Top 6 John Deere 3039r Problems with Solutions:

Some of our clients have come out with some common John Deere 3039r problems worth considering. I’ve shortlisted 6 vital ones out of them. Let’s tell you about them below- 

1. Loose Blades

If the mower blades of your JD mower are too loose to function, you can’t shape the whole lawn with uniformity. A sharp mower blade with even settings is a must to chop off your mower grass. 

The experts have marked many reasons why your mower blade can be loose. It can be because of the broken bypass lock or if they’re unlocked accidentally. As a beginner, these problems may seem very diplomatic. But the remedies down below will make things easier for you- 

• Park your John Deere 3039r on a horizontal surface and disengage the battery connection for obstructing accidental activation. 
• Customize the cutting height of your mower for 3”. If you want to work under the deck of the mower, this specific height is good enough. 
• Make sure that you adjust the blades in such a way that it faces you. According to the experts, the distance between the mower’s deck and surface has to be 3”. If not, then you have to re-adjust the settings.
• Adjusting the screw and bolt levels are essential also.  

2. Transmission Failure

If you ask me about the most crucial problem regarding the John Deere 3039r lawnmower, I’ll tell you about Transmission failure. Transmission failure is related to mechanical power transforming into fluid power. 

The hydrostatic power of JD 3039r enables the mower to turn fluid power into shaft power. Unlike basic lawnmowers, this piece can serve you with spontaneous working hours.

However, there are chances of transmission failure with your JD 3039r if you’re not troubleshooting the problem. A decent session of maintenance every month is essential for preventing transmission failure. 

3. Overheating Engine

There’s no doubt that your John Deere 3039 lawnmower works hard in scorching heat to mow your lawn evenly. Hot summers in collaboration with long working hours can cause engine overheating problems. 

There are some circumstances under which your lawnmower’s engine can become too hot. If your engine is overheating frequently, the components of your engine can combust, expand or become weary. 

The reason behind engine overheating issue is put down below:

• Dirty Lawn Mower Engine– There’s no alternative to a clean engine for maintaining your mower’s condition. A dirty engine can block the air intake, fuel filters and hoses. 

So, cleaning your mower engine using a gentle brush is a must. Cleaning your engine using a soft-bristled brush will help the air to come inside. And by this, you can stop your engine from heating.  

• Low Oil Levels- Balancing the oil levels of your mower can safeguard your mower from several upcoming problems. Low oil levels are equally lethal the way using a bad grade oil is.

Always check the oil levels before starting your mower engine. And never your engine half-filled with residual oil for months. Before filling the engine with oil, let it cool down for a while.

• Air Penetrating the Fuel Filter- If your engine oil is mixing up with the air from the outside, it’s a threat for the engine’s health. Fuel in combustion with the air can overheat your engine and harm the components of it. 

You also need to check if your mower’s fuel filter or the cylinder hoses are alright or not. A dirty filter can cause damage inside the fuel. So, keeping an eye on it is necessary. 

• Cooling Fins or Shrouds Becoming Weary- If your mower heats up frequently, it can disperse heat and dislocate the actual position of your mower.

Maintaining the good position of these components is a must for keeping your engine cool while it overheats. Otherwise, the adversities can burn or melt the other parts of your mower. 

4. Black Smoke

If your mower emits excess black smoke, it is probably consuming more fuel than it has to. The mower experts recognize this problem as “the mower running rich”. 

This problem not only affects your mower’s performance, but also makes you spend plenty of riches on purchasing fuel. This problem appears when your mower’s carburetor gets flooded with fuel or the fuel filter has any leakage. 

Regular repairing session is the only way to save your mower from emitting black smoke. You also need to ensure that you’re cleaning the mower engine and its carburetor on time.

5. Issues with the Electrical System

One of the most common problems with the John Deere mowers is that they sometimes show electrical issues. The problem mostly relates to the battery. However, it’s nothing to worry about. 

When your mower’s battery is too weak to serve you with potential energy, this problem arises. Electrical turbulence may also occur because of ignition power issues. 

Replacing your old battery with a new one will instantly get you rid of the inconvenience. And if the problem still doesn’t resolve, your engine has broken down. 

You can also take it to a mechanic who can inspect and tell you about the problem. It’s never a big deal to ask for professional help.  

6. Abnormal Fuel Consumption

Do you think your mower is consuming more fuel than it normally does? There might be something wrong with your John Deere’s carburetor. Accidental leakage or clogged carburetor is the culprit behind such mishap. 

A clogged carburetor is behind the fuel overflow from the carburetor bowl vents and wetting spark plugs. The Ethanol fuels used these days tend to attract moisture from the outside.

And the metal in touch with the air, gets corroded easily. As a result, unexpected damage occurs inside the fuel tank and hoses. If you use a fuel stabilizer for your carburetor, the situation can come under control. 

Besides unwanted Ethanol deposits, you can also control unexpected fuel deposits. Green Part Store is a good source for purchasing your fuel stabilizer for John Deere 3039r.
