If the fuel injection system is clogged or malfunctioning, it can prevent the engine from receiving fuel properly. The fuel injectors could be dirty or blocked, which would restrict fuel flow to the engine. A professional cleaning of the injectors may be necessary.
If the engine has poor compression, it may struggle to start. This can be caused by worn piston rings, valve problems, or cylinder issues. A compression test can determine the health of the engine’s internal components.
In rare cases, the electrical system could be the source of the issue. Faulty wiring, bad ground connections, or a malfunctioning electronic control unit (ECU) could prevent the engine from starting.
A non-starting New Holland LX865 skid steer can be caused by a variety of issues, ranging from simple problems like a dead battery to more complex mechanical or electrical failures. By systematically addressing potential causes, you can identify and resolve the issue more efficiently.
If the problem persists despite your best efforts, it’s advisable to consult with a professional mechanic who can diagnose the issue with specialized tools and expertise. Regular maintenance, including checking the battery, fuel system, and filters, can help prevent future starting issues and ensure that your equipment continues to perform at its best.

1. Battery Health
The most common issue in machinery that won’t start is often the battery. Over time, batteries degrade, lose charge, or suffer from terminal corrosion, which can prevent the vehicle from starting. Start by checking the battery:
- Battery Voltage: Use a multimeter to check the voltage. A healthy battery typically has a voltage between 12.6V and 13.0V when fully charged. If the voltage is below this, it may indicate that the battery is dead or failing.
- Corrosion: Check the battery terminals for corrosion, which can impede electrical flow. Clean the terminals using a wire brush and a mixture of baking soda and water if corrosion is present.
- Connections: Ensure that the battery cables are securely connected. Loose or broken cables are a common reason for starting issues.
Next, check if the skid steer has an adequate fuel supply. Fuel system issues can also prevent the engine from starting or cause it to stall after a short run.
- Fuel Level: Make sure the fuel tank is not empty. It may seem basic, but this is an easy thing to overlook.
- Fuel Quality: If the fuel is old or contaminated, it can cause starting issues. Consider draining the fuel and refilling with fresh, clean diesel.
- Fuel Filter: A clogged fuel filter can restrict fuel flow to the engine. Inspect and replace the fuel filter if needed.
Blown fuses or faulty relays can disrupt power to critical components like the starter motor, fuel system, or ignition. Check the fuse panel for any blown fuses and replace them as necessary. Also, inspect any relevant relays related to the starting system.
Common Mechanical Problems and Solutions
If the basic checks don’t resolve the issue, it’s time to move into more specific mechanical troubleshooting. Several common mechanical issues could cause a New Holland LX865 to fail to start.
1. Starter Motor Issues
A faulty starter motor is a common culprit in non-starting situations. When you attempt to start the skid steer, listen for a clicking noise, which can indicate that the starter motor is receiving power but failing to engage properly.
- Starter Motor Condition: A worn-out starter motor may fail to engage the flywheel. Check for physical damage or signs of wear.
- Solenoid: The solenoid is part of the starter system and can fail, preventing the starter motor from turning over the engine. If the solenoid is not working, it will need to be replaced.
The ignition system is responsible for generating the spark necessary to start the engine. If the ignition system is malfunctioning, it may prevent the engine from starting. Key components to inspect include:
- Ignition Switch: The ignition switch could be faulty. If it’s not making proper contact or is worn out, it can fail to send the necessary signals to the starter motor.
- Spark Plug: A damaged or worn-out spark plug can also prevent engine ignition. Check the condition of the spark plug and replace it if necessary.
- Wiring Issues: Inspect the wiring that connects the ignition switch to the starter and fuel system. Loose or corroded wires can cause intermittent starting problems.
In some cases, hydraulic system issues can contribute to a non-starting situation. For instance, if the hydraulics are “locked” due to excessive pressure, it can prevent the engine from turning over.
- Pressure Relief Valve: Check the pressure relief valve in the hydraulic system. If it's stuck or malfunctioning, it can cause excessive pressure buildup.
- Hydraulic Hoses and Connections: Inspect all hydraulic hoses and connections for leaks, as leaks can lead to loss of hydraulic fluid and affect system performance.
Clogged air filters or blocked exhaust systems can prevent the engine from receiving sufficient air or expelling exhaust gases, which are necessary for starting.
- Air Filter: A clogged air filter can suffocate the engine, preventing it from starting. Replace the air filter if it appears dirty or clogged.
- Exhaust Blockages: Ensure there are no obstructions in the exhaust system, such as soot or debris, which could block airflow and prevent the engine from starting properly.
If the problem persists after completing the above checks, you may need to perform more in-depth diagnostics or consider component replacements.
