I have a Hustler 3400 with the 72" quadcycler deck. I have been running the stock blades for a while....and they just don't do a very good job. They leave corn rows of grass that is not cut as low as the rest....so I have to mow twice to get everything at the same level. I purchased a new set of blades from my local dealer....and they a little better but not much....I am desperately looking for another blade solution. I have search all over and cannot find anything with a 1/2 bolt hole to fit this quadcycler deck. I look forward to your suggestions.
