Have the 72" belly mower on the 2710--fairly loud, I plan to wear ear gear when doing the full lawn. Remember reading 80db for the tractor.
Suggest you look at the 72" deck--much easier to install/align than the 60". Both are covered in the same manual, and I've noted a few times already big apparent differences while reading through.
Not sure how intensively you'll use the tiller, but a lot of good used ones out there at reasonable prices. In the extreme, my neighbor came over and did my 1A garden the other day with his rusty $15, yes $15, auction special. As far as resale, he would have done well had he accepted my $50 offer--no luck!
Besst of luck.
