Got delivery on my 1026R in late summer. It came with an "Issue A1" operators manual (paper). The Deere site now has an "Issue D1" version, with several substantive changes.
Perhaps most importantly, one needs it for the 50-hour service interval, in that D1 shows how to pull and clean the Transmission Suction Screen. I found out the hard way that the paper copy A1 version did not do so, after I had already drained the transmission oil for the 50-hour change!
I guess it is best to check back to the Deere product support site regularly, for the latest version of the manuals... lesson learned.
