After owning my 3215 HST almost two years now, I'm almost embaressed to admit I recently found it has a quick dump feature with the FEL. The diagrams are right there on the FEL. I always new that if you pushed the joystick control all the way forward you can get the bucket to float. But the other day I noticed the diagram showing that if you push your joystick farther to the right, you get a faster dump speed. The only note I have on this is that the diagram is misleading. I actually get the fast dump mode when I push the joystick slightly to the right. It slows if you push it farther to the right. Was wondering if this is the case with other 3215 owners?
