Safety Switch Problem
Honestly, this is the most uncomplicated problem people often face. Those who have lawn tractors surely have experienced this issue.
Well, what happened in this case? Most often, the safety switch, which is situated under the driver seat, got unplugged or disconnected. Therefore, the safety switch is a big reason for cub cadet zero turn mower turns over but won’t start problem. Anyway, don’t worry, the solution is easy.
To fix this issue, you just must turn the switch on, and recheck the site mount plague. It’d be great if you unplugged and plugged it back quickly before starting the tractor.
Defected Spark Plug
The spark plug problem is a genuine tractor problem that often happens when the tractor gets old. This problem is even hard to find.
Sometimes the spark plug gets defective for various reasons, and the cub cadet zero turn cranks but won’t start.
Well, what spark plug does? It actually produces a spark for the fuel so that the engine gets power.
After troubleshooting the spark plug, you’ll experience a misfiring motor and a hard starting engine problem. The solution would be to change the spark plug or fix it. This problem can happen again and again unless you use a good product.
Fuel Solenoid Issue
Another problem creator is fuel solenoid. This thing is situated just beside the fuel tank.
Fuel solenoids help to get the fuel inside the tanks. If the fuel solenoid has any specific damage or disfigurement, it doesn’t let the fuel inside.
What would be the solution for that? Well, first of all, make sure whether it’s clogged by something or not! If it’s clogged, then clean it. Otherwise, if the problem is disfigurement, replace it.
Check the Valve
There’re enormous valves in the main function of the tractor. If those valves aren’t tightly connected to the targeted parts, it’ll start creating trouble. Basically, the pressure, ball, and hydraulic valve are the main connectors of the function, so check them out first.
What’s the solution, then? Here you just have to check all the valves serially to see whether they’re properly connected or not. If some of them are loosened or damaged, you need to change or refix that.
Even when your tractor is good but old, you should replace all the old valves. After ages, when your cub cadet zero turn turns over, but won’t start, the reason would be nothing but the old valves.
Ignition Coil Issue
There’re two types of starting problems. The first problem is when the car doesn’t properly start, but engines make sounds for a moment. And the other reason is when engines don’t even respond or make a sound.
When you face the second problem, you can be sure that this is an ignition coil damage issue. The ignition coil mainly supplies voltage to the spark plug. And then, the spark plug passed the spark to the engine directly.
The key solution is to clean the ignition coil because rust and dust jammed in the entrance. Clean that properly and reinstall again; otherwise, replace it if things seem very bad.
Flywheel Key Problem
When the flywheel gets damaged, it becomes a huge problem for the tractor. Though it’s a less critical point compared to others, it can still be a big reason for cub cadet tractor turns, but does not start a situation. This flywheel basically creates the rotational energy to do various tasks. In addition, it also works as a defender of the lawn engine.
If the flywheel key is broken or dysfunctional, the engine will start creating problems. As a result, the cub tractor will crank but won’t start anyway.
Replacing is the only solution because the key is small and near impossible to refix.
