1. Not Cranking 

One of the most frustrating problems you may encounter with your JD LT180 is the cranking challenge, or you are not hearing the click sound. It generally indicates your tractor’s battery is out of service or there is a bad connection somewhere between the battery and starting engine. 

Here are the steps to resolve it.

Step 1: Check the battery first. If the battery is old or not charging properly, consider replacing it, which will generally cost you around $60-$80. Also, be sure the battery connections are tight and free of corrosion. 

Step 2: Inspect the spark plug. A fouled or damaged spark plug can prevent the engine from starting. Clean or replace the spark plug as needed.

Step 3: Verify that there is sufficient fuel in the tank and that the fuel lines and filters are clean and unclogged.

Step 4: Check all safety switches, such as the seat safety switch and the mower deck engagement switch, to ensure they are functioning correctly.

The video below will give you some ideas to fix the cranking issues of the JD LT180 tractor.

2. Engine Performance Issues

If your John Deere LT180 is experiencing a loss of power or rough idling, it could indicate engine performance problems. Have some quick checks to figure out the culprit.

Step 1: A clogged air filter can restrict airflow to the engine, affecting its performance. So try to clean it with some dilute cleaner or replace the air filter regularly, which may cost around 10 bucks. 

Step 2: Old or contaminated fuel can lead to poor engine performance. So ensure you use fresh, high-quality fuel to prevent engine issues. It’s best to refill the fuel tank every time interval. 

Step 3: The carburetor issue is another reason behind engine performance lagging. In this case, cleaning or adjusting the carburetor might be helpful. 

First, remove the carburetor, float, and other removable components. Then soak and scrub all the components with a dilute cleaner. Rinse and dry the components; voila, they are ready to reassemble. 

Step 4: Check the ignition system, including the ignition coil and spark plug wires, to ensure they are in good condition. If needed, replace the bad parts with new ones. 

3. Transmission and Transaxle Problems

The transaxle is a critical component of the John Deere LT180 garden tractor, responsible for transferring power from the engine to the wheels. It serves both as a transmission and a differential to provide smooth and controlled movement. 

Troubles with the transmission and transaxle can result in poor performance, hydro slipping, and reduced mobility. These kinds of issues show up over time; thus, every engine has a lifetime to serve brilliantly. But luckily, this issue can be solved with some simple tricks. 

Step 1: Check the drive belt. A worn or damaged drive belt can cause slipping or jerky movements. This issue can be solved by changing the belt to a new one. This will hardly cost you 10 to 20 bucks. So why are you stuck on an old one? 

Step 2: Regularly inspect the transmission fluid levels and quality. Low-level or contaminated fluid may also impact the tractor’s performance. So if you find a problem there, you must fill it with transmission fluid. 

Step 3: Another reason for your slow tractor performance can be related to the pumps. Because of the differential, the force travels to the axle with the least resistance. For that, you should measure the clearance of the pump’s piston and bore. 

If out of tolerance,  you should spend the $365 for new pumps or trash the project and buy a newer mower.
