My J46 deck threw its center blade while mowing the other day. I don't know why this happened, because I removed the blades and sharpened them this spring, and torqued the bolts down well with new lock washers. Anyway, I tried to chase the now-damaged threads in the plate that the blade mounts to without success. The threads were too damaged and the bolts would not torque down, so I filled the holes with JB Weld and will drill and tap them tomorrow when the epoxy is cured.
I told that story in order to ask this question: I noticed that the blade mounting plates on all three spindles have a slight amount of "rocker" to them. That is to say, they are bent upwards at the outboard ends, so that a straight edge held against them will rock back and forth slightly. The gap seems to be consistent across all three plates. In the parts manual, they appear to be completely flat. Is this normal? When I refurbish this deck this winter, should I be concerned about this curvature enough to replace the spindles with new ones?
