1/2 inch by 2 3/4 is the perfect shear bolt, but no one stocks it. So back to a 3inch bolt with lots of thread hanging out. I bump to to grade 5 or 3 marks on the bolt head. The grade 2 or 3 bolt is way too soft and will snap just hitting fire ant mounts and heavy weeds and very light brush. Even the black grade 5 will snap fairly often in brush but at least you can get by with about 10 bolts a day in clearing brush, and a couple of weeks on just grass and weeds. Every shredder tractor is sent out with a bag of 10 bolts and nuts along with two wrenches when we're shredding. (brush hogging) Tractor supply sells them by the pound vs the grade.. so I buy the black bolts... and the silver nuts and washers in separate bags so they can be weighed and priced correctly. The silver bolts sadly are probably from the land of not quite right... and therefore useless as shear bolts... from most stores today. I do not use the gold grade 8 bolts (five marks on the head) to prevent damage to my equipment. ymmv.

I dropped off the tractor expecting a transformation from a 6 volt to a 12 volt system utilizing the original generator housing, and a total rewiring of the whole tractor. The front end center pin bushing was worn also so I ask that they replace it if they had time. Well, that’s wha
