GT245 Question

Hey all,

This question is actually for a friend who owns a JD GT245. He currently has just the mower deck for it but was interested in some other attachments and wasn't sure if they're available, should there be any you avoid, etc.

So he told me he is interested in a tiller and a snow blade...

Are those usable on the GT245 and what entails using them and... well, the usual questions.

Any help is highly appreciated.

Happy Weekend folks,

Justin
