Hey guys and girls I found out something new today, I found out about blade timing. It seems that you need to position
your blades as to uptimize air flow and lift. They said that while changing blades it matters how they are positioned when put back on. If you have a three blade set-up, one blade goes vertical, one horizontal, then one vertical. This was new to me, has anyone heard of this or could tell us a little more about this.

Good Luck!

Pure bullschitt, i have never done that and my mowers work fine.

what happens when you turn off the pto?, they slow down at their own rate and would mess up the pattern.

I have a Kubota with a belly mower w/ t3 bladea and in the manual it says that you are supposed to position them a certain way. Itried if diffferently one time and It cut terrible. They dont go as you said though. The angles are a little different.

Never heard of this but always wondered. I have always postioned my blades in the same direction. I will try to stagger them this week and see if it makes a difference. Do you know the reasoning behind this? Also if running double blades should you stagger the blade setup? thanks for the thread. Just another reason LS in an invaluable resource.

Great concept! However, just not practical. Like it was said, not just when you disengage the blades, but as soon as you engage them, some will grip just a little sooner than others, throwing the whole pattern off. Try it and see!

I've never given it any thought until now. I just mount the blades in any random position. Interesting question, though. Maybe I've been wrong all this time. Lets see what responses this brings.

blade timing

I've been thinking about this after reading some of your thoughts,now on my mowers all of the blades are held in sync
as one complete unit by spring loaded idler pullies. all three blades are kept under belt tension all the time. So when you kick in your electric cluch all three should turn at once,and when you turn off your PTO all three should slow
down at the same rate, the only thing that would change the pattern is belt slippige.
