Great flowable grease.. John Deere Corn Head grease. inexpensive and easy to get.
been a popular grease for brush cutter gear boxes.
I've been running 80-90 in my tillers for many many years, I've never had even one problem...
I've got aprox 2,000 acres on one of my tillers, that should be a good enough test!!

I've never seen one up close, so I had no idea... I guess I assumed all of them were sealed up good enough to use 80-90...That is pretty obvious. The 12 series are a low rent tiller with a name brand decal.
