The 5 Most Common Problems Associated With the John Deere 4066R
The following five concerns are the most common problems associated with the John Deere 4066R and its occasional malfunction. In each section, we’ll briefly discuss each of these issues and highlight a few simple steps that you can take to manage them quickly and appropriately.
Battery Issues
The Problem
The battery is essential on any vehicle but can be really problematic on many John Deer 4066R models. That’s because it has a tendency to poorly charge. Many John Deere owners report this issue not just with the 4066R model but with others, like the 2305 tractor.
Sometimes, this problem is a very minor issue. The terminal clamps may simply not be connected tightly enough or may shake look as the tractor runs. These clamps may also get corroded with time and experience trouble providing a smooth electrical flow.
Other issues include worn or loose battery cables or damage to the battery itself. It is important to address each of these issues in order before replacing the battery. Doing so can ensure that you aren’t throwing away a perfectly good battery with many years of life left.
The Fix
Start by cleaning the terminal clamps and replacing them if cleaning doesn’t stop this issue. You may then went to repair or replace any worn or damaged cables and recharge your battery to see how well it runs. After these steps, it is time to simply put in a new battery and move on.
Noisy Transmission
The Problem
Noisy transmissions are more than just an annoyance: they can be a sign of serious damage. For example, there is a chance that poor fluid maintenance and other common mistakes have caused your transmission serious damage that make it nearly impossible to run smoothly.
If you notice a noise when you first buy your transmission, it might just be the gear teeth. Sometimes, a new transmission can have sharp gear teeth that need to wear down a little. That’s usually not a big problem but can be an issue if the gear is not properly balanced or installed.
Furthermore, simple age and wear can cause your transmission to sound loud. This problem often occurs on the John Deere 4066R because it is used for such heavy work so regularly. As a result, it is important to pay attention to any problems that may develop while running it.
The Fix
Fixing a transmission may include replacing an internal gear to ensure that it runs properly. You may also need to change the fluid to make sure that your tractor runs properly. Changing the fluid should be easy enough for most tractor owners. If these fixes don’t work, call a mechanic right away.
Poor Blade Operation
The Problem
Your John Deere 4006R’s blade should run smoothly and level with the ground to spread seeds and soil with ease. However, your blades may operate poorly and cause your tractor to struggle. This can make your tractor seize up on the ground and struggle to drive properly.
Even worse, it can cause issues with your farming that can cost you money and time. This problem is usually due to wear and tear concerns. Your blade will get old with time and may need to be replaced, especially if you have a rough driving situation that damaged the blade.
A dull blade is a serious issue because it can cause damage to your motor. How? By causing the tractor to work harder to do basic tasks. As a result, it is important to take this situation very seriously and to sharpen your blade to keep it moving effectively through the soil.
The Fix
If you feel comfortable tackling this step on your own, you can easily sharpen the blade using various sharpening tools. However, we strongly suggest taking it to a blade sharpening professional because they can do the job without putting you at risk of cutting yourself at the same time.
Engine Problems
The Problem
Have you ever tried to start your John Deere 4066R and found it simply won’t turn over? You’re not alone. This very common problem is frustrating and may come and go. For example, you might not notice this issue for weeks and then have days when your tractor won’t start.
What is going on here? There are a few problems that may be plaguing your diesel engine. Diesel vehicles like this tractor need a good fuel filter to run smoothly. If your filter is dirty, it might cause the fuel to run poorly and can even affect how well it runs.
Even worse, you might have a problem with the fuel injection pump. This pump helps to keep your system running smoothly but can be affected by engine heat. Diesel engines tend to run very warm, which can damage the fuel pump and make it run improperly.
The Fix
Start by replacing your fuel filter with a clean one and letting your engine sit. Try to start it to see if it works. If not, you can replace the fuel injection pump by going under the hood and removing and replacing it. This small part might seem minor, but it can cause real engine problems if not managed.
Steering Concerns
The Problem
Your John Deere 4066R should steer smoothly without difficulty. However, you may notice rough steering that makes it hard to handle your tractor. You may also notice that your wheel wanders in a specific direction. All of these problems are indicative of steering issues.
For example, a rough-handling tractor may indicate airlocks in the steering systems. There should be no air within the steering pump but some can get in the pump. When this happens, the steering is going to run awkwardly and may cause your John Deere to stutter.
When the steering wheel wants to go in a specific direction, that is a symptom of a real problem with the power steering system. Fixing these issues is a bit more challenging than getting rid of airlocks.
The Fix
Start by finding your steering pumps and to carefully bleed out the air using the release valve. If this doesn’t fix the problem, you can replace the power steering gear. We suggest working with a mechanic on this problem because a mistake could be very costly.
