Got the link to the build? Might be useful to the OP. Having the aux powerpack would be putting you in the category of the high-flow hydraulics.
An FEL mounted blower would certainly be more convenient than a conventional front mount for someone like me that uses the bucket/forks/snowblade alot. One of the reasons I got the tractor I did is I didn't want to pay for the mid pto I'd never use. Once I get chains on all 4, I'm going to try to convince my dealer to let me demo a pull type. They're awesome on a 100hp, not sure about my 33hp though.
