I have been using 0 grade grease for years, only reason it seems easer to get localy. most of my roller seals seem to leak and a little thicker seems to stay in better.

i switched to corn head grease. john deere AG dealer carries it in regular tubes. i have some rollers that won't hold any oil that flows but the corn head grease stays put and only flows when there is motion,so it stays when parked and only exits just enough when operating to keep dirt out. i use the same lube schedule as the book recommends.
Well I think it has a lot to do with what type of track rollers and their design. From the years of roller bearings to bronze bushings certain rollers seem to require different needs. Many types of grease is still available for purchase from the last 100 years. Greases and parts have improved over the years but sometimes the design and lessons of failures can help you pick the right grease you need. I still use the original type of grease on my Cat from the 20's it's certainly a different grease but still around today. The design of the bearings and their intended purpose is to move the grease but also to keep everything lubricated by the oils that are in the grease. Of course the newer the equipment gets the more easily it is to use more common greases today. I have never used corn head grease but when I was looking for grease it probably had more consistent properties to what I needed but never used it.
Chevron still makes the 00 track roller grease.
Around 2005, I was out in the Bradford PA area, an old Operator out there gave me some containers that was "Steam Head Grease". He told me that it was the closest available replacement. Wish I could remember the brand name that was on the box? It does flow in warm weather but barely flows in cold weather. Nice thing is, it doesn't leak out of worn out Rollers! Its not correct probably, just throwing it out there!
