I made a dipstick for mine I use in the fill port. I will have to see if I have a picture or take one and write that up. With the tractor level in the garage and level in sight glass, I took a piece of about 1/8 rod that i mounted in a file handle. A piece of broom handle would probably work for a handle. It sticks down in with the handle stopping where the fill hole is smaller. Then I took a file and marked that spot. So if I am back there filling I just keep checking.
I verify when I am done with the sight glass.
Non of this maneuvering you pictured for me.

Note it was a piece of 3/16" rod. The full file mark is just above that bulge are in the scrap rod at 9-5/16ths from the handle I was going to try and catch it when it was low and figure out some amount needed to add to bring to full and mark that.
It tilts slightly going in towards vertical, not exactly at the angle of the opening.
It could be made to rest on the outside flat this rest inside at the bottom of the fill port.
Dimensions would need to be changed.
And that odd little z shaped pc is to hang it on the 5 gal pail so I don't misplace it.
This is a L2501DT so I don't know if it will be the same for a HST or other HP models in that same frame size. Also don't know if your location for fill is the same.
