hi guys I went to add grease to the deck Mandrel zerks on my 2012 gt6000. I was adding grease and not sure when you know it's loaded. I mean, I couldn't see anywhere where the grease would ooze-out indicting theyre full. I looked around the pulleys, all around the mandrel housing, and under the deck and couldn't see anything. I just gave a good ten pumps on the gun and figured it was ok. any advice. thx.
