I tried to find that John Deere JDM J 25C or JDM J13E4 grease here but couldnĀ“t find it anywhere. Instead I found SKF LGEV2 grease which is especially ment for: "Extremely suitable for lubricating large sized spherical roller bearings subject to high loads and slow rotations, a situation where microslip is likely to occur. Extremely mechanically stable providing good water resistance and corrosion protection." And this grease is easy to reach allmost in any store in this sector.
