2009 Cub Cadet RZT 50 Deck pullys

[jfmorris59]

Is anyone aware of an aftermarket Deck pully that will fit my RZT50. I would like to go down in size to help increase blade tip speed. and to help in the grass discharge. When cutting the current set up has problems with grass discharge and sever clumping. I have gone to gator blades leveled, leveled and releveld the deck. Next to increasing the motor RPM I see no other option?
