I just got the new tractor a few weeks ago the book says not to fast or to slow or any steady speeds .Other people says hook to something and pull it like your going to run it .I guess after the 50hr of somewhat taking it easy i thougt i would hook it to something like a mower or bushhog and run it hard for a day or two .The thing is i use it on the road from job to job and i dont like to run it to much without some sort of load on the engine.Any tips?
