You only need to raise the deck if you have a lot of extra clippings piled up. Under normal conditions, you can leave the deck at the same height and roll on.

If and when I have to double cut I leave the deck at the same height.

I feel sharp blades and bagging saves me time and fuel. I have dumps spots on many of my properties and when I have to take clippings away, I have a free spot that is 2 driveways down from my place. But, we can save the mulching/throwing/bagging debate for another time.

I have a different theory on this. If I am double cutting for stragglers or such I leave the deck the same height. If I am double cutting to spread clippings I raise the deck .5 to 1", depends on how much needs spread out.

Same as Turf Dawg, I raise the deck half an inch to spread the clumps and piles of clippings. Just enough to clean up the bulk laying on top, not suck up every blade you cut. Depends on the deck I imagine, but on my old lazer it cleaned up nicely, while letting me go like the dickens, and easier on the machine with the deck up a bit more.

Two approaches.

1. Mow slower the first pass and make sure you get a clean cut so the grass is nice and level. Second pass mow 1/4" higher at high speed to clean up any clumps.

2. Mow medium speed first pass, accepting that you may have some spots where thick grass causes stragglers, etc. Second pass mow at same height, again at medium speed, ideally with perpendicular passes, and both disperse clumps and smooth out any missed areas from the first pass.

I raise the deck almost every time on the second pass. I'm almost always just trying to get rid of extra clippings.

Yes 1/2" higher on the second pass really makes clippings disappear.

i don't see how this would have any effect on the cut.?

i work at 3.50, i would just leave it, raising might not get what was left behind


but what do i know, i've never tried it?

I raise mine a 1/4" too. The reason why on my mower it disperses the lawn clippings better especially when wet. You can never tell the difference in the two cuts.

Is this for mulching or side discharging or both?

i'm gonna test it on an account of mine tomorrow that ALWAYS gains too much height in 7 days between cuts.


who knows!?

I do it the opposite... with high grass, I raise the deck 3/4" higher for first cut, then lower it for the second cut. Cuts up the clippings better, leaves a beautiful cut.

Someone here on Lawnsite posted about doing it this way ages ago.

I mulch and this is what I do on any lawn that is obvious will require more than one pass. For mulching this eliminates clumps that stick together and may not get picked up on the second pass. The best cut ALWAYS comes when not processing to many clippings on one pass and this method does this best.

The problem with that approach is you have to mow every bit of the lawn again on the second pass. Can't just streak through hitting just th eclippings

i leave it at the same height and change direction unless there is a lot of clippings to be scattered

I somewhat agree, but I hope you never have to mow the likes of Dallisgrass, Goosegrass, Tall Fescue, Turfted Lovegrass, and Yellow Foxtail.
My Walkers do less back cutting compared to our Exmark's. This only applies to dry grasses.........!?! And if you are mowing at an inch in height too!!!!
