Yeah, I'm having the same issues with my sod that was put down at the end of march. The bermuda is doing fairly well, nice and green, but there are places in the back that has some type of thick blade grass/weed coming up in spots. Those spots have alot of that grass/weed. I'm hoping that the bermuda will take over. I'm going to lay off the watering to about 1 time a week and see how it reacts. I'll spot water alittle inbetween where some of sod wasn't taking, hopefully it'll help the bermuda spread into the semi-dead pieces. I've mowed it about 3 or 4 times already. I have a toro 20055 mower and the lowest it'll go is 1 1/4" which is about the lowest I can probably go on my terrian. Not that sod is uneven, just that I got banks and hills, and I don't think a reel mower will do well. Will keeping it at around 1 1/4" be enough to choke out the weeds?

Who laid your sod? All those seams from the sod should not be lined up and should have been laid in a brick pattern. It's not a huge mistake, but the reason you lay it in a brick pattern is to keep the sod pieces from shifting. I would not apply any weed n feed products or pre emergents until your sod has rooted together and you can no longer see the seams in the lawn. Once you start seeing the lawn green up start watering it to keep the soil underneath moist and then you can apply a starter fertilizer or a balanced fertilizer like 10-10-10. You are better off spot spraying the weeds over using a weed n feed product. The weed n feed product don't usually work all that well and cost a lot more. Just be sure not to spray weeds when the temps are over 85F as it may harm your lawn. Once all the seams are gone you can start using the Scott's Turf Builder for the rest of the season. You want to apply 1 lb of Nitrogen every 4-6 weeks, this will help keep the grass healthy and choke out a lot of the weeds.

YOU NEVER NEED TO TILL. Oh, sorry was I shouting? You never need to till in preparation for grass. I'm short of time here at lunch so I'll just drop that and leave it without explanation. Don't let the bobcat guy on your lawn. If he can come up with a real tractor, then fine, but bobcats take 10 times longer to do the grading job as a tractor with a box blade. A tractor can do that job in 15 minutes to an hour. A bobcat might take a week. It would be best if you could rake the dead stuff up. You want good contact between the bottom of the sod and the top of the soil. Roots will not grow through the air looking for soil. Gotta run, but I have more to say. If you want to ask more questions, go for it.

here are few more photos these are in my backyard. seem like the same plant. 1st one is 7 inches tall and the other 2 photos seems like the same plant but fully matured.
