Searching for and EP (excessive pressure) gear oil. The only gear oil I have found that states EP is Harvest King Brand. The Kubota 80-90 does state it's the recommened EP.
Anyone use an alternative labeled EP?

Extreme Pressure (EP) gear oil has been the standard for automotive drive axles and gear boxes for over a century. There are hundreds of brands and its sold by automotive parts stores everywhere. Look for API service GL4 or GL5 on the label. The Harvest King product is as good as any in your application.
