That's also my desire. I don't want to get into specially built motors
so forth. But I also don't want to buy them from RS, I just checked my
catalogue and the prices are high enough to make your hair fall out at
fifty paces :-(

All my previous research has shown that the best way is with a high
speed blade. The grass blades are very flexible, and they just bend over
unless struck with enough force. I also believe that the grass tends to
stand up due to the sucking of air past the mower blades, this greatly
improves the effect.
