Greasing Hustler front axles

[Greenleaf]

Looking for advise on how much grease to put in my 2014 Hustler Fastrak front axles.
Should I continue to pump grease until it begins to bleed out the sides? Or is there another way of knowing the axles are suffuintly greased.

Grease till you see grease come out then 2 or 3 pumps every time you mow for every zirk.
