Joe,
Here is a link to the NYS form MV-529 detailing all vehicle equipment requirements (including emissions) to properly register a vehicle in NYS.

Ray,
Thanks for the tip on "weberizing" my new John Deere! I think I will pass for now :-) I would like to see some IDA webers on the SPF, but the $$$ for that are gone, for now!
Joe, hope this helps,
Jim Kellogg
