What Happens When the Husqvarna Zero-Turn Mower’s One Side Does Not Work?

Many issues can arise when a Husqvarna zero-turn mower only functions on one side. These are:

  • Unable to turn: It will be more difficult for the mower to turn. Due to this, turning or steering the mower around obstructions may be challenging.
  • Unable to control: Controlling the mower will be more challenging. So, the mower operator must exert more energy to steer the Husqvarna zero-turn mower. It will therefore be more prone to stray from its intended course.
  • Damage to the grass: The mower might harm the grass. The mower’s blades can drag across the lawn if it can’t revolve properly. The grass will suffer harm as a result.
  • Tipping over: It will be more likely for the Husqvarna zero-turn to tip over if one side does not work. This is because the mower’s balance will be off. Therefore, the working side will bear more of the weight.

It’s crucial to cease using the mower right away if you encounter any of these issues.

Husqvarna Zero-Turn One Side Not Working: Reasons and Fixes

The Husqvarna zero-turn one side may not function for some reasons. The causes and fixes are as follows:

Low Hydraulic Fluid Level 

Low hydraulic fluid levels are one of the most frequent causes of one side of a Husqvarna zero-turn mower not functioning.

The hydraulic system may malfunction due to insufficient fluid. So, you might be able to move one side unevenly or not at all.


  • Turn off the mower’s engine and place it on a level area.
  • Find the hydraulic fluid reservoir.
  • If the fluid level is low, check it and top it off with the necessary amount of hydraulic fluid.
  • Start the engine after adding fluid, and then test the mower to check whether the issue has been fixed.

Misaligned Wheels

While mowing, you might hit obstacles. It will lead to the wheels becoming out of alignment. Also, mowing on unleveled ground increases the risk of misalignment.

Wheels may fall out of alignment as well. This happens because of poor adjustment during maintenance. Wheel misalignment might make it more difficult to steer and operate the mower. The wear of tires can also be uneven.


  • Visually compare the positions of the wheels to check their alignment.
  • Verify that the alignment of each wheel is correct.
  • The wheels should be correctly aligned using the adjustment mechanisms. 
  • Replace wheels that have been damaged or deformed.
  • When mowing, be aware of obstructions.

Uneven Tire Pressure

The balance of the Husqvarna zero-turn mower might be impacted by uneven tire pressure. As a result, one side will function less well than the other.


  • The best course of action is to check and adjust each wheel’s tire pressure.
  • Follow the manufacturer’s recommendations for adjusting the tire pressure.
  • While adjusting the pressure, equally inflate the tires.
  • This will promote balance and ensure better performance.

Damaged Hydraulic Pump or Motor

One side of the Husqvarna mower may not operate due to damage to the hydraulic pump or motor. Wear and tear may be the reason for this. 

Additionally, the parts may sustain serious damage if you run into any objects while mowing.

Air in Hydraulic System

This problem is experienced by some users as a result of air bubbles in the hydraulic system. It may obstruct fluid flow.

As a result, the Husqvarna zero-turn mower’s one side might not operate as it should. Leaks or poor maintenance are two reasons why this may occur.


  • Bleed the hydraulic system to get rid of bubbles in it.
  • For detailed instructions, refer to the mower’s instruction booklet.
  • To remove the air, you should open the bleed valves while the mower is running.

Clogged Hydraulic Lines

Hydraulic filters and pipes can clog up over time. The flow of fluid to one side of the mower can be impeded by dirt or old hydraulic fluid.


  • Check the hydraulic lines and filters for obstructions or clogs.
  • Clean them up or replace them as necessary if you find any.
  • You can avoid this problem by performing routine maintenance.
  • Also, change the filters as instructed by the manufacturer.

Irregular Weight

The balance and functionality of the Husqvarna mower might be impacted by uneven weight distribution. If you are heavier on one side than the other, this can occur. The mower may also tip over to one side if it is not loaded evenly.


  • Ensure that the mower’s weight is distributed evenly.
  • If required, you should remove any extra weight from one side.
  • When employing attachments or accessories, evenly divide the weight.

Damaged Belt

Belts may inevitably deteriorate and deteriorate over time. Too-loose or too-tight belts may prematurely wear out.

If the belts on your Husqvarna zero-turn mower are worn out, steering may be challenging. This issue can also be brought on by belts that detach from the pulleys.


  • Check the belts frequently for signs of wear and damage.
  • Make sure the tension on the belts is correct.
