4 Common John Deere Z540M Problems and Fixes

The beauty of a mower like the John Deere Z540M is that it is compact, maneuverable, and hardy.

Zero-turn mowers like this are great for lawns with many features and changes in terrain, so it is built to be tough on rugged terrain.

However, regardless of this durability, you are bound to run into some running issues. Today we will delve into the four main issues and help you figure out how to sort out these problems at home.

Here are the four most common issues with the John Deere Z540M:

Engine Sputtering

The zero-turn maneuverability of this model makes mowing fast and efficient, but you may occasionally experience the mower sputtering and cutting out while you are executing a turn.

There are a few reasons this may be happening.

The Fix:

The first thing to check is the solenoid. Start by cleaning it and trying again to see if this solves the issue quickly and easily. If this doesn’t work, you will need to replace the solenoid.

If you know more about engines, you can try cutting off the head of the wire plugs into the main jet. Put it back and test if it works.

If neither of these fixes works, you may need to replace the fuel line.

Tracking Not Aligned

If you are driving your mower and you notice that it is pulling to one side rather than staying straight, then it is likely that your tracking is misaligned. This can make operating the mower very tiring as you struggle to keep it mowing on track.

Luckily, this is a super easy one to fix; all you need is a socket or ratchet wrench.

The Fix:

Sit in the seat and locate the screw beside your left leg. 

Turn the screw one full rotation clockwise if the mower is leaning left and anticlockwise if it is leaning right.

Deck/Blade Level Issues

When you first start up the mower, you may notice that the blades are not at the right level to be cutting the grass. 

The Fix:

This is likely because the deck or blade needs to be adjusted to the appropriate level for your lawn. Consult your manual and adjust them to the perfect cutting height for your lawn.

Breathing issues

To start, every engine needs fresh air to mix witty the gasoline. If this air is restricted, you will struggle to start the mower, or running may be restricted.

The Fix:

If the engine pulls in too much air, the bolts on the carburetor may be loose. Tighten all the screws up to restrict the airflow.

If not enough air is coming through, check for dirty air filters and clean or replace them.

Gardenaholic Tip: Caution! Zero-turn mowers like the John Deere Z540M can be dangerous on hills.

What Makes the John Deere Z540M a Good Mower?

So, now that you know the issues that you may encounter, we wanted to highlight some of the selling points of the John Deere Z540M.

High-performance engine

The Z540M is fitted with a 24HP, V twin engine that is air-cooled. This engine makes operating fast and efficient. It is also equipped with a rear engine cover that protects it during operation. 

Smooth Cutting

Along with the powerful engine, the deep mower deck stamping is what makes this model operate so smoothly.

The grass is cut on the first pass and is quickly pushed through the exit area, so the need for a second cut is not necessary, saving energy. This means you can cut uniformly, even at high speeds.

Comfortable operation

Many mowers are really uncomfortable to operate, but the Z540M is not one of them.

The seat not only moves back and forth but is also fitted with suspension springs underneath it, so your ride will be comfortable no matter what terrain you are tackling.

Two-stage filtering

As we mentioned above, an engine must be breathing to run at its best. The L540M does this with its two-stage filtering system. 

The foam filter stops any large debris early on, while the air filter stops smaller pieces.


Durability is a key feature in a ride-on mower like a zero-turn.

The Z540M is made from a heavy but comfortable steel frame with additional welded ribs to strengthen it. This is coupled with a powder coating that helps protect from rust.

These features make this model hardy enough to tackle many different terrains.
