Need some help as we got 8"+ of snow today and I need to clear the drive. When I try engaging the PTO for the snow blower, it stalls the engine. I had an issue early this week where the thing would not start, changed the seat safety switch and that fixed that, but now this problem. Any ideas on where to start troubleshooting? It seems that the PTO engages as the blower starts to turn but then the engine dies right away. Haven't had a chance to look any further as the temp was around zero. Also, if anyone has a wiring diagram for this model, that would be helpful also. Thanks.
