Hello all. I am looking for advice from someone who is familiar with Tru-Cut homeowner series. I have an H20 and just installed a reel roller (replaces front caster wheels). When I lower the mower to its lowest cut setting, the bedknife hits the ground. The second setting is fine.

I know I can leave it as is and just remember not to use the first (lowest) setting, but I would really like to adjust it so that I can. Does anyone know what I need to adjust? Thanks in advance!
