In May I bought a new D170. It replaces my 11 year old 42" Sears Craftsman. When ever mowing bahiagrass it always left a strip down the middle. New blades going slow it didn't matter. Only way was to cut very short. I was afraid the new JD D170 would leave two strips. With the 54" it cuts even tall bahia cleanly. Those of you who don't have bahiagrass it can be tough grass to cut. I don't know if there is a slight overlap between blades all I know is it works. What a relief. Anybody else have bahiagrass stories?

I call that strip a mow hawk. My old 2005 JD L108 42" deck would do that but only when cutting very long grass. Usually 10" or longer. Didn't matter how slow I went. It only had a single cylinder engine so lack of power was properly part of the problem.

2 blade decks are usually set up one of two ways to avoid this.
They have a timing belt that drives the spindles. This way neither blade is in the same place at the same time.
They have an off set. One blade spindle is mounted slightly ahead of the other. So cutting in a straight line covers the complete distance underneath the deck.
3 blade decks are almost all overlapping. This is why the center blade is mounted forward of the others.

Good luck with your new tractor.

I have a D170 54" - it cuts great! I've mowed overgrown 10 plus inch stuff down no issue. I think Deere puts good effort into their deck designs - it makes all the difference in the cut and how material moves through and out of the deck. :thumbup1gif:

I have the same issue with bahia grass with a 60 inch deck. I've put new blades on and sharpened them after they get dull and it still misses strips every time I mow. I've just resigned myself to the fact that I have to go over it again.

My lawn is 75% bahiagrass. I run a mulching kit full-time on my Z445 and it has no problem cutting it. I usually try to catch it before it makes the "Y" (see pic below). I find that's when it's the toughest to mow.

That grass looks like it was sent by the devil himself. lol

Try out a set of Gator blades for your mower deck. The metal is a little thicker then the stock blades. Plus they have a unique top side that really mulches up the grass. Used a set last season for the first time. At the beginning of this season I put the stock blades back on. Seeing they were already sharpened professionally. Then I sent the Gators out for the same. Just cleaned my deck and put the Gators back on last week. Wow what a difference! The stock work but no ware near as good.

I've been using the gator blades and I still have the problem. I mow every 5 to 6 days and have to sharpen my blades every other mow and have to replace them when Summer is over. They get worn down to about half their width in just one season. Too sandy around here!

Wow that grass is really tough stuff.
Is that the only type of grass that will grow in your climate?

It's what was growing on the 4 acres that I mow when we bought the property. There are several types of grass down here but I would have to put in a sprinkler system to keep it healthy. Maybe someday when I finish all of my other projects. I wish I could grow the kind of grass I had up in Wescosville.

The JD mulching blades do a good job cutting it.

That's when it's the toughest to mow, not that it doesn't cut it. If I let it get to that point ("Y"), and it is damp, I have to mow at a slower speed than WAO*. :good2:
