I know that the blade tip speed is limited by ANSI to 19000 FPM. Which, on a 22" blade, equates to 3299RPM according to my calculator. I recently bought a tachometer, and found that my residential push mower, with a 22" blade, is running at 2750 RPM. So I started increasing it. When I got to 2950, it seemed like it was running really fast, and had a lot of vibration. So I backed it down to 2900, and the vibrations seem to get better. So my question is, of course, what speed should I set my engine to?
Engine: Briggs 128T05-5123-B.
Mower: 2011 Toro Recycler w/Personal Pace.
I still have the owner's manual and the engine manual. Neither mention engine RPM settings.
Not sure if this is the right forum, but the only other blade tip speed discussion I could find was in this forum.
