TWO WAY TOOL: This tool works on my Craftsman DYT 4000 - 24 HP Intek. The sketch can be revised to fit your mower. Originally developed to help pull the flywhweel (100 ft lbs), it morphed into a blade removal aid. The red head is off a bent T post. If the SK is hard to read I'll scan it. Let me know. No fiddling adjustment is required to remove or install blades.
