Just got over a hundred hours on the tractor and bought all the filters and oil. I glanced at the drain plug and it's an allen head bigger than a 3/8ths inch. I'm not near the owners manual or the tractor which is 100 miles north at the in-laws, so what size is the allen needed for the drain plug?? I plan to get a 3/8 drive set and want to make sure whether it should be metric or english.
