Troubleshooting Tips for Cub Cadet 3X Series Three-Stage Snowblowers

Cub Cadet ResidentialCub Cadet 3X snowblowers are easily the most powerful models on the market, and they’re made by a manufacturer whose name is essentially synonymous with durability. Even so, the occasional starter problem or engine issue can cause homeowners a bit of frustration when they operate the equipment throughout the winter. Most of these issues are pretty basic, and they can be quickly solved with a number of quick fixes that range from fuel valve adjustment to the removal of obstructions. Before calling a Cub Cadet retailer to arrange for equipment service, try these key troubleshooting tips first.

Engine Problems: What to Do if the Engine Won’t Start

The Cub Cadet 3X has one of the most powerful engines on the market, but that doesn’t mean it can start if the fuel valve is in the wrong position or if there simply isn’t enough gasoline available to get the equipment operating. Before assuming the worst, go ahead and try each of these quick fixes that will likely get the engine started in no time at all:

  • Check the choke, which make positioned incorrectly. It should be set to the “choke” position, or the engine will not start from a cold temperature.
  • Check the spark plug, which may be disconnected and causing the engine to suffer from a lack of power. A damaged spark plug will have much the same effect, and may require full replacement of the part with an OEM option.
  • Make sure that the fuel tank is full, and be sure that all fuel used in the snowblower is “fresh.” Old fuel from last season, or even last month, is much harder to ignite than newer fuel purchased in the last several days.
  • Make sure the ignition key is in the ignition itself, otherwise the engine won’t start by design.
  • Connect the extension cord to the equipment and make sure the connection is tight and secure on both ends.

An Erratic or Surging Engine is Usually Pretty Easy to Fix

If the snowblower’s engine starts without much effort, but quickly sounds as if its surging and then losing power, there are typical several pretty quick things to check. Everything from fuel quality to fuel clarity could be causing the engine to suffer from a lack of consistent power.

  • Make sure there is enough fuel in the fuel tank, and be sure that the fuel being used was recently purchased. Stale fuel will cause numerous engine complications.
  • Check for dirt or other debris in the fuel. If the fuel is not clean and clear, empty it responsibly and dispose of it. Refill the fuel tank with clean, fresh fuel and try again.
  • Make sure the choke lever has been switched from its original “choke” position to the “run” position. The snowblower cannot run properly if the choke lever is not properly adjusted after starting the engine.
  • If these solutions don’t work, consider the possibility of contacting an authorized service technician who may be able to help with other causes like an over-governed engine or a carburetor that requires extensive adjustment in order for the engine to resume normal operation.

An Engine that Loses Power Typically Has Fuel or Spark Plug Issues

Once the engine is on, most Cub Cadet 3X snowblowers should be able to maintain a high level of power for very efficient snow clearing. If this is not the case, it’s time to check the fuel, spark plug, and other areas of the equipment that supply an actual energy source to the engine.

  • Make sure that the spark plug wire is not loose. If it is, stop the engine and tighten the spark plug wire. Start the engine again and verify that the problem has subsided.
  • Check the current fuel level. A low level of fuel will cause the engine to suffer from low power issues before it eventually turns off permanently. If fuel is required, add it before resuming operation.
  • Make sure the gas cap vent hole isn’t blocked by snow, ice, or debris from around the lawn. Blockage of this hole can cause the engine to lose essential ventilation and eventually turn off. Clear away any snow or debris and turn the equipment back on. It should now be running perfectly.

Discharge Issues: Check for Obstructions or Belt Issues

If the snowblower runs perfectly but is having problems discharging cleared snow, the problem is almost always the fault of a major blockage. With a snow clearing bar, check the intake and discharge chutes for ice buildup, snow blockage, or large debris that could be causing problems. If these things are not to blame, check that the auger belt has not been damaged or removed from its pulleys.
