Let’s explore some of the most common complaints about the John Deere 757 and try to provide some solutions.
1. The Hydraulics system
The hydraulics system is often the first to malfunction on the John Deere 757. It can be caused by different issues, including air in the system, plugged filters, or worn seals.
To fix these problems, replace the filters and clean the system of any dirt or debris.
If that doesn’t work, replacing the seals or rebuilding the pump may be necessary. It’s also essential to check for leaks in the system and repair them as quickly as possible.
Here are some critical steps to follow when troubleshooting hydraulics problems on the John Deere 757:
- Replace or clean any filters that are clogged.

- Replace any worn seals or rebuild the pump as needed.
- Test the system after repairs have been made to ensure proper operation.
2. Poor performance
Another common issue with the John Deere 757 is poor performance. Numerous things, such as worn piston rings or a clogged air filter, can cause this. It can also be caused by low oil levels or contaminated fuel.
To fix these issues, you should first check your fuel levels and the condition of your air filter. If either of those is the cause of poor performance, they should be replaced as soon as possible.
You should also check your oil levels to ensure they are at the proper level. If the oil is low, you should top it off before continuing with other repairs.
Inspecting and replacing any worn piston rings is essential, as this can often cause poor performance. Finally, you may need to have the engine tuned up if all other repairs have failed.
3. Electrical issues
Electrical issues are another common problem with the John Deere 757. Loose connections, faulty wiring, or bad fuses and relays can cause these.
To fix these problems, you’ll first need to inspect your wiring and connections for any signs of damage or wear. If you find any loose connections, you should tighten them before continuing with the repairs.
You’ll also need to inspect your fuses and relays for signs of wear or damage. If they are damaged, you must replace them as soon as possible. Finally, testing the system after all repairs have been made is essential to ensure proper functionality.
Here are some important steps to follow when troubleshooting electrical problems with the John Deere 757:
- Inspect wiring and connections for any signs of damage or wear.
- Replace any damaged fuses or relays.
- Test the system after repairs have been made to ensure proper operation.
4. The Transmission and gearbox
Transmission and gearbox problems can also be common on the John Deere 757. These issues are generally caused by wear or damage to the system’s gears, bearings, seals, or other components.
To fix these problems, first, you must look at all the parts for any noticeable wear or damage. It’s vital to replace any worn or damaged parts as soon as possible.
You should also check the fluid levels in the transmission and ensure they are topped off. If the fluid is low, you should top it off before continuing with other repairs.
Here are some essential steps to follow when troubleshooting transmission and gearbox problems on the John Deere 757:
- Inspect all components for any signs of wear or damage.
- Replace any worn or damaged parts as soon as possible.
- Top off fluid levels if needed.
- Test the system after repairs have been made to ensure proper operation.
5. Excessive vibration
Excessive vibration can also be an issue with the John Deere 757. Worn or damaged gears, misaligned parts, or bearings can cause this.
To fix these issues, you should inspect your gears for any wear or damage. If any are found, they should be replaced as soon as possible.
You should also check for any misaligned parts and realign them if necessary. Finally, you’ll need to inspect your bearings for any signs of wear or damage.
If they are damaged, you should replace them as quickly as possible.
Following these steps can help ensure that your John Deere 757 runs smoothly and without excessive vibration.
6. The Fuel system
Many John Deere 757 owners experience fuel system issues, such as a lack of power or excessive fuel consumption. The most common causes of these problems include clogged filters, the air in the system, and faulty injectors.
To fix these problems, you should check the filters and replace them if needed. You should also inspect the injectors and replace any that are faulty.
If the problem persists, rebuilding or replacing the fuel pump is essential. Additionally, you should check for air leaks in the system and repair them as quickly as possible.
Here are some key steps to follow when troubleshooting fuel system issues on the John Deere 757:
- Check and replace any clogged fuel filters.
- Inspect the injectors and replace any that are faulty.
- Rebuild or replace the fuel pump as needed.
- Test the system after repairs have been made to ensure proper operation.
7. Low oil pressure
Oil pressure can drop due to low oil levels or worn-out engine parts such as pistons and bearings.
If your oil light comes on while driving, stop immediately and check your oil levels; if they’re low, fill them up before continuing your journey.
If this doesn’t solve the problem, you may need to have a mechanic check your engine components for further diagnosis.
8. Leaking fuel tank
A leaking fuel tank can cause all sorts of problems, from poor performance to hazardous fumes in the cabin.
If you notice any signs of leakage (e.g., wet spots on the ground), take immediate action to prevent further damage down the line!
The best way to do this is by checking all fuel lines for cracks/leaks using soapy water (or specialized repair kits available at auto stores).
This should be before replacing any damaged pieces as necessary – either from a dealer or online store, depending on what part(s) you need!
9. Ignition switch failure
This can be caused by worn-out ignition switches or wiring harnesses damaged by corrosion over time.
If your engine isn’t turning over when you start it up, it’s likely an ignition switch issue that needs addressing urgently, as it could cause severe damage if left unchecked for too long!
To fix these problems, you’ll need to inspect the wiring harnesses and replace any corroded or worn-out ones. You should also check for loose wires and reconnect them if required.
Additionally, you’ll need to inspect the ignition switch and replace it if necessary. Test the system after repairs have been made to ensure proper operation.
10. Overheating
The John Deere 757 is prone to overheating due to its small cooling system capacity; this can be caused by low coolant levels or clogged radiators/cooling fans that can’t draw enough air through them.
To fix this problem, ensure your coolant levels are topped off regularly.
If that doesn’t solve the issue, you may need to have a mechanic flush out your cooling system and replace worn-out parts, such as hoses or radiators/fans, that have become blocked by debris or rust build-up over time.
11. Worn-out belts/pulleys
All belts/pulleys must be checked regularly for wear and tear; otherwise, they could snap without warning – leading to potentially fatal consequences!
To ensure maximum safety, always ensure these components are replaced every few years (or whenever they show any sign of wearing out). Using genuine OEM parts from reputable sources – either online stores or dealerships, depending on what part(s) you need!
