MTD push mower wheel repair - how to remove bolt from Height Adjustment Plate

Looks to me like a "carriage bolt". Remove the nut on the inside of the mower housing and the whole bolt will simply pull out of all the plates. Of course if it's rusted, a little oil and a hammer might be needed.

It's a shield bolt, ½"X.57", part no. 738-0507 Try going to an outdoor equipment company and inquire of one of their mechanics.

Kind of like the carriage bolt but designed so the "shield" or square part is of the correct length to accomodate the thickness of the plates and mower housing so tightening the nut won't make the wheel adjustment too tight to rotate. I see...I had never heard that term but I see where a " carriage" bolt wouldn't really work. But the thing is that the bolt is not suppose to turn like the OP was trying to do. He should be removing the nut on the inside of the housing.

Yes sir, I've accomplished removing the nut from the inside of the housing, for sure. The problem is the bolt won't pass back through the opening in the plate. I will take it down to the small engine shop to see if they can take care of it.

Thanks, Dave F

no dice. that sholder bolt is wedged in there like no manana.
