The specifications for a Kubota RTV900 tended to focus mainly on engine size and its power output. These specifications will vary slightly depending upon the age and model of the RTV that is bought.

The current Kubota RTV X series have traditional Kubota diesel engines. These are three cylinder liquid cooled engines starting with a 21.6 HP engine, up to a 24.8 HP engine. It has a variable hydraulic transmission which has a wide torque band, and large oil coolers. This

Kubota has traditionally had what it refers to as a strong high rigidity frame of the vehicle, which is acknowledged that the industry has been one of the best available. It ensures the safety of the operators in the vehicle, and provides a framework that allows for considerable loads to be carried in it.

Below are listed some of the most common problems with the Kubota RTV900, and some general ideas as to how these problems can normally be dealt with.

RTV900 Won’t start

Check the following

  • Check the transmission gear shift lever. It may not be in the right position. Place the range shift lever into neutral and check the engine throttle lever is not put forward. Move the throttle half or full impulse.
  • Check and see if the battery connection is loose or corroded. Check connections and retighten it necessary
  • Check and see if the fuel shutoff valve is closed.
  • Check and see if the fuel is either stale, or at an improper fuel level. Drain the tank if necessary of all fuel and refill.
  • Check if the engine oil viscosity is correct or not, and if not completely change the oil in the tractor.there
  • Check and see if the fuel filter is plugged, and if necessary place.
  • check if the air intake filter is plugged, and if it is clean or if necessary replace the air filter elements.
  • Checked to see if any of the fuses have blown and if necessary replace one or all of them.

RTV900 Won’t start, just clicks

Check the following

  • Could be potential battery issues. Check that all the motor and battery connections are clean and tight.
  • Check the battery voltage and its holding power and replace it necessary.

RTV900 Turns, but will not start


  • The fuel may not be getting to the cylinder. check the fuel level, the shutoff valve and the fuel filter.
  • Check the air filter. It may be too cold for the cylinder to combust mixture of air and fuel.
  • Move the throttle back to idle and then half throttle and attempt to restart

Starting diesel engines in cold weather


  • Use proper seasonal diesel blends. Winter blends have certain additives to ensure that they remain liquid when it is cold.
  • Watch and check for bio diesel percentages
  • idle the engines for a time before using, this increases its efficiency and range.
  • Maintain the cooling system properly. Check the overall level and quality of coolant.
  • Use various engine starting aids if necessary. Some of the most common are glow plugs, intake preheaters and block heaters.
  • if the engine fails to start, this could be due to the cold start system malfunctioning, the fuel injectors may be dirty or there may be a faulty switch.

RTV900 Engine Problems.

Either the engine went start, or it is hard to start or start and then stalls. Check the following :

  • There may be no fuel flow. check the tank, hoses, feel shutoff valve and fuel filter. Make sure they are all functioning properly and that there are no leaks from any of them.
  • The exhaust smoke may be black. This may be due to too much oil, a clogged air filter or dirty fuel.
  • The exhaust smoke may be blue or white. This may be due to fuel inside the muffler, a clogged fuel injection nozzle, poor quality fuel, a defective thermostat or that may be sediment in the fuel which may also be stale.
