Another thing to watch out for with these kinds of site is the possibility of malware imbedded in the PDFs. I'd say if Kubota is not putting them out there it's probably illegitimate and possibly dangerous. And now for my $0.02 - Kubota ought to provide the parts and operators manuals for free on PDF and only charge for WSM or paper copies of the others. My rationale is that the Operators manual is a factor in helping to ensure safety for owners who have lost theirs or acquires the tractor used - it's good for Kubota, good for the owner; and the parts manual is a no brainier - you're providing the customer with the knowledge needed to buy the right parts, and you do want to sell parts, don't you Kubota?
