Blade tip speed Page 2 LawnSite™ is the largest and ...

Mar 28, 2008  High blade tip speed increases air flow, but more importantly it increases impact energy of the mower blade hitting the grass blade. Impact energy increases approximately proportional to the square of velocity, so a blade tip with a speed of 19,000 fpm would have 41% greater cutting impact than a 16,000 fpm blade tip (kenetic energy KE=1/2mv^2, so ratio of KE=v1^2/v2^2).

Blade speed Lawn Mower Forum

Aug 01, 2021  But for the most part blade tip speed is only critical on push mowers where the longer the blade length the slower the engine has to run to avoid exceeding that limit. On riders and such the belt and pulley system limits the speed to safe limits, and the operating speed of the engine is basically fixed around 3600 rpm.

Jun 20, 2016  Up to a point, yes you'll get a better cut with higher blade tip speeds. It also allows the mower to physically move at faster speeds-some commercial zero turns have a tip speed of over 18,000 fpm and grounds speeds of up to 15 mph. Deck design/durability and bearing quality also have to be able to handle the higher blade speeds and the amount of debris being discharged.
