I just bought the TORO 21" with the Kawassaki engine with the single bar and i am very unhappy with it. It mulches like **** and then i dont like the single bar. I am now thinkin of return it and either gettin a hi-vac snapper, exmark with teh BBC, or the snapper with the rear bagger. I really wanted 2 get the rear bagger because it dosent plug ^ as much as the commercial slide on the snapper hi-vac. what do you think i should go with, the snapper hi vac, snapper rear bagger, or the exmark with teh BBC????
