Cub Cadet RZT 50 Problems

1. Cub cadet not starting 

Problems with your cub cadet not starting are usually due to a bad engine. That doesn’t mean the engine is the only reason your cub cadet is not shrinking; some reasons your cub cadet mower refuses to start is due to a complicated safety interlock system, bad starting position, low fuel, and even dead batteries. 

Your safety interlock system requires you to push the control levers fully into the neutral position, and the PTO which controls the blade should be disengaged or even set to “off”. If not, the mower would not tart. Ensure that you heed all these if you want your mower to move.

Reasons Why Your Cub Cadet RZT 50 Won’t Start Solutions

Low fuel or stale fuel Ensuring that you top up your fuel or even completely change the power in the fuel tank. 
Battery issues Replace dead batteries 
Safety interlock system Ensure that the PTO is disengaged. 

2. Failure Of Engine to Start 

There are several reasons why the engine of your cub cadet RZT 50 mowers would refuse to start. Some of the reasons include not activating your choke, working on an empty fuel tank or blocked fuel line, bad spark plugs and not setting the throttle lever in the correct starting position. 

You can quickly fix these problems by following a few steps, like ensuring that you always activate your choke before starting the machine. Whenever you realize your fuel tank is low, ensure that you top it up or, even better still, replace the entire fuel in the tank if the existing fuel is stale. 

Replace your old spark plugs because these spark plugs wear out over time, and in cases where the throttle is in the wrong position, ensure that you always set your throttle in the correct place. 

Cub Cadet RZT 50 Engine Problems Solution 
Parking brakes not engaged Ensure that your parking brake is in an “engaged “ position before starting.
Blocked fuel line Always clean your fuel tank before the operation, and also ensure that you replace the fuel filters to reduce clogs. 
Inactivated choke Activate your choke before starting the machine
Flooded engine Ensure you crank your engine while the throttle control is set to the “FAST” position. 
Engaged PTO knob Ensure it is set to “ disengaged” before starting at the machine. 

3. Excessive Vibration 

Excessive vibration is a common problem for most mowers, not just the cub cadet. This problem is when your mower starts vibrating abnormally as soon as you start up your machine, which is usually due to a loose or unbalanced cutting blade and a bent cutting blade. 

The easiest way to fix these blade issues is by tightening all the blades and spindles of your mower and replacing the edges if necessary. 

4. Uneven Cut 

Your mower is said to have cut grass unevenly when the grasses are not cut in a leveled manner. Some reasons your mower blades are cut this way are dull blades, uneven decks and tire pressure. 

You can quickly fix these problems by performing deck-to-deck adjustments and also do well to check your blades and replace them if necessary. If the problem is a blunt blade, ensure that you sharpen the blades before operation. You should also check the tire pressure in all four tires and ensure you pump the tire up to the amount you are supposed to. 

5. Mower Refusing to Mulch Grass 

Your mower not mulching grass properly is only an issue if you install a mulching kit in your mower. Some reasons why this happens are if your engine is moving way too slow, working with wet grass, working with a dull blade and if the grasses in your lawns are too high. 

You can quickly fix this issue by placing your throttle in a closed position; that way; your mower would be able o mulch grasses much faster, waiting for your grass to dry up before mulching, sharpening and replacing your blade when necessary and also, mowing twice.

By that, we mean trimming once to a bit higher height and then mowing again to the size you desire.
