I have the 7000 and while some of the things I've heard about earlier Cat clutches had me a little afraid, I LOVE the Cat clutches. Easy maintenance, good belt life, and low engagement! I had a Nytro and anyone that's ridden one of those knows what they are like to ride around the yard/parking lots. The only issue is the belts are more expensive. And on this forum I continually see people asking about a soft start spring. If you can make it work, go for it!
