I was reading on the Toro web site that the larger Toro snowblowers do not use any shear pins. The theory being the front drive case/gears are so strong that if you do pull something in that it will just stall out the motor. What do you all think of this? Good or bad? I feel I should mention I once drove over and pulled in a brick into my "94" Toro 1132 and it stalled right out without any damage at all but for a moment there I thought it bit the dust!
