Doug, You can open Manuals? All the way in to pages?
I log in as Guest user
go to Browse, click on Browse Books
click on Massey Ferguson
click on Parts Books
click on Grounds care Equipment
click on Lawn tractors / Mowers / Mower decks
click on 10 tractor or whatever model
Then click on sub section and you get the exploded view with list of part numbers.
that's how I've always done it
On Tuesday I couldn't get in when I got to the stage where the Massey Ferguson name shows it wasn't there.
