i have the above mentioned blower attached to my 2135 cub, and when i engage the pto, the belt slips off of the idler pulley and wedges itself between the pulley and it's arm, which starts to stall the engine/burn the belt.
it's a new belt, and what i've noticed is that the idler pulley, along with the tandem, blower/auger pulleys are not in alignment
/horizontal with the belt. in the factory? mounts, they're all tipped 'backward' a few degrees from vertical.
the local cub dealer shows no bulletins from cub, and has no suggestions

anyone have a suggestion?
