I got my Ultra Vac put on my Laser yesterday and tried it out today. WOW!!! Its nice and bags great. I was running over huge piles of leaves and it was grinding them into nothing. Bags get packed with just shreaded leaves and grass. The double Blades help too!! Front end is a lot lighter now, makes hills a little interesting. Takes up some trailer space too, other than that, I highly recommend it. Easy to take on and off the laser. I think its worth the money and it beats raking!!! Price is $1200.
