  If your Kubota Engine is difficult to start, several factors could be responsible. The fuel may be thick, hindering its flow; in this case, check the fuel tank for water, dirt, and impurities, and replace the fuel filter cartridge if needed. Alternatively, the engine oil might be too thick due to cold weather, causing slow cranking; use oils of different viscosities depending on ambient temperatures (e.g., 10W-30 in winter). Finally, the battery could be discharged, preventing the engine from cranking; charge the battery to resolve this.

  Insufficient output from your Kubota Engine can stem from several causes. Make sure you have enough fuel by refueling and checking the fuel system. A dirty air cleaner can also restrict output, so clean the element. The output may be limited due to a trouble, so check the engine warning lamp. (If a trouble occurs, it means that the ECU might be in the output limiting mode.)

  If your Kubota Engine suddenly stops, it could be due to a few reasons. First, check if you're out of fuel and refuel if necessary, also check the fuel system. The air cleaner might be dirty, so clean the element. In some cases, a serious issue might have caused the ECU to force the engine to stop, so check the engine warning lamp.
