Cub cadet hydrostatic transmission won t move

Cub cadet hydrostatic transmission won t move. The engaged bypass lever won’t allow the Cub cadet hydrostatic transmission not to move. Broke pump belt won’t allow the movement either.

Missing Spring also does it. The stretched spring causes sticking. An insufficient level of hydraulic oil causes it too. Air gets trapped in it, causing immobility.

My hydrostatic transmission got stuck, and I couldn’t use it during my work. The device didn’t move from its position and pushing it wasn’t working either.

I called the Cub cadet support team, and they told me the reasons why the hydrostatic transmission isn’t moving. I checked and moved my hydrostatic transmission after that.

Imagine working, and suddenly the hydrostatic transmission stopped. Now that’s a problem because it won’t move unless it’s fixed. And letting it stay outside for long isn’t good.

You have to move the hydrostatic transmission to get it inside. Check the fuel and see if it’s not working because of that. If the fuel is complete, the bypass lever may be turned. The bypass lever doesn’t allow the machine to move.

Check the spring, and it shouldn’t be too stretched. The spring can be missing too. The temperature of the hydraulic oil is very high and maybe old too. Air enters the transmission and gets trapped, and the cub cadet doesn’t move.

The pulley of the Hydrostatic Transmission may be worn out. The belt of the pump can be loose. Let’s see more.


There’s a lever in the hydraulic transmission that allows the fluid to move. The fluid puts pressure on the wheels to turn them. The transmission lever actually moves the machine manually. You can control the hydraulic pressure by yourself. The hydraulic If the lever is engaged, then disengage the lever.

You controlled the pressure manually, but now proper hydraulic pressure is needed, so disengaging will get the pressure. You may have a single lever or two, depending on the machine. If there are two levers, they are for different wheels, so disengage them both.

The lever can be at the back or front too. If the lever is engaged, the cub cadet won’t budge. You have to disengage the lever if the hydraulic pressure isn’t working. The lever isn’t hard to disengage, just use force to move it to the other side, and it’ll be disengaged.

Fluid level

The level of fluid in the hydraulics transmitter directly affects its movement. The fluid level needs to be packed to move the wheels. Check if the fluid is present in the required amount.

If the fluid isn’t present in the required amount, check if the fluid has leaked from somewhere. If it has leaked, fix the leakage. Get hydraulic fluid and add after the leakage is sealed.

The pressure will flow. If the fluid level has some other reason for being low, fix it. Check the level of the fluid by checking the guide, as some machines have sealed areas, so you need a professional to check the level of hydraulic fluid and fill it.

Fluid temperature

After the level comes the temperature of the fluid. The hot fluid is caused by the friction of fluid while working on a low amount. The low amount you have fixed already. But the temperature of the fluid, when high, causes extra damage.

The hot temperature precaution is giving the hydraulic machine some time to cool down. The low level of fluid cause it, so get the level in check. If the fluid is getting hot because of something else, get it fixed. A proper amount usually doesn’t allow the fluid to get hot.


The spring of the hydraulic press plays a significant role in the device’s movement. Without the spring, the device won’t move an inch. Check the spring if it’s present and not missing. If the spring of the hydraulic press is missing, get a newly matched spring.

The spring may be present, but the spring can be too stretched and worn out. A worn-out spring can’t pull like a good spring, and thus the device’s movement will be disturbed. Get worn and stretched spring replaced utterly.


The tensioner pulley of the hydraulic can also be worn out. The tensioner pulley is responsible for the movement of the lever and the wheel. You can set the lever with the pulley. The pulley won’t let the machine move. If the pulley is worn out, fix it.

The last word

Having the machine that works on a hydraulic system not moving in the middle is annoying. Force won’t work well n the device. So checking the lever and the fluid is a good start.

Check the spring and the pulley. Check the pump belt and see the damage. If the hydraulic machine isn’t fixed, call a professional.
