My 2 cents worth. Vicon refers to the torque converters. Some vicon machines had one 379 Cat engine that where connected to two Variable Control (Vicon) torque converters through a Lovejoy coupler. Although the operator is obviously 'green' the valves in the controls may not have been serviced properly. I know a lot of mechanics that don't properly bench test the controls when they rebuild them because they haven't been shown how to set the internal valves that say "do not adjust" .
@ trackhoe. On a 4600 equipped w/Vicon there are two separate engines. One for the drums and one for swing. The throttles are air actuated by the position of the hoist, drag, or swing levers. That is, the operator pulls back the lever, the first movement engages the clutch, then further movement progressively throttles up the engine. It gives it smooth control.
I am aware of what Vicon is. I was referring to when he was pulling the bucket through the cut from 2:22- 2:55 and 3:40- 4:15 and every other time he was cutting. It seems to me that the exact same result could have been gotten by using steady half throttle rather than alternating between idle and full. It would have meant slightly less wear and tear on the machine and saved a little fuel. Of course, not having been there to see, maybe there was a reason for it that I couldn't see in the video.

I couldn't finish watching it. The operator's constant up and down with the throttle drove me nuts.

I agree! terrible operator...must have been first time

Sounds like the 4600 has Vicon.
