I took delivery of 2002 TC40DA SS several months ago. I bought the lincoln rechargable grease gun and hit the loader zerks every time out and the others I can see often enough I think. I did not get a manual with it and wondered if I'm missing zerks underneath that I'm not aware of. I can easily get under tractor on concrete floor of new storage building if I know what I'm searching for. Any help would be appreciated.
