Not good. Firstly why so little and secondly why water.
The water was quickly explained by the filler plug having a small hole at the top, so whenever it rained or I washed the tractor, some water would've gotten in. According to diagrams there should be some metal breather springy thingy on top that I never noticed missing.
Should be easy to fix, somehow.
I decided to flush the mud out with some diesel, which promptly sprinkled back out from behind the left wheel, meaning the shaft seal was shot.
Wheel off, final drive open, yup, I'm gonna need a bigger gear puller, a seal and a bearing or two.
