Re: Can someone explain \"Blade Tip Speed\" please
</font><font color="blue" class="small">( <font color="blue"> Tip Speed being greater, this would make the KK mower the best cut of anyone. Is this correct? </font>
We find a higher quill bearing/housing failure rate in mowers with the highest BTS. --Ken Sweet )</font>
Blade wear is another consideration. Running at full RPM, the blades on my 72" Woods really get dull fast. After a 7 acre job, they have long since quit cutting and rely on pure velocity to explode the grass like a Weedeater string. Backing the 540 RPM down to ~450, my blades stay very sharp for 1-2 cuts of my 7 acres of grass and light weeds, and leave a great finish. (It runs much quieter too!) It takes 5 minutes to do a light touch-up sharpening on the machine.
If you're cutting 1-3" brush, I guess you need all the tip speed you can get.
