    Why is my Kubota RCK72P-F39 Lawn Mower streaking uncut grass?
    • C
      Catherine LeblancJul 30, 2025
      Streaking of uncut grass on your Kubota Lawn Mower can happen for several reasons. It could be that your ground speed is too fast, so try slowing down. The engine rpm might be too low; in that case, mow at full throttle and check the engine rpm. If the grass is too long, cut it twice. Dull or damaged blades can also cause this, so replace or sharpen them. Finally, check for and remove any debris in the mower deck.

      If the discharge cover of your Kubota Lawn Mower is plugged, it could be due to several factors. If the grass is too wet, wait for it to dry. If the grass is too long, raise the cutting height and cut the grass twice. It might also be that the cutting height is too low, so raise it. Ensure you are mowing at full throttle, and if your ground speed is too fast, slow down.

    Why is my Kubota Lawn Mower blades scalping grass?

      Victoria MurrayAug 12, 2025
      If your Kubota Lawn Mower blades are scalping the grass, it might be because the cutting height is too low, so raise it. Reducing speed on turns can also help. If there are ridges in the terrain, try changing your mowing pattern. For rough or uneven terrain, adjust the gauge wheels and antiscalp rollers. Also, ensure the gauge wheels are adjusted correctly. Bent blades can also cause scalping, so replace them if necessary.
