Re: Bush hog speed .
I figure 540 for really hard cutting, pretty much whatever you think is the worst the unit is designed for. For cutting grass and light brush, I run more like 2000rpm engine speed, where my 540 mark is about 2800 engine rpm. As long as it's cutting cleanly, the blade speed is fast enough for me. Just my opinion anyway.
