The city of Minneapolis Forestry just got four articulated Avants. I don't know which model. I haven't driven one yet, we just finished planting season so it's only seen duty using the auger. We're just shifting into ash/elm removal season where they'll get a workout.
Real nice machines, that's about all I can tell ya. I've operated two different models and they both perform well. Lumberjack and TNT will have to fill in the details, but I can say that you won't be disappointed.
