Spartan Mower Problems Starting

If you have ever tried to start a lawn mower, you know it can sometimes be a frustrating experience. 

There are several things that could go wrong – from bad wiring to a weak battery. In some cases, the problem might be as simple as needing to clean or replace the spark plug or air filter. 

Other times though, diagnosing the issue may be more difficult. 

For example, some customers report their mowers will not start because of an LCD circuit board issue. 

While this may seem like an unlikely cause at first glance, replacing the board has been known to fix the problem temporarily in many cases. 

If your mower is still giving you trouble starting up after trying all these tips, it may need professional servicing

No one enjoys the process of trying to start a Spartan mower, only to have it fail due to some underlying issue. 

Whether the problem is something as simple as a dirty spark plug or more complicated like an LCD circuit board issue, customers can get frustrated quickly. 

In some cases starting a Spartan mower is simply a matter of trial and error until the right solution is found but oftentimes it’s best left to professionals. 

By understanding some of the most common reasons why mowers don’t start up, you can be better prepared next time you go out to tackle your lawn.

Mower Deck Noise

Spartan mowers are designed to run quietly, but some customers have reported that their mowers have been making noise. In most cases, this is due to a loose blade or worn-out bearings. 

If your mower is making unusual noises, it’s important to get it checked out by a professional mechanic as continuing to use a mower with these issues can be dangerous. 

Spartan zero turn lawn mowers are of high quality and backed by great warranties. So if you do experience any problems with your Spartan Mower, customer service will always be happy to help sort things out for you quickly and easily. 

Because at the end of the day – they want you to enjoy using your Spartan Lawn Mower just as much as you enjoyed picking it out in the first place!

Spartan Mower Cutting Uneven

The most common problem with Spartan mowers is an uneven cut, which can be caused by a number of different factors. 

Dull blades are the most likely culprit, as they will leave streaks in the lawn and result in an overall poor cut. 

Sharpening the blades should be the first step in troubleshooting this issue. 

Another potential cause for an uneven cut is build-up of grass clippings underneath the deck. 

This can impede blade movement and prevent proper cutting action from taking place. To remedy this, simply clean out any debris that has accumulated beneath the deck. 

In some cases, tires may also be to blame for an uneven Cut job being done by your Spartan mower – if they are underinflated then it will throw off balance and make it difficult to achieve a level trim across your lawn. 

Be sure to check tire air pressure frequently (according to manufacturer guidelines) and inflate/deflate accordingly so that each tire has equal amounts of air pressure.

Lastly, one final thing you want to check is whether or not the actual deck itself is spinning level side-to-side and front-to-back; if it isn’t then naturally this too will result in a lopsided cut every time around your yard.

Cleaning Spartan Mower Deck

In order to ensure that your mower performs at its best, it is crucial to keep the mower deck clean. 

For zero turn mowers, the deck is where all of the mowing action takes place. As a result, debris and lawn clippings can easily accumulate over time. 

If these materials are not removed on a regular basis, they can cause corrosion to the mower deck. 

In addition, the clippings may gradually accumulate and jam the discharge chute, restricting ventilation. As a result, it is important to clean the deck after each use in order to prevent long-term damage. 

For Spartan mowers specifically, keeping the deck clean is essential in order to maintain optimal performance. 

Consequently, it is important to be diligent in deck maintenance in order to protect your investment.

Keep Mower Blades Sharpened

If you’re a lawnmower owner, then you know how important it is to keep your mower blades sharp. 

Not only does it ensure a clean cut, but it also helps to prevent tearing of the grass. Sharpening the dull mower blades at least twice a year is required for a clean cut. 

If you’ve never done it before, don’t try to sharpen the blades yourself. Instead, take it to Spartan Mower Dealer or local mower repair shop. 

Not only will they be able to sharpen the blades quickly and efficiently, but they can also check for any other potential problems with your mower.

Tire Pressure

Tire air pressure is important for several reasons. Having the proper tire pressure ensures an even cut when mowing your lawn. 

If one tire is higher than another, it can result in an uneven deck on the mower and ultimately, an uneven cut. 

Furthermore, having properly inflated tires helps to prolong their life – they will last longer before needing to be replaced. 

This not only saves you money in the long run, but also time spent replacing them more frequently. 

Additionally, checking your mower’s tire pressure regularly is a good way to prevent problems before they start; by catching a tire that is beginning to lose air pressure, you can avoid flat sand other issues that may occur if left unchecked


Not all Spartan mower problems are life ending, and like all machines will eventually have some issues. 

However, with most Spartan mower problems are actually quite simple to fix. One of the most common complaints is that components start to wear out quickly. 

This isn’t really a problem with the machine itself but more an issue of user error. 

When using any lawnmower – regardless of brand – it’s important to follow the proper maintenance procedures as outlined in the owner’s manual. 

This includes things like regularly changing the oil, checking tire pressure, and making sure there is no debris under the deck which can cause premature wear on blades and other parts. 

Another common problem is flat tires or incorrect tire pressure. Most people don’t realize that different terrains require different tire pressures for optimum performance from their mower . 

The rule of thumb is: softer soils need less psi while harder surfaces require more psi . Again , this information can be found in your owner ‘s manual.
