Yeah, I always wanted to run a groomer, but never thought I would have the time. Then I decided to take some time off from the "real world" and here I am. I am glad I did.
That is a BR350 with a winch. It is a new model, an update to the BR2000 (the silver cat in my pictures). It has a 350 hp Cat diesel and has lots of power and a great sound. We have four of them, two with a winch and two without. I've only got 15 min running one, not enough to get to learn the machine.
Winch cats are amazing. You can take full advantage of the cat's operating limits, climbing up and down really steep slopes. It is quite the sight to see a winch cat pushing a full blade of snow (with snow spilling over the top) up a slope you might have trouble walking up.
As for the color of the cats, I think Bombis are mostly yellow, but for the price you pay, you can get several different color choices. Vail decided on blue.
