Sudden Temporary Oil Loss

[smallfarm]

There is no sign of leaking into the bell housing and I checked the oil on the level. This tractors dip stick is straight and well centered does it reads the same at any rotation. Even if it was off I don’t see it making that large of a difference.
Hydraulic oil is at the proper level (yes I know it is impossible for the crankcase oil to leak into the hydraulics but I checked anyway)
Will change oil this weekend and compare volumes.

I have noticed on my after running for some time if you check oil right after shut down it may read low, but if you wait a few minutes it will read properly. Also sometimes oil will wick away from the dip stick when first inserted so it is best to wait a few seconds before checking and I also check it twice to get the same reading.
