   We are using the John Deere 2500E. We are cutting at .145". We are using standard bedknives with 11 blade reels. Each reel looks like they are cutting well. We are using solid rollers. All the bearings seem to be fine. Each cut looks the same. What I am seeing is a line in between each reel, like the overlap of each reel or something. Yesterday morning it looked fine but I noticed in the afternoon. Some days it is very visible in the morning. Per John Deere the bedknives are ground at 7 degrees.

   Check the center basket lift frame, rubbing. There is an adjustment to raise the lift frame.
   Had to do this adjustment on two machines, hoc. 120.

   we have the new style baskets. There is no frame. The basket clips on from the top.

   I am thinking about measuring the reels. Maybe they are bigger on the edges(or smaller)? Also was going to measure the distance between the bedknife and reel with feeler gauges.
   
   What do you guys think?

   Jeremy,
   
   Did you look at the greens with a Prism to see if indeed there was a different HOC on these lines? I ran into this same thing before with 2500E and when viewed through the prism the HOC was the same. When I asked our JD dealer about it he came out and looked at them also with the prism , best answer we could figure out was that its the overlap lines from the center cutting unit. Sometimes we saw them sometimes not, depended on the angle the sun was hitting the greens. I know its frustrating to see them but I have come to the mind set that as long as the HOC is dead on track then there is no playability issue. It looks bad but there was nothing we could do about it.
   
   As far as measuring the distance between the bed knife and reel if you do it with a feeler gauge you should have .002" clearance between the bed knife and reel, this is the proper set up for JD Reels. The only other adjustment that you could possible make would be make all the front roller paralleling the same on the mower. I have done this once before with the gauge its very hard to get but possible. Best would be using a bench plate to parallel your units.

   I run extended knives, and run in bracket setting 2. We always set the eccentrics on the front rollers to the shallow points lining them up at 3 & 9 position, then will fine tune off the right side as you face the cuuting unit. This keeps them as close as you can to all having the same bedknife attitude. Usally when I see the lines I will flatten out the attitude in the summer to get a better looking after-cut appearance. When we head into the fall and winter we go with a little more aggressive setting as the turf is firmer, turfs not puffy from the high humidity, and not we're not cutting as much. Hope this helps.
   
   Regards,

   Been dealing with those lines for a few years now, here is what my "research" has shown me... It is an overlap mark - of sorts - varied by a number of conditions, IE: moisture content of the turf, temp changes - both in the soil, the grass itself, and the atmosphere - bedknife/reel attitude, the fact that on these cutting units the OEM rollers weigh about 18lbs apiece, mowing speed, to name just a few. Some we can have control, or affect, on and some we don't. One factor I have had success with is changing the front roller out for one of less weight. R&R has an aluminum grooved roller that fits and is about 10-11lbs lighter than the OEM ones. I tried rollers from Jacs GKIV which are hollow tubes and too light to keep the JD units tracking properly but the reduction of weight acieved with the change to the R&R rollers seems to minimize the marking. The markings never really permanently go away but I've been able alleviate them on most days and minimize them on the days that turf, or atmospheric, conditions make them highly visable. Thats my experience anyway, hope we all are helping...
