Hesston 1320 mower/conditioner

[Toddwp]

Does anyone one know how much gear oil a Hesston 1320 mower/conditioner uses in the bar?

Well, I searched "Hesston 1320", and the very first thing that came up was a YouTube video showing how to change the oil in one, and the guy says "2 quarts, some say two and a half".

I saw that as well, but I found some saying 5-6 also

The factory fill was 3.5 lbs which equates to about 1.9 quarts. For field replacement the quantity is 1.75 quarts since it is impossible to get it all drained out. It is critical that it is not overfilled because that will cause excessive heat buildup. It's better to be a tad low that overfull.
