Grass left uncut

    I just picked up an 06' Bunton 52'' ZT.

    I noticed that it was leaving strands of grass sticking up after cutting. I attributed this to dull blades. Well I replaced the blades with brand new high lift blades, and it continue to leave grass behind uncut.

    What is the issue? I was thinking maybe it was just under powered at 19hp, but it leaves strands behind no matter how thick or thin the grass might be.

    Any help would be appreciated, having to double cut yards is really eating up time. Thanks.

    I always double cut, it's not an option.

    I'll have to check the deck belt. I have a 48" bobcat WB that doesn't leave any stragglers on the same lawns.

    Interesting. This happened to me last week and my blades needed to be sharpened. My deck belt isn't very tight until the blades are engaged... I hope I don't have the same issue as you this weekend.

    You didn't say if you were side-discharging or mulching or bagging...or a combo of all three.
    Try reducing your forward speed...worth a try.
    3-bladed mowers frequently require double-cutting in the Spring due to the sheer volume of lush/juicy grass that is processed.

    Side discharge. Its an issue across all volume of grass, low to high. I know it is machine related because my WB cuts these same properties without issue.

    The issues could either be damaged baffles, blade tip speed ( belt not tight enough when engaged) or blades are the wrong length. Most likely the baffles if they hit something.

    Make sure that the underside of the deck is clean and that one of the blades isnt accidentially on upside down. My other thought is definitely belt tension...

    Have you checked your deck rake?
