Hi,
Neither tractor have anywhere to put the dipstick, and not too sure where I would install one either.
Gearbox has two plugs, 920 has them on the left, and 900 has them on the right. I am assuming bottom one is a drain, and the higher plug is a level check? In addition the plug on the top accessible from inside the cabin, must be the filling point.
Does this sound correct?
Can anyone confirm this?
