We've been testing a Pisten Bully 600 active boom winch groomer on site for the past week and it has performed very well. We currently have a PB 600 winch machine without the active boom feature. This new advance in winch technology supports steering of the tractor under the winch by applying hydraulic pressure to the turret of the winch thus applying down force proportionally to each drive track from the operator steering controls. This allows the machine to push and groom snow uphill effectively off the center line of the winch cable anchor point getting better cover in “hard to reach" spots. The Boom was put through its paces on Tuesday night, Jan 15th on Falcon and wow, what a job it did on the steep headwall pushing out the mounds and spreading nice, soft snow over the slope.
