Welcome to MLMF. Most everything you'll need to know about this tractor, or any piece of power equipment, can be found in the operator's manual. for some reason those things often go missing, especially if the equipment was bought used from a private party.
I took a look around a bit, and found this. Maybe there is some helpful information for you here.
