I am 200 miles away from my new tractor and there are many things I did not have time to look at in the 5 hours I initially played with it! I am pulling a trailer full of building supplies this next trip up. I may not be able to make it up the dirt drive way (steep incline) with the trailer if it is rain soaked. I will drop the trailer on the road and use the tractor to pull it up. I never closely looked at the draw bar so I need to know what size shank I would need on the 2" hitch ball. I am figuring 3/4" but I'm not sure. Owners manual does not show hole sizes. 3/4" or 1" I am thinking....just want to be prepared! Any help appreciated.
