  Tiffany RobertsAug 21, 2025
  If you notice black or dark gray exhaust gas from your Kubota Lawn Mower, it could be due to a few reasons. You might be overloading the mower, so try decreasing the load. It could also be due to using low-grade fuel, so switch to the specified fuel. A clogged fuel filter or air cleaner could also be the culprit, so replace the fuel filter and clean or replace the air cleaner. Finally, deficient nozzle injection can cause this issue, so repair or replace the nozzle.

What causes low oil pressure in my Kubota WSM BX2680?
- L
  Lisa HardinAug 30, 2025
  If you have low oil pressure in your Kubota Lawn Mower, it could be due to several reasons. The engine oil might be insufficient, so fill it up. The oil strainer could be clogged, so clean it. The relief valve might be stuck with dirt, so clean it. The relief valve spring might be weak or broken, so replace it. There could be excessive oil clearance of the crankshaft bearing, crankpin bearing, or rocker arm, so replace them. The oil passage might be clogged, so clean it. You might be using a different type of oil, so use the specified type of oil. The oil pump might be damaged, so replace it. Finally, the oil filter might be clogged, so replace it.

Why is the engine revolution not smooth on my Kubota WSM BX2680?
- M
  Mark SmithSep 1, 2025
  If your Kubota Lawn Mower's engine revolution isn't smooth, several factors could be at play. Start by checking the fuel filter for clogs or dirt and replace if necessary. The air cleaner might also be clogged, so clean or replace it. Ensure the injection pipe retaining nut is tightened to prevent fuel leaks. Issues with the injection pump, such as malfunctioning, may require repair or replacement. Other potential causes include incorrect nozzle opening pressure (adjust it), a stuck or clogged injection nozzle (repair or replace), or a malfunctioning governor (repair).

Why is my Kubota WSM BX2680 Lawn Mower engine overheating?
- T
  Teresa GaySep 3, 2025
  If your Kubota Lawn Mower is overheating, there are several possible causes. Check if the engine oil or coolant levels are insufficient and fill if needed. Inspect the fan belt for breakage or elongation, and replace or adjust it accordingly. Clean any dust clogging the radiator net and fins. If the inside of the radiator or coolant flow route is corroded, clean or replace them. A damaged radiator cap should be replaced. Avoid overload operating by reducing the load. Finally, a damaged head gasket should be replaced.

Why does my Kubota WSM BX2680 have deficient output?
- E
  Eric Anderson IVSep 6, 2025
  If your Kubota Lawn Mower is experiencing deficient output, it could be due to several reasons. Incorrect injection timing may be the cause, so you should adjust it. The engine's moving parts might be seizing, requiring repair or replacement. A malfunctioning injection pump or deficient nozzle injection can also lead to this issue, so repair or replace the pump or nozzle as needed. Additionally, a dirty or clogged air cleaner can reduce output, so clean or replace it. Finally, a compression leak may be the problem, requiring you to replace the head gasket and tighten the cylinder head screws, glow plug, and nozzle holder.

- S
  Shane ThomasSep 8, 2025
  If your Kubota Lawn Mower's battery is quickly discharging, it could be due to insufficient battery electrolyte (fill with distilled water and charge), a slipping fan belt (adjust belt tension or replace), disconnected wiring (connect it), a damaged rectifier (replace it), a damaged alternator (replace it), or a damaged battery (replace it).
