well awesome job if you did accomplish that while it was still on the machine.
either way, on or off the machine it is still rather tedious doing that.
Those masts were always troublesome to deal with but i'm glad you got it done. (yep those clearances are tight in those for sure).
i mentioned that it may have been a cascade mast but i think they were bought out by another company, i think they changed the name to Lift-Tek or something like that. I think cascade is still the parent company but they developed a new division called Lift Technologies i think. In either case the new masts will be tagged Lift-Tek i'm pretty sure.
When it comes to the high lift masts that are 4 or 5 channels these guys are the ones that make them i'm pretty sure.
anywho, glad you got it done (without injury) ;o)
