Hi I took delivery of my Hustler Sport today and so far it runs great. I purchased the mulch kit and the dealer installed it prior to delivery. I've read a few posts about the variations in decks, and thus variations in mulching kits. It seems my kit only includes the chute plug. My dealer says this is correct. It seems odd that there is no longer any mulching blades/baffles included, but it still costs $159.99 just for the discharge plug. Am I getting accurate information? Thanks for your help.
