I got to drive my first piston bully at the end of the day. Drove it down a ski run not being used back to the shop, all in maybe 2 miles. Very easy to drive, kinda like a big skid steer. Front plow is 12 way and easy to figure out. On the back end, not sure on the tiller and mats to make the corduroy. You set the depth of the tiller and apply up or down pressure to get perfect skiing. But that is all beyond me without some direction
We have a master groomer from Vail, he is good and runs the machine fluidly, and he doesn't beat up the machine.
One night after a good snow dump, I am going to go for a ride and see what I can learn. For now, I just get to maintain and fix them, and at best drive them to where I can repair them. We have 2 piston bully's, cummins powered, a Prenoth with a cat motor, ( Strong machine with big balls ) and a older Bombardier that has a nice 12 valve with zero smog crap on it, that machine will outlast all the new fangled tier 4 fancy smog compliant German groomers any day.
There has to be over 100 zerk points on these new machines, have to be greased every 8 hours. Don't think that has ever happened until I got here. Piston bully's seem to pop hydro hoses regularly as well, all I can think is the drivers are pushing the machinery too hard.
I will snap some pics of these things tomorrow. They can creep up some pretty steep terrain, enough to make you plan an exit out of the cab If things go sideways.
I think they top out at about 25 mph, but they normally troll along at about 10-15 mph. Tomorrow is day 19 straight without a day off, come Jan 2, a few days off to relax and do some laundry and hit up the grocery.
One more 16" dump and all runs should be open, good base now, and more snow coming over the next few days.
Look up Tucker snow cats, they are awesome, but not usually used for commercial grooming ski runs but they can go anywhere and are just bad ass.
Cheers from Eagle point.
