I have a B1750 HST-D. I like to keep an eye on the level of the lubricants. The engine and the HST both have dipsticks, but the front axle does not. The owners manual and the Workshop manual both specify the capacity of the axle, but they do not mention how to check the level. The fill plug is located on the top of the axle tube, so I don't feel that the level needs to be at the bottom of the threads. Is there any specs that I'm not aware of?
