2017 Deere 1023E with 68.7 hours (bought used, presumably oil was factory fill from several years ago, so wanted to change based on time, not hours).
Out- probably factory fill/break in oil
In- 1/2 quart Rotella T4 15w40, 2.5 quart Rotella T6 5w40, OEM filter.
The manufacturer does highly recommend break in oil for a minimum interval of 100 hours. Called the local dealer to see if they had any in stock but they were out. The rep on the phone said "put in some Rotella and call it a day".
