Center mower blade keeps coming loose!
Hey guys. Deutz allis 1920 with 60" deck. The center blade keeps coming loose (during heavy use, leaves, rocks etc, not during normal mowing) but the others don't seem to have this issue. Clearly it was an issue with the previous owner too, judging by the condition of the centering washer. (I had to replace it). Is this an issue with these? I did everything I could think of. Made sure the blade is balanced. Bolt was tight. Even added a lock washer. Saturday it happened again. I have now put it on with blue loctite and I guess we will see what happens. Any clues?
