What to do if my Kubota Z781KWi Lawn Mower engine is difficult to start?
- D
  Debra FranklinAug 8, 2025
  If your Kubota Lawn Mower engine is hard to start, make sure you're sitting on the operator's seat and that the parking brake is engaged. Also, ensure the PTO switch is in the “DISENGAGED” (OFF) position, the motion control levers are in the “NEUTRAL LOCK” position, and the key switch is in the “ON” position. Check your fuel level and quality; if the fuel is stale or there's water/dirt, replace it and the fuel filter. A clogged air cleaner, damaged spark plug, or blown fuse can also prevent starting. Viscosity of the engine oil and weak battery can be the cause of the problem. Clean battery cables and terminals. In cold weather, remove the battery from the engine, charge and store it indoors, and install it on the machine only when the machine is going to be used.

Why Kubota Z781KWi has insufficient engine power?
- R
  Renee NobleAug 21, 2025
  If your Kubota Lawn Mower engine isn't providing enough power, the issue could stem from insufficient or dirty fuel, a clogged fuel filter, a clogged air cleaner, or a damaged spark plug. You should check the fuel system, replace the fuel filter, clean or replace the air cleaner, and adjust or replace the spark plug as needed.
