1. Engine Surging

Engine surging is a common problem with Scag Liberty Z. In most cases, the mower will experience the problems at a lower and normal rpm.

Typically, a tractor engine requires a specific mixture of air and fuel to operate. When the ratio is incorrect, the engine will surge.

It is challenging to attain the correct combination when filters are clogged. Similarly, a defective gasket could allow air into the fuel system, resulting in engine surges.


  • Clean the air filter
  • Check and clean the fuel filter to ensure fuel flows smoothly
  • Check the gasket

2. Scag liberty z won’t start

The Scag Liberty Z is a good mower but often experiences a start-up problem. This could delay your programs and cause you unnecessary pain.

So it may be necessary to diagnose the  cause and learn how to deal with it. For instance, if the temperature is too low, the fuel mixture may not be good.

So, let the engine warm up for 5-10 minutes before you start using it. Warming it for some time allows it to operate well.

When the tractor is new, it only experiences many starting problems if it runs out of fuel. However, as the engine gets old, the problem becomes prevalent.

Consequently, you may need to troubleshoot the tractor often to identify the causes of starting issues and devise ways to solve them.

The mower may also experience difficulty in starting if the wiring or the solenoid is defective.

Also, if the PTO switch is not functional or the battery depletes fast, you experience starting problems.


  • Add additive to the fuel if the tractor has been in storage.
  • Charge the battery if depleted. (Recommended scag liberty z battery)
  • Check connections for loose wires or corrosion.
  • Check the spark plug. If faulty, replace it.
  • Replace the PTO switch if not working.

3. Leaking Gas Tank

A leaking gas tank can cause fire and accidents. Some Scag Liberty Z mower series experienced a regular leaking gas tank issue, forcing the factory to recall 4400 mowers.

Fortunately, the company recalled the series and rectified the issue. Presently, the problem is less prevalent.

But if you buy a second-hand mower, SZL48-22KT serial numbers K7100001- K7102353 or SZL52-24KT serial numbers K7200001-K7202020, you will likely experience the problem.


  • Avoid buying a mower with the above serial numbers.
  • Check the fuel pump and fuel system to ensure no breaches.
  • Check fuel filters for signs of clogging leading to poor flow.

4. Broken Fuel Gauge

Scag Liberty Z has reported many instances of a broken fuel gauge. Sometimes, the indicator will show the tank has no fuel even after filling it to the brim.

Sometimes, the gauge reading may not represent what is in the tank. Therefore, the problem makes it hard to track the fuel status or plan.

Usually, the fuel gauge may read incorrectly if the fuel-sending unit is defective. This component needs to measure the amount of fuel in the indicator and send the message on the fuel gauge.

Doing so keeps the operator updated on the amount of fuel in the tank. Also, it warns the mower operator when the fuel gets low to enable them to refuel.


  • Troubleshooting may help you fix the problem.
  • Consider taking the gauge to a fuel specialist.

5. Peeling Deck

After hundreds of hours of mowing, you may notice some peeling coming off the deck.

Sometimes, you may see some plastic dangling from and beneath the deck. Typically, this will happen when you work with Scag Liberty Z high-lift blade.


  • Work with the standard lift blade

6. Cutting Grass Unevenly

The Scag Liberty Z mower is meant for residential and home use. However, it is said to feature commercial-grade gear.

The gears make operators anticipate commercial-grade quality cuts. But over time, the quality deteriorates due to blade dulling, damage, or misalignment.

Other factors likely to make the mower cut grass unevenly include varying grass length and bent and unbalanced mower blades.

If the deck is improperly mounted or the spindle is bent, it will likely make the mower mow unevenly.


  • If the quality of the cut degrades, the first thing you may need to do is to check the blades. If they are dull, ensure to sharpen them.
  • If you have been mowing a rocky area, small stones could damage the mower. So the dings are likely to affect the quality of the cut. Thus, consider replacing the blades.
  • Do not cut wet grass.
  • Choose suitable blades for your Scag when replacing them.

7. Blowing Dust Cloud During Drier Weather

The Scag Liberty Z is a fast mower, but it kicks up enough dust from the front deck when you drive it on the dry or dusty ground.

So, as you mow, you will always move through a dust cloud, reducing visibility.


  • Buy and install a baffle accessory to solve the issues.
  • Desist from using high-lift blades and switch to low-lift blades.

8. Steering Problem

Learning how to steer a mower is critical if you are new to mowing. But even after mastering the art, you’ll need help to guide the mower in the right direction.

This may not be your fault, primarily if operating a Scag Liberty. It is normal for the machine’s steering to sometimes refuse to work.

You will thus feel that it is challenging to balance the steering wheel. This problem results in hardships in controlling the lawnmower and could cause an accident.

Additionally, the tire pressure could also be an issue. It is essential that you check the tire pressure regularly to avoid these problems.

Here’s a guide on the lawn mower tire pressure.

Also, if you use the mower regularly for extended periods, the steering wheels will likely become offset. It could cause issues and make it difficult to control and steer the steering in the right direction.


  • Remove the bolt and loosen the steering handle using a ratchet, a wrench, or a screwdriver. Once the handle comes off, unscrew and balance it off.
  • Tighten the bolt and screws.
  • Test if the problem recurs.

9. Sudden Turning Off

Lawnmowers that work like vehicles are likely to encounter this problem often. It happens when the engine oil is old or if there are loose wires. The mower could also turn off if it has a spark plug issue.

In other cases, turning off can occur when the fuel line is clogged and does not allow fuel to get to the engine.


  • Check and change the engine oil
  • If there are loose wires, fix them
  • Clean the fuel filters and fuel lines.
  • Clean the carburetor
