Hey Pj, just wondering. Why hasn't blade tip speed really increased in the past several years? It seems horsepower keeps going up as well as ground speed. One would think blade tip speed would also increase proportionately as well. It appears the industry standard is around the mid-18,000's. That is obviously "smokin" but as our ground speeds increase, blade tip speed needs to increase to keep up. Is it the spindle capacity or PTO abilities? I don't have a clue. Hustler has obviously set the bar for ztr ground speed. This appears to be the next step.
