The power really wasn't an issue, it worked really good and noticeable improvement over standard Blackhawk. I put a lot of it on it being a prototype still and we were working through the app issues and fittings.
I prefer the Fecon Blackhawk Fusion. But if you are in the north or the Midwest then a Diamond Belt Drive disc mulcher might be a great purchase for you. Just depends on how you are going to deploy it and what finish quality you need. Drum is higher finish quality but disc should have lower operating costs.
