Oil & Fuel B7100HST-D

[Ken]

Have a recent purchase of B7100HST-D and in checking the fluid level's .The hydraulic dip stick shows no level of fluid.
have looked all over and find no plug that can add fluid. on top of transmission is a level dip stick and to the left side is a large plug but unable to remove . the plug is a plug and when attempting to remove just breaks off fiber type material. in front of this as a inverted oil filter.
Now my question is where to add hydraulic to this tractor. Or suggestions on how to loosen this plug mentioned with out additional damage to plug.

That plus is not a plug it is threaded and must be unscrewed. Mine was quite tight when I bought it used. Gentle persuasion with a pair of channel lock pliers got it loose. Thai is the fill hole
