Hi Norm,
I agree about the plastic height adjuster possibly going lower, but I wouldn�t think by too much. I would have to change the whole rear axle to try it, as the height adjuster handle won�t allow 8� wheels on the current axle - I learnt that before (different handles and I think it�s easier to change the whole axle than pop the clips off bits and pieces etc.). I might check the blade disks to see how far the blades mount from where the blade disk mounts up to the boss.
