Trex 600NSP - Inner/Outer Mixer Arm Holes

[Richard H]

Some of the guys were talking about this last night but I didn't get to hear the whole conversation regarding the screw holes for the upper mixing arms on the 600. This is something I have never tried changing yet and mine are on the outer holes at the moment. What difference would putting them on the inner hole make and those of you with a 600 - which do you use?

Outer holes = More pitch and faster

Inner holes = Less pitch and softer setup.
