the lenght and width of the bolt is not what does the job, if the bolt is to small a diameter it will fail quicker from the slop in the implement, get the same size bolt that broke,, so it fits snug in the yoke,and put a nut on it, most people use a grade 2 which is a soft metal, grade 5 is stronger, and grade 8 has lots of strength so it will not break, what you are looking for is something to "shear" when it hits an obstacle. if you are not sure of grade ask the person for help, grade 8 is sometimes blue, but will have I think 5 slant marks on them, grade 5 will have 3 slants and 2 will have none as far as I remenber,,I have a 6foot hog I run behind my tn55 and grade 2 just snap as soon as I hit a ant hill, I have to use a 5, but I wouldnt go any stronger than that,, starrt with 2 buy a few 5's,, they all use the same nuts,hope this helps some,
