No big deal but getting a good read on my hydraulic dip stick has always been a bit of a mystery to me. If my tractor has been sitting a long time I can pull it out and there may not be anything on the stick. I can put it back in and one side might show at the add mark and the other side about half way up between the two marks. No matter how many times I put it back in and out it will show the same. What am I to believe? Any suggestions for an old man?
