Reinstalling blades after sharpening 60MMM

[Captaincj]

Question, just sharpened the blades for the first time on new BX2380, and after reinstalling the blades on 60MMM is there an optimal/preferred/best VooDoo way to align the blades directionally relative to each other? In other words, all blades at 12/6 o'clock? Outers at 12/6 o'clock, inner at 3/9 o'clock? All different? Doesn't matter?

Thanks to all.

There is no need to worry. They can not hit each other.

It does not matter.

There is a caution in the Kubota installation manual I have .

The blades should be positioned as far from each other in order to prolong the life of the blades.

See attached from the manual.

My sense is that the concern is for a blade blasting stuff against the turned up back side of the blade in its discharge path

I alternate my blades by 90 degrees after sharpening, but they will end up random in short order. If you cut a LOT of grass, the blade on the discharge side should be relocated to the inside spindle to even out wear. I cut about 25 acres per week and can tell the difference in blade wear, but not much.

Seeing that diagram really surprises me. Unless the blades are chain driven, they would never stay that way.

Bingo.

I rotate my blades one position each season upon sharpening.

I was more thinking cut quality or harmonics or whatever.

You know, looking for the best dude machine VooDoo...

SDT, you can make an entire season without resharpening?

Probably depends on where he lives, here in Minnesota we only cut grass two months per year...

Yes.

I sharpen each fall upon removal and servicing of the MMM. I usually sharpen with a file but doing so goes through a good 14" File to sharpen all three blades.

I rarely hit anything other than grass when mowing.

Actually, that picture is showing to rotate the blades after sharpening.
The left blade is moved to the center, the center blade is moved to the right, the right blade is moved to the left.

The clocking of the blades makes no difference as the will slip in the belt or on the spindle a little over time anyway.
Just make sure they are not downside up! We see that several times a season.

Well dang! I can see that now, but having seen that diagram in the past, I interpreted it also as clocking the blade rotation position.
