Great machine! Used one for 15 years. Unstoppable with tire chains.

Cranman, Any recent progress to report?

This machine has that spring loaded pulley called the Power Boost...and as I was spinning the modified impeller, you could see the pulley kicking down a gear to give the impeller extra torque because of the extra load due to the tight rubber not completely broken in....I'm a convert!

I snapped off a piece of the rear pulley half while messing around to see how it worked.......Just waiting for that half to arrive so I can add a new belt and button it up. I'm dying to see how this throws with the Powerboost pulley...I may throw a spare 12 hp OHV Tec on it and make it part of the permanent herd if I'm really impressed. I never thought I'd find a blower that impressed me as much as the 924 Ariens....
