Thank you for contacting the AnswerARMY.
If you have never purchased the mulching kit I suggest that you start with that as it will include blades and cover.
There is the possibility that the blades you have are mulch capable, different retailers may purchase different specifications of the mower thereby having different blades as standard equipment on the same model tractor. With out knowing which blade you have I can not answer which you need kit or cover, so to be safe I always recommend the kit.
