    I am not too convinced that's an issue since all my lawns get bagged every week all year lawn so there should be almost no thatch buildup..

    Thatch does NOT come from mulching or side discharging unless a thatch problem already exists in the lawn, and even then it is nowhere near the main cause of thatch buildup.

    Here's some good reading for anyone interested in it-

    Aggressive fertilization. Thatch can accumulate quickly following aggressive nitrogen fertilizer programs. Nitrogen promotes thatch development because it increases production of root and stem tissues. The ability of some nitrogen sources to acidify soils also may reduce the rate of thatch breakdown.


    good ground+lots of water+plus optium growth tempeture=the issues above(increased production of root and stem tissues. if he bags then this should not be his issues anyways

    question, did you guys have lots of dead grass from last year? we did. Your grass should be green, not brown.

    Yes we did have a very dry summer last year but our grass this year is green for the most part not brown..

    right, but in the second pic I see brown grass mixed with the green. cutting does not turn the grass colors

    What you are seeing is just that particular property it has no irrigation and yes dry spots but that has nothing to do with my cutting issue.

    ok lets talk basics here. Brown comes from either dead or dominant/unhealthy grass/ or thatch. If its a perfect lawn you should not have brown roots. Well you don't have thatch so its comes down to cut/brown roots. Are you level? same tire pressure on both sides? nothing is sagging? When you take a rake and pull the grass back is it all level? Are you just bending the grass down because of a low roller and making it look like an issue?

    Trust me when I say this..all basics HAVE been covered. Everything you just mentioned has been checked multiple times. I can adjust that side of the deck almost a half inch higher than the other side and still have the brown strip.

    Yea, I realize that. I was just pointing it out since he made mention that he bags to avoid creating thatch, which side discharging won't do in and of itself.
