When you went to start the run is 36" the most you can do without running into constraints?

If it is that is what I expect the plow to run all the way up the hill, especially on main runs I run my constraints as tight as humanly possible. 

Drop the plow in the hole where you want to start, keep inching up your minimum until it tells you it cant do it and then back off one inch... seems to work for us.
