We just put a new BX42 chipper on our Kioti 35 hp and it chipped great for the first hour in the 540 PTO and 2800 rpm engaging at low rpms to start. Then the shear bolt in the PTO went with nothing unusual going through the chipper and the PTO shaft level. Two questions if anyone can help me. Is a standard 50 mm 8.8 bolt the same as the 50 mm 8.8 shear pin bolt that fell out? They look and feel very different and I can't find anything on the web about this. The shear pin bolt is marked SC 8.8 and the standard bolt is marked 8.8 with a small triangle under it. Also, since the chipper is designed for 18 to 45 hp tractors and mine is 35 could I safely move up to a 9.8 or 10.9 shear pin bolt? Thanks
