I can't find anywhere that has any pictures of the newer style John Deere catcher units. I'd like to see, in some detail, the 2 bag unit. How easy is it to remove/install the bags? Does the hood open easy? How well does the blower work/is it all metal inside now? Do the bags fill good even in wet grass? I'm thinking about a John Deere 54" machine, either the 727 or the new 820A. Other than 2 horsepower and a different body, what's the real difference between the 2? What the heck is the difference between the 7 Iron II deck and then 7 Iron Pro deck? I think I've reached my 20 questions limit of this post... I just can't get any good info from their site, and the dealer here won't know much more than that. Looking for some actual real world users to respond! Thanks!
