I will try and explain this the best i can. When you are putting your blades back on you mower, ( I have a zero turn 60") Is there any pattern that is better than another. Usually i just tighten them up whereever they end up. Then i started thinking that over time they will get out of alinment because of the belts slightly slipping on the pulley here and there. Ive never had a problem with just bolting them on, my cut and everything is great, but just wanted to see if anyone else experimented with this and saw any differneces? / \ -- / / / couple of example of 3 blades bolted on under deck. hope you understand what im talkin about.
