5 Common John Deere Z525e Problems and Solutions:

I’ve penned down the problems regarding John Deere Z525 e down below along with some common remedies to them- 

1. Faulty Engine

After a long period of constant usage, the engine of John Deere Z525 e starts showing some inconveniences.

Problems like a machine making knocking sounds, frequent pauses while functioning, losing its actual power are widespread among lawnmower users. 

If you’re worried about dealing with these issues, following the steps down below will help you-

  • Check out if you’re mowers’ brake pedal is okay or not.
  • Before doing anything with your JD Z525 mowers engine, make sure you’ve disconnected its connection.
  • Kindly ensure that your mower engine’s spark plug is adjusted correctly.
  • You need to replace your mower’s safety switch if it’s doing working.
  • Sometimes the engine shows problematic characteristics when the oil viscosity isn’t okay. So, balancing the proper consistency of the oil used in the mower can solve the engine issues. 
  • Inspecting the choke is a must if the John Deere Z525 mower consumes too much fuel. 
  • And if your mower engine overheats more often now, check out if the coolant system is doing alright. 

2. Gas Leaking inside the Air Filter

As a beginner, the user won’t know that tilting the gas cylinder can invite many problems. Many customers come to us and complain that their JD Z525e mower’s air filter became wet after they titled their cylinder. 

If you tilt your mower’s cylinder, the fuel inside it will penetrate inside the air filter. As a result, your air filter will drench in oil. Tilting or leaning your mower can cause leakage in the air filter of John Deere Z525e. 

If you ever go through this disturbing situation, kindly bring out the filter safely from the mower. And then dry the air filter to remove unwanted moisture due to fuel leakage. It’ll be okay then. 

And if the air filter leakage problem remains while the mower is upright, maybe the needle and float are stuck inside. Or maybe your JD Z525e needs a new needle valve and seat.

3. Cavitation Issues

Many problems cause Hydrostatic Transmission problems in a mower, and the Cavitation Issue is one of the fundamental reasons. You’ll notice a shudder during cut if a cavitation problem is evident in your mower.  

Cavitation problem mainly occurs when the engine’s blade can’t turn fast enough. As a result, the mower blade fails to suck up the water. You can identify cavitation clearly through the noise that it emits. 

For dealing with this John Deere Z525 e problem, what you can do is-

  • Park your John Deere Z525 on a flat surface before executing any step.
  • Don’t forget to set the brake and put the rear on a jack stand. 
  • According to the capacity of this mower, refill it with 64 oz. Oil.
  • Pull out the lever so that you can disengage the transmission. Then start the engine while sitting on its back. 
  • Moving the throttle control in a quiet position is necessary after that. Keeping the motion control lever in a neutral position is required by disengaging the clutch or brake. 
  • Push and pull the control levers accordingly to check the situation in both cases. Repeating these two steps thrice will purge unwanted air from the hydraulic transmission system.  

4. Mower Not Turning in a Side

Sometimes the new John Deere Z525e owners come up to us with this issue, and they tell us that they cannot turn their mower on the right/left side. Sometimes changing the filter inside the transaxle brings no change as well. 

It means you need to bleed the hydros. Start the process with cold hydros and run the engine as slow as possible. A cold hydro will ensure that all of the oil is at the bottom and the air is at the top. 

This process prevents the oil from frothing, and it makes the air hard to remove while in combustion with the oil. This issue can also appear if your hydro release is set in freewheel mode for that side. 

5. Black Smoke

JD mowers start emitting black smoke after some periods of constant use. But this is not normal. This issue appears when your lawnmower runs rich. This phenomenon is widespread among lawnmowers. 

Your lawnmower can emit black smoke if the fuel needle is flooded with Gasoline. So, make sure that your mower’s fuel needle is doing fine. 

Sometimes a mower puffs excessive black smoke because of rich fuel and air mixture. When a mower doesn’t get enough air, the combustion level becomes imbalanced. And when the combustion is incomplete, the unburnt energy turns into smoke. 

But the most common reason behind black smoke is clogged and unclean fuel filters. Cleaning the clogged air filter will prevent your John Deere Z525e mower from emitting black smoke.
