Owning a power tool like a John Deere diesel tractor is a huge help for small-scale farmers, but it’s also common to encounter transmission and hydraulic problems with this specific unit.
From my experience with the John Deere 1025R, I’ve compiled a list of frequent problems and the handy solutions I use to get my tractor back up and running efficiently.
Main Problems with John Deere 1025R Machine + Solutions
A John Deere 1025R machine encounters problems caused by a lot of factors. While some are simple issues, knowing how to troubleshoot them is important to keep your machine back on the road and running.
Some of the common issues are hydraulic oil problems, transmission, brakes, and faulty engine problems.
Problem #1: Engine Issues
John Deere is one of the best tractor brands, often regarded as a friendly machine, especially for farmers, but not when its gas engines are in a disarray.
I’ve come across instances where its gas engines can act up. Engine troubles tend to be a recurring theme with problematic tractors, and they can indeed snowball into more significant issues down the line.
The Engine Won’t Start
Faulty gearshift lever positioning can be at fault as to why your John Deere 1025r won’t start. The gearshift level should be in the high or low range, and if it falls short between these two, the John Deere engine won’t start.
To avoid this, always check how your gear level is positioned before starting your engine.
Oil Filter Won’t Function
Running your machine on a dirty oil or fuel filter will cause problems with your engine. Improper tire inflation on the other hand can prompt slow braking, both of which you want to avoid.
To avoid engine problems, always ensure that you check your batteries and that all the connections are correctly made. Loose wires will ignite problems on your engine, and keeping it clean and tight prevents possible problems. Damaged batteries should be replaced immediately.
Problem #2: Overheating Engine
Temperature affects a machine’s engine, and it’s a fact that most workers aren’t aware of. I’ve seen firsthand how it can lead to overheating. And let’s not forget about accumulated debris on the radiator fins; that’s another culprit I’ve observed causing engines to heat up more than they should.
Apart from these common reasons, another cause of overheating engines is poor fan belt adjustment. To prevent this, make sure that your belt is always in a taut position.
One paramount on John Deere engines is the regular cleaning of the radiator fins. Doing this regularly will prevent the accumulation of debris, which often is the trigger of overheating engines.
Also, keep your fan belt tight and invest in a coolant especially if you’re using your engine frequently.
Problem #3: Transmission Problems
Leaking transmission fluid is one of the common problems people experience with their John Deere machines. What’s worse is that you can’t move your machine even if the engine is running.
Transmission problems are often a complication of a faulty gearshift lever or stubborn oil. Both these can trigger your machine to stop running. Luckily, here are quick fixes you can make:
Neutral Shift Lever Positioning
Check the neutral shift lever position. It should be in a high or low-range position all the time.
Cold Transmission Oil
From my time working with machinery, I’ve learned the importance of keeping the oil warm for smoother fuel movements. Especially in winter, it might take some patience, but I can’t stress enough how crucial it is to avoid leaving your transmission oil cold. Doing so can prevent a host of complications down the line.
Low Transmission Oil Level
Always check your oil tank, and if the oil falls below the minimum fluid level, then you should fill it out right away, as not doing this can spark damage or faults on your engine. As much as possible, don’t leave your transmission oil low.
Inspect the gearshift lever and check how it is positioned. Keep the lever upward or downward, instead of leaving them in a neutral position. If the problem still persists, you can check the oil level. There should be enough oil to run the machine, or it will stop and cause issues.
Problem #4: Brake Malfunction and Steering Issues
Brake problems are nuances you should avoid as they can prompt accidents if not taken care of right away. You’ll notice brake problems in form of squeaking sounds produced by your JD tractor.
Brake leaks and malfunctioned steering systems can be deadly, so it’s best to troubleshoot once these telltale signs happen. This way, you avoid encountering related John Deere 1025R problems in the future.
Regularly inspect your oil filter as damaged filters can cause brake issues. A damaged one can lead to brake troubles. And speaking of brakes, another piece of advice I’ve picked up over the years: keep an eye on those tires. Underinflated tires can be a sneaky culprit behind brake failures.
Problem #5: Hydraulic System Malfunction
Hydraulic problems are common with John Deere tractor models simply because a tractor will lose speed and performance throughout use, like most engines.
Alterations in your oil and pressure cause the hydraulic mechanism to malfunction, compromising the engine’s performance.
It’s also easy to determine if the hydraulic system is what’s causing your problem, because it gets too noisy, and moves slower. This may be caused by burning fluid, or a clogged filter, or may also be a result of using the wrong hydraulic fluid.
Bad Machine Performance
Altering the hydraulic fluid pressure can compromise the performance of John Deere tractors. To fix it, inspect the hydraulic oil filters, and regain its performance by draining and filling the hydraulic fluid.
When pure hydraulic oil alters the density and pressure of your John Deere unit, it will cause the speed to decrease. Often too, its speed will deteriorate due to prolonged use. To correct this problem, simply drain the tractor’s hydraulic system, and replace it with the correct oil.
You don’t need a professional to fix a hydraulic problem. Simply drain the hydraulic system, replace it with the right fluid, and refill it accordingly. You can also reset and use the same step if you see that there’s nothing wrong with your fluid at all.
Problem #6: Electrical System Issues
One of the common causes of electrical system issues is damaged batteries. When I spot corroded terminals or find that a battery just isn’t holding up, I know it’s likely to introduce high current resistance and lead to electrical issues.
Clean the terminal often to avoid corrosion, and always ensure that the electrical belt is tight. Replace faulty batteries to prevent connection problems.
Factors To Consider
Problem #7: Deck Leak
If you’re one of the unlucky ones who get a JD 1025R with deck leaking oil, frustration would have been eating you up. Chances are, you bought a tractor that has a faulty hydraulic cylinder causing the annoying leaks.
Even simple problems in the hydraulic system can be annoying, moreover, deal with unnecessary leaks.
Seek mower models that are compatible with compact utility tractors. It also comes with mulching kits, to match your machine.
Problem #8: Fuel System Issues
A steering column, system, faulty engine, and faulty fuel filters are common culprits to defective fuel systems. Inflating your tire improperly can also be a reason.
Unlike the common reasons, this fuel system problem doesn’t cause effects right away. Instead, it deteriorates your machine over time, causing clogs, poor performance, and efficiency.
The best way to fix a fuel system problem is to tap a mechanic or professional because trying to fix it on your own with very little knowledge will cost you your prize tractor. This will prevent any damage to occur on your John Deere Tractor.
Other John Deere 1025R Issues That You Need To Watch Out For
Loader and Tiller
When I bought my John Deere 1025R tiller and loader, I too faced issues with the hydraulic system, as many others have. It seems to be a common occurrence.
The fluid driving the machine’s motion often causes difficulties, causing it to slow down and cause problems with the tractor. A faulty steering system is often caused by the following:
Often, wrong installation or blown fuse can cause a faulty PTO  clutch or hydraulic pump. This happens due to clogged hoses, fittings, and broken solenoids. Change the brakes on the PTO and ensure that the hoses are clean.
I’d suggest hiring a mechanic to tackle these frequent issues. However, from my experience, regular cleaning and maintenance can often prevent these problems from cropping up.
The rock shaft turns half to lift cultivators. If you have loose rings, it can cause the rock shaft to be shaky.
Replacements can be a little hefty, and this specific problem requires the expertise of professionals. Don’t try to save it by yourself, because replacing the shaft is dangerous if done erroneously.
