Help. I started to change the blades on my Z this weekend and realized my small shop air compressor does not have enough volume or pressure to break loose the nuts which I understand are torqued to over 100 #'s. I tried to break them loose with a 15/16' box end and hammer but did not not have any luck. I think if I could get a blade holder tool, I could get the right combination of leverage and position and break them loose. If not I will have to either go borrow a stronger compressor or load the mower up and take it to one. Does anyone know where I can get on of the blade holder tools? Thanks in advance.
