Yes back on the mulcher today after running it for about an hour on Friday afternoon. First impressions was that it is not an 160 hp woodchipper but when used with a bit of correct technique can get a bit done. I will update with some more pics and just created a new YouTube channel so can start sharing video here as well. The priority valve is a switch on the console that I hit and the mulcher starts running and I have full control of the diggers functions but the movements are a bit slower, when I flick the high flow switch I can not lift the boom up, I can slew, crowd and move the dipper arm a bit but only come down with the boom. I have not tried to see if I can get the high flow working without the priority valve but it is possible to just hit the button on the joystick to fire up the hammer piping as normal and use the mulcher without the priority valve just have to hold thumb down

You’ll not go wrong with an FAE, brilliant bits of kit.

 

I’m at a bit of a loss when you say Hi Flow, as generally the Priority Valve is dialled in for the machine and you’re good to go. It’s either on or off and when activated should provide about as good as you’ll get to the head leaving enough for the machine to function on.

 

There is a good explanation of a Priority Valve here and how it manages to balance the needs of the Cutting Head with the Machines need to be able to multi function.

 

There’s a good explanation of a Priority Valve I found, that may help guys understand what we’re going on about.
