Haven't sheared one in years so when it popped I wasn't surprised, figured it wore in two. Snapped another one an hour later. It broke just as the clutch was being let out after backing up. Only thing that's changed is the tractor, instead of the old 2N I'm using an 885 David Brown. Grass and weeds is all that was being cut, no rocks or stumps.
Could the increase in torque and maybe unintentionally repeatedly disengaging/reengaging the pto clutch be the issue. I frequently forget that the clutch pedal only needs to be depressed a small distance to disengage power to the wheels versus the Ford. Figuring it was me I cut the head lands being careful with the clutch pedal then set the hand throttle and did nothing but turn the steering wheel and raise and lower the bush hog. Shear bolt lasted until the job was done an hour later.
What do you think, do I need a softer touch or is there something I need to do different now that I am using a real tractor?
