Common John Deere Z225 problems

John Deere Z225 Zero Turn Problem


Generally, the zero-turn issue makes the device so unstable that it drops a steering grade or doesn’t return to its point.

When the spinning parts’ handle fails to attend to the mechanical issue, the handle can be jabbed or rammed, causing an uncomfortable experience for the user.

In the majority of cases, you can overcome these problems by using the simple hacks.


You need to carefully observe the tool from top to bottom to determine the problem.

You will need to add a steady connection over the steer if the handle is not fixable. Because when the connection gets loose, the steering may appear to be slipping.

If the handle is jammed, grease it to loosen it.

Part must be replaced if the tool gets rammed

John Deere Z225 starting problem

1. Problem

John Deere Z225 zero turn mower that wouldn’t crank, not even a click. After checking all the usual recommended reasons for a mower not starting, I finally discovered the problem after about 4 days of checking.


It was a bad mini interlock relay. The primary 12vdc coil was burned out. It’s amazing how something so small can cause such a big problem. I’m glad I finally found the culprit and was able to get the mower up and running again.

2. Problem

John Deere Z225 has trouble starting turning the key to start, you hear the starter engage. The engine tries to turn over but struggles. Sounds like the battery is low.

Bought a new battery, charged it then tried it. Same result. Tried jumping it off with my truck. It started and ran fine. The next time I went to start it – the same thing again. Tried to jump it off but no luck.


The symptoms described may indicate a bad starter. First, check all connections from the battery to the ground and from the battery to the starter. You may want to have the starter tested at Advance Auto or Auto Zone.

It will need to be removed from the mower, and I am not sure if Auto Zone, or Advance Auto can test small mower starters. They test the starter under load, so if you remove the starter and hook it up to a battery, it will run probably, but it will not indicate whether the starter is good or bad. It needs to be tested under load.

John Deere z225 Fuel is gushing through the carb


John Deere z225. Fuel is gushing through the carb literally filling up the cylinder and leaking into the crankcase


The fuel pump and the carburetor are the only things that can cause gas to get into the crankcase.

The fuel pump if leaking can allow the fuel to go through the vent line and enter the crankcase.

The carburetor (if the needle valve is leaking) will allow the fuel to continually fill the carburetor until it floods out the carburetor and then flows into the cylinder and then past the rings and into the crankcase.

If you have replaced the carburetor and the fuel pump then check the fuel solenoid on the bottom of the carburetor if your unit has one. Sometimes the solenoid will not seal off correctly and will allow the fuel to leak.

If your new carburetor did not come with a new fuel solenoid on the bottom of the carburetor then replace the solenoid.
