I have a 32" metro which has two spacers below the spindle at this time. I'm wondering if there is an ideal amount of spacers which should be below the spindle to get the best cut/vacuum. I think I read somewhere that I should place all four below to get the best cut, but I would like to make sure. I can than adjust the caster spacers to get the required cutting height. Thanks. Also, I am looking to cut at a height of 2 1/2 inches (bluegrass/ryegrass). If anyone can give me the entire mower set up(spindle spacers, caster spacers, rear adjusment) for the best cut at that height that would be great as well. Any help would be greatly appreciated.
