I am looking for information on what the lever behind the oil filter is used for and I am gratefull for the information on this site.
Had one when I was a kid. 3spd transmission, but it had a lever on the rite side that was a step up which gave it 6 gears. My grandad had a patient for an implement towing device which was almost identical to the drawbars used today.
