I just got a SB84 for my DK50 tractor, and the shear bolts which came with it for the PTO to the gearbox are snapping like twigs. The manual says they are grade 2, with I would expect to break very easily. What grade are you guys with the same blower using? Grade 5? Grade 7? I was blowing champagne powder this morning and I went through about 10 shearbolts on that PTO to gearbox connection. It made it a serious pain in the butt and made the "blower" just about useless. I probably wouldn't get 2 feet in Sierra Cement with those stock bolts.
