1. The Engine Struggling to Start

Almost all tractors, irrespective of the brand, will experience engine problems. Specifically, starting problems are common if the engine is not well-maintained.

But since this can happen anytime, knowing the steps to take and the things to do to remedy the problem can make using LS tractors enjoyable.

The LS engine could struggle to start if the battery has no charge or is faulty. Also, the engine will have trouble starting if the PTO switch is turned on.

Similarly, it will not start if the fuel filters are clogged and do not allow fuel to reach the engine.


  • Check the battery to see if the circuit is complete, and tighten the terminals if possible.
  • Check if the PTO switch is turned off.
  • Check the starter solenoid.
  • If the starter solenoid has failed, consider replacing it.
  • If the fuel filter is old and clogged and does not allow fuel to reach the engine, consider cleaning or changing it.


2. Engine Stalling While in Use

The engine may start but stall after some time. In some cases, it may stall mid-use. This is frustrating and could waste your time.

Stalling may happen if there is a fuel issue. Besides, a clogged fuel filter that blocks fuel from reaching the engine could also cause the problem.

Stalling could also occur if the nozzles that vaporize fuel in the combustion engine have issues and are underperforming.

A problematic nozzle does not vaporize or allow enough oil to flow to the combustion chamber. As a result, it becomes difficult for the chamber to maintain the combustion process.


  • Check the tank and ensure there is enough fuel to avoid starving the engine.
  • Replace the fuel filter.
  • Clean or change the nozzle to enable it to vaporize enough oil in the combustion chamber.
  • Check and fix any issues with engine lubrication points if they are causing inefficiency.
  • If the engine shuts at low speed only, the cause is a faulty injection pump or incorrect valve gap. Therefore inspect and repair them.

3. The Engine Overheats

The engine overheats when the tractor cannot dissipate the heat it generates. This could happen if there is a problem with the coolant or the radiator.

If the coolant is insufficient, the engine may overheat. Similarly, if the radiator screen is dirty and blocked, it leads to more problems.

Lastly, if the air filter is clogged, it may not allow clean air to circulate in the engine. So the engine retains the heat it generates, leading to overheating.


  • Top up the coolant during regular maintenance.
  • Check the radiator screen and ensure it allows heat to dissipate. Unblock it by washing it to remove dirt.
  • Wash and replace air filters accordingly.

4. The Engine Produces Smoke

When smoke starts coming from the engine, you will likely get alarmed and panic. However, this is not a severe problem, so it may be vital to remain calm.

But the presence of smoke is a sign of burning excess oil. This happens when there is a problem. Hence the sooner you take care of the problem, the better for your tractor.

One of the leading causes of the problem is a clogged air filter which creates a heavy fuel mixture that does not contain enough air.

It results in incomplete combustion. Also, if oil leaks onto the muffler, it gets burnt off and releases smoke. The presence of oil on the muffler is a sign of a leaking fuel system.

Similarly, if the machine has been in store for an extended period, burning old and stale oil could make the engine produce smoke.

However, if the engine produces white smoke that irritates the eyes, it means that it is burning the oil. Such smoke could irritate the eyes or the skin.

Thus finding a solution to the problem may protect the tractor from further deterioration.


  • Check, clean, or replace air filters.
  • Check the fuel systems for leaks and find an appropriate remedy.
  • If the oil is old, replace it.
  • Check the fuel injectors in case of white smoke and consider replacing them.

5. The Engine Does Not Have Enough Power

If the engine starts well but struggles to keep the tractor moving, it could be a mechanical issue or fuel problem.


  • Check the fuel tank level and refill if it is too low.
  • Check and unblock the injection nozzles. If they are faulty, ensure to replace them.
  • Check the oil filter and ensure it allows the oil to flow.
  • If there is leakage or the fuel line is compromised, check and repair them.
  • If the fuel pump is not delivering fuel correctly, replace it.

6. Steering Problem

Steering problems are dangerous. They make turning the tractor in the right direction hard and could result in a serious accident if the tractor carries a heavy load.

Your tractor will experience a steering problem if the hydraulic is not delivering sufficient pressure to steer the tractor in the desired direction.

Also, misaligning the column spline and the steering unit could cause a problem.

When the air gets into the hydraulic system, it reduces efficiency, making it hard to steer the tractor in the right direction.


  • Check and realign the column spine and the steering unit. If they are disconnected, reconnect them.
  • Ensure the pump is working and that there is sufficient hydraulic oil. Also, check and ensure that no air gets into the hydraulic system.
  • Raise the temperature of the fluid to get the air out of the hydraulic system.

7. Electrical Problem

Electrical issues are expected not just in LS tractors but almost all automobiles.

They may originate from the battery itself, the terminus, or the circuit. If the battery sits idle for a long time, it discharges and may need a recharge before it can start the tractor.

If the cables are nipped, causing circuitry discontinuity, no power reaches the starter. Similarly, if the terminals are dirty and rusty, the power may not get to different parts of the tractor.


  • If the battery has been idle for a long time, recharge it. If the tractor sits idle, ensure to start and run it every couple of days.
  • Inspect the cables to ensure continuity and replace those that are worn out.
  • Inspect and clean the battery terminals often to prevent a build-up.
  • Visit a local dealer if the problem is persistent.

Faulty Filters and Brakes

Filters block fuel debris from getting into the engine. But when the filters are faulty, they may allow the debris to get into the tractor engine and could result in serious problems.

Similarly, the bakes will enable you to regulate the tractor’s speed or stop it when in motion. When they fail, driving the tractor may be a problem.

  • Check and replace the filters according to the LS tractor manufacturer manual.
  • Ensure the brake fluid level is ok.
  • Repair brakes after some time.
