The John Deere Z930R is a zero-turn mower that was first introduced in 2013. It is part of John Deere’s Z Trak series of mowers.
The Z930R has a number of features that make it an attractive option for those looking for a high-quality mower, including a durable deck and powerful engine.
However, the Z930R also has a number of problems that have been reported by users.
That’s why we have compiled a list of common John Deere Z930R problems with their solutions.
Common John Deere Z930R Problems
1. Engine Sputtering
The John Deere Z930R engine sputtering problem is a common issue that can occur on these machines.
When the engine starts spitting, spatting, and sputtering, it can be difficult to determine the root cause of the issue.
In many cases, it is likely that the problem has something to do with the PTO. If you are experiencing this issue, try cutting the blades to see if this helps.
Additionally, you can open the gas cap when the car starts sputtering to see if the vent is bad. If you are still unable to determine the cause of the problem, it is likely that the PTO clutch is at fault.
This electromagnetic clutch has a magnetic coil and a motor that moves it. When you use the brake switch, the PTO engage lever will activate and move the clutch.
If the clutch is not functioning properly, it can cause the engine to sputter. To fix this problem, you will need to replace the PTO clutch.
2. Fuse Problem
Recently, there have been complaints about John Deere fuse problems with some of their equipment.
The most common issues seem to be with the Z930M, where the battery, starter, or fuse may not work properly. If your machine isn’t starting, it’s most likely due to one of these problems and you should try to jump-start the battery.
If that doesn’t work, then it’s probably a bad fuse and you’ll need to replace it.
Be sure to check the voltage of your battery before you do, as it should be at least 12.5 volts. If it’s less than 10.5, then you’ll need to replace the battery.
If you’re having John Deere fuse problems, be sure to check your voltage and replace any fuses as necessary.
3. Blocket Fuel Filter
The John Deere Z930R Blocked fuel filter problem is one that can be caused by a number of things.
The main culprit is usually water or dirt that has managed to get into the fuel system.
When this happens, all sorts of havoc can break loose. The engine may overheat, sputter, or even stall out. In some cases, the mower may not even start up at all.
If you are experiencing any of these problems, the best thing to do is replace the fuel filter.
This will clear out any blockages and hopefully get your mower back up and running smoothly.
4. Ignition Coil Problem
This is another common problem that John Deere Z930R owners are complaining about. There are a few things you can do to troubleshoot an electrical or ignition coil problem on a John Deere Z930R.
First, check the plug wires to make sure they are all attached properly and that none have come loose. If any have come loose, reattach them.
Next, use a meter to test the coils if you have a technical manual for your mower. Or you might test the two coils with the wires off ground to all locations and connectors to see if they test similarly.
If there is any issue with the ignition coil, it will need to be replaced.
5. Blades Keep Stopping
If your John Deere Z930R blades stop working repeatedly, the problem may be the PTO clutch disengaging.
It is also possible that there is a belt issue.
The most common cause of this problem is a malfunctioning safety switch under the seat. However, if it is a battery capacitation issue, you should also examine the battery.
If the blades turn on and then turn off quickly, it could be because they are drawing more power than the battery can give.
The seat switch may also not be working. You may need to replace the switch if it does not engage the blades when depressed.
You should never turn off your John Deere safety switches while the engine is running, so make sure that the switch is in good condition and properly functioning.
6. Transmission Leakage
The John Deere Z930R tractor has a high risk of leaking a hydrostatic transaxle transmission.
This transmission often leaks without any visible damage and it is usually the seal under the fan shaft that leaks.
The fix for this problem is often times covered by warranty, but in some cases, the owner may have to remove the transmission themselves and order parts from John Deere.
In most circumstances, the replacement will take between 4 and 8 hours to complete.
7. Transaxle Problem
The John Deere Z930R transmission is making a lot of noise, and the transmission fluid is contaminated.
The best course of action here is to try to troubleshoot and change the fluid yourself rather than take it to a dealer.
To start, make sure that the engine is turned off, the transmission key is removed, and the blades are in “disengage.”
Remove the battery and unplug it. Make sure the brake is engaged.
Next, remove the caps on each side of the transmission tanks with a socket wrench.
Be careful not to spill any fluid.
Then, using a funnel, slowly add fresh fluid to each tank until it’s full.
Replace the caps on each side of the transmission tanks, making sure they’re tight. Reconnect the battery and plug it in.
Turn on the engine and check for leaks. If everything looks good, put the blades in “engage” and take them for a test drive.
