A while back, I was asking questions about the Raleigh rod-brake roadsters. One of the owners of one commented that riding it was "like pedaling a tractor". So maybe that would be the bike to start with for full effect. (Realistically, I think a Worksman industrial bike would be a better candidate for JD treatment!)

As to JD merchandise- I think they sold their logo to anyone that would use it for anything. There's probably JD toilet plungers out there somewhere.
