Dave,
It doesn't auto speed, but there are 5 settings. I switched to level 3 when in the tree and then 2 after it is clear of the climber. Level one is more for loading wood or bringing the boom in and out in between pics. I say this like I've done it hundreds of times? /forum/images/graemlins/confused.gif
We have three of us that could take the truck out and run it with success. Since it was my creation I took the first role of learning the ins and outs before I hand it over to the other guys. They're more than capable.
Anyway, I would agree with Mangoes about the primary obligation is to your crew and working on their future. We've been pretty successful there so it's now on to the fleet!
