Hi Sven Tryliqvist,
Either your your rear roller requires adjustment, or your front roller has a bent frame and is slightly out of whack, but in saying that I'm sure you are going to say to us that all you've done is remove the reel and bed knife to send it off for grinding and then re-installed them when you got both items back ?
Just wondering which side it is that's digging in. It depends then which direction you are mowing I guess it it certainly looks as though you are only mowing one way.
There also could be an issue of how the bed knife is sitting and that very much depends on how it's been installed. I always install them by initially hanging them on the two top bolts and then lightly tighten those two up but not too tight. Then I'll swing the bed knife upwards so that the two lower bolts can be slipped through their holes and then tighten those two up lightly.
From there I'll tension up the top two and then the bottom two. This way you can ensure that the bed knife is evenly positioned. From there you must set your rear roller from that datum point and then the front roller to suit the parallels of the bed knife and rear roller.
Hope that this helps you out.
Cheers,
BB.
