You did not indicate the model number of your tractor. It appears that this mulch kit is only designed for Craftsman models 917.28033 and 917.28035. If you have one of these models, the mulch kit instructions should be correct. I do not have a copy of the mulch kit instructions available. If you are having trouble attaching the mulch kit to one of these tractor models, then I recommend that you resubmit your question with details about the problems that you are having. If you do not have one of these models, resubmit your question with the tractor model that you have and we will research the mulch kit to see if it is compatible or whether the tractor needs a different kit.
