ABSTRACT:
A bearing assembly housing having at least one pair of spaced-apart bearing races surrounding a heavy duty drive shaft of a commercial lawn mower is provided with a critically located single grease fitting for introducing a lubricant to the housing to thereby allow the lubricant to enter at the top of the upper bearing race and migrate by force of gravity to the lowermost bearing race, thereby insuring sufficient lubrication of all the bearings in the housing.
