Characteristics Of Problems With John Deere Zero Turn Mower Steering 

You can quickly tell when the steering on your John Deere zero-turn lawn mower needs to be checked, fixed, or replaced based on a few critical signs.

So, let’s find out more about why there are steering problems. –

(1) Undercarriage and deck

If the slope is steeper than recommended, the mower can get stuck on the ground. So, your mower won’t be able to turn and won’t go forward or backward.

(2) Slipped Steering Gear

Once, a customer said that he hit a brick wall with his zero-turn John Deere mower. And this event had shaken the gear loose. This gear controls the steering. So, he was having trouble turning the wheel.

(3) Increase/Decrease Drive Wheel Speeds

If the drive wheel on one side of the mower is turning slower, it could cause the mower to lean in that direction.

(4) Incorrect Tire Pressure 

One of the most common reasons for a steering problem is a problem with the tires. Some people had trouble steering because their tires were too full or too empty.

(5) Debris

One of the main reasons for steering problems is that they aren’t taken care of regularly, or things get stuck on the parts.

String or long weeds can get wrapped around the shaft of your blade. It can make it harder to steer. Check to see if anything can get stuck in the other parts.

(6) Wheel Bearings Issue

A customer said that the mower’s wheel bearings were not taken care of by the person who owned it before him. They moved from side to side.

Over time, it got harder to steer the John Deere lawn tractor. Because the bolts can come loose or the bushings can wear out. This could stop the gears from engaging, which is needed for easy steering.

John deere zero turn one side not working

You can check a few things if one side of your John Deere zero-turn mower isn’t working. Make sure the deck is level first. If the deck isn’t level, the blades might hit the ground in different places, stopping one side from working.

You can use a level or measure from the ground to the top of the deck on both sides to see if the deck is level. If the deck isn’t level, you’ll have to fix it so that it is. The belts are another thing to check.

On a John Deere zero-turn mower, the blades are moved by belts. If the belts are too loose, they can slip and stop turning the blades. You’ll have to check the belts’ tension and tighten them if they’re too loose.

Last but not least, check the blades. If the blades are broken or not sharp enough, they can make one side of the mower stop working. You’ll need to check the blades and either sharpen them or replace them if they’re broken.

If you’ve checked all these things and the mower isn’t working right, you may need to take it to a John Deere dealer or service center to fix it.

What does a steering damper do on a zero-turn mower?

A zero-turn mower has a device called a steering damper that is attached to the steering shaft. It is used to smooth out the steering input from the driver, making turning more accessible and controlled.

Usually, the damper is adjustable, so the driver can set it to the level of steering dampening they want.

What To Do When You Detect John Deere Zero Turn Mower Steering Problems?

If you find yourself in any of the above situations, make sure to follow the steps below to fix the problem:

(1) Reducing the Wobble

Sometimes it’s hard to steer. The tie rod can break in this way. The rod goes between the left-hand lever and the hydrostatic drive for the left rear wheel.

This helps move the short lever forward, making the balance better. You might need to get a new one.

Your steering may also be off because a wheel spindle is broken or bent. The wheel spindle may also need to be replaced.

(2) Fixing the wheel speeds

When you push both steering levers forward, if your John Deere mower turns to one side, you need to either slow down the faster wheel or speed up, the slower wheel.

To do this, you need to follow some steps:

• Find out which way your mower goes (left or right).
• Loosen the nut on the adjustment bolt on the device.
• To change the speed, turn the adjustment bolt clockwise to make the steering lever move less or turn it counterclockwise to make the steering lever move more.
• Put the nut back on.

(3) Adjusting the Speed Nut

When you move your steering arms, you’ll see a bolt that stops the arm from moving forward. Sometimes the arm needs to be tightened or loosened so it can move in a broader range.

You can loosen the nut with a wrench and turn the bolt by hand. Move the bolt to the right to slow down the bolt as it comes out. Turning it to the left will go further into its housing, making you go faster.

(4) Fixing the tire pressure

To fix the problem, check the operator’s manual to ensure the tires have the correct air pressure. Then, use a tire gauge to check each tire.

If the tire’s psi isn’t correct, you can either let the air out of the tires or pump air into them until you get the right amount of psi in the manual.

(5) Adjusting the steering levers 

The steering will sometimes lean to one side. It will change how it feels to mow. To get rid of this –

• Adjust the height of the handle
• Adjust the axis of the lever

(6) Maintenance 

To fix the problem and make the blade last longer, you need to eliminate all the junk and other things wrapped around the blade shaft.

Also, it would help if you stayed away from muddy areas. First, you need to look at the place. Then you need to set the height to what you want.

(7) Bolts fixing 

With engine bolts, the mower won’t shake as much when you steer it or run the engine. But sometimes, the bolts work themselves loose. Lock down the engine bolts and replace any that are missing.
