.0208 = 6.414 ft/rev Tip speed = 6.414 × 2,867 = 18,390 ft/min Conversions: 18,390 ft/min 306.5 ft/sec 209 mph Pulley may be a hair below 9” now but not much. So a 8.5-8.75” pulley would get me to 19,000ft/min
