How to troubleshoot starting problems with my Kubota Utility Vehicle?
If your Kubota Utility Vehicle engine is difficult to start or won't start, several factors could be the cause. First, ensure the range shift lever is in the "NEUTRAL" position and the key switch is in the "ON" position. Check if you have fuel and that it is of good quality. Also, inspect the fuel system for water, dirt, clogs, or damage. Other potential issues include a clogged air cleaner, a defective spark plug, a blown fuse, incorrect engine oil viscosity, or a weak battery. Clean battery cables and terminals. Charge the battery. In cold weather, remove the battery from the engine, charge, and store it indoors, installing it only when the machine is in use.

For high tension cord and ignition coil issues, consult your KUBOTA Dealer. For fuel issues, clean or replace fuel lines and replace the fuel. If the air cleaner is clogged, clean or replace the air cleaner element.

Why are the exhaust fumes from my Kubota RTV400 colored white or blue?
