38" deck with the Turbo collection system. Cannot seem to find a manual for the blower itself. Have one for the bags and mounts but not for the turbo blower. Also, previous owner said he bolted a wheel weight onto the left side of the deck opposite the blower to compensate for the lean caused by the heavy blower. When the deck is in the fully raised position it does lean to the right quite a bit, and levels out when I place the weight on the left side. But when I lower the deck to cutting levels and it is resting on the rollers, it is quite even. So I wonder why he did this. Didnt really get into it with him. All I can see is, it does make the deck less likely to hit an obstacle on the ground if it is hanging evenly in the raised position.
