I serviced my ZD21 today and found something interesting. I changed the transmission fluid, including both rear axle gear casings (L/R). The WSM states "To check the oil level,draw out the dipstick,wipe it clean, replace it, and draw it out again".
What they don't explain is whether you should screw the dipsticks in fully to check the levels. There is quite a bit of thread (especially in the axle cases) and it must make a difference in the reading. For example my JD tractor manual clearly states that you should wipe the dipstick and then set it in the hole on its threads. It should not be screwed in. Now I don't have the owner's manual and maybe it is explained there, but I would appreciate it if someone could tell me the right way to do it. Thanks!
