So, you might believe that the problems of your Toro Zero Turn lawn mower can not be rectified all by yourself. If so, then you are totally wrong. 

Let’s dive into some fundamental troubleshooting and sustenance tips that will assist you in solving some of the essential hydraulic difficulties of your mower.

2. Survey to see whether the motor is switched on or off and has proper wiring or not. Again, find out whether the motor is generating any unusual sound or not.

3. Take off the pump and assess its interior parts. Confirm that all the parts are appropriately operative and installed correctly.

4. Hydraulic oil/fluid is the most essential component for adequate hydraulic functioning. Make sure its color, level, and viscosity satisfy the needed specifications.

5. Examine all the lines for possible leaks and re-establish all connection points. 

If a leak prevails somewhere, then the oil reservoir will dry out at some level. And air may get in, bringing about the slowdown of the mower and can even make it halt after some time. 

Also, inspect for the hydraulic hoses.

6. If you still can’t uncover the problem, it may be the hydro that is failing. 

This particular component frequently dies out without giving any previous sign. But before changing it, you should heed two steps. 

Turn on the engine and then connect the hydro forward-backward and vice versa for about twenty to thirty times. 

This will be handy in eliminating any air that is caught up inside. But if that does not work, the hydro component must be the reason.

Aged hydraulic fluid is the most popular reason for hydrostatic failures. With time, hydraulic oil loses its innocence because air and moisture pollute it. 

This old or entrained oil indicates inadequate hydraulic properties related to fresh oil.
