With a 60 hp engine and lift capacity of 4800 pounds, it packs impressive power into a small footprint. However, like any machine, the LS180 can develop issues over time.

In this guide, we’ll overview the most common New Holland LS180 problems and detail troubleshooting tips to get your skid steer functioning properly again.

Main Causes of New Holland LS180 Problems

Before diving into specific issues, it helps to understand the main sources of problems on the LS180. This can give you a head start on diagnosing issues when they arise. Here are the top culprits behind New Holland LS180 failures:

  • Hydraulic system problems – Hydraulic fluid leaks, contamination, faulty valves, and other hydraulic problems are a common source of malfunctions. Issues here can affect lift/tilt functions.
  • Engine problems – With hundreds of moving parts, diesel engines are prone to wear and tear over time. Fuel, air, and electrical issues can lead to starting, stalling, smoking, or power loss.
  • Drive system problems – The chain, motor, and hydraulic pumps of the drive system have many failure points. Wear and tear here leads to loss of drive power.
  • Electrical issues – Corrosion, faulty starters, and dead batteries are common electrical gremlins. These can cause no starts or other electrical failures.

Keeping these problem sources in mind, let’s get into the specific LS180 issues and fixes.

1. LS180 Won’t Start

Difficulty starting is one of the most common frustrations with the New Holland LS180. There are a few key items to check if your skid steer won’t fire up:

  • Battery – Weak or dead batteries are a universal cause of no-start situations. Try jump starting the LS180 or charging/replacing the battery if cranking is slow.
  • Electrical connections – Corroded battery cables or loose wiring can disrupt power flow. Check for green crusty buildup and tighten connections.
  • Filters – Clogged air and fuel filters starve the engine of vital ingredients to run. Replace filters if restricted.
  • Fuse – Check for blown fuses in the starter circuit. Replace any that are fried.
  • Start relay – The start relay sends power to the starter when the key is turned. Replace this relay if faulty.
  • Starter – Starters do eventually wear out. If all else checks out, starter replacement may be needed.

Also ensure you are following proper starting protocol if the machine cranks but won’t start:

  • Wait for glow plug light to turn off before cranking
  • Don’t crank for more than 30 seconds at once
  • Allow starter to cool between cranking attempts

2. Loss of Drive Power

The hydrostatic pump and drive motors provide pushing power to the LS180. But worn components or hydraulic issues can lead to lackluster performance. Try these troubleshooting tips for weak drive power:

  • Low hydraulic fluid – Insufficient fluid flow starves the drive system. Check level and top up as needed.
  • Contaminated fluid – Dirty hydraulic oil lacks lubrication. Drain fluid and replace filters.
  • Worn drive chain – Chain stretch reduces drive efficiency. Inspect chain wear and replace at 2-3% elongation.
  • Hydrostatic pump – Worn pumps and motors eventually require rebuild or replacement.
  • Drive belt – Loose or worn drive belts to pump rob power. Adjust or replace belt.

Also, go easy on cold systems – wait for machines to fully warm up before heavy loading.

3. Jerky or Slow Lift/Tilt Movement

Proper hydraulic pressures and flow rates are needed for smooth boom and bucket control. If lift or tilt response feels rough or sluggish, try these tips:

  • Low hydraulic fluid level – Top up reservoir if low. Bleed air from lines once refilled.
  • Blocked suction strainer – Clean strainer screen/filter to improve intake flow.
  • Faulty hydraulic valve – Spool valves control fluid flow to cylinders. Replace if worn.
  • Damaged hydraulic pump – Worn vanes lead to pump replacement. Listen for grinding.
  • Cylinder leakage – Rod seal failure causes air pockets in the cylinders. Rebuild or replace leaking cylinder(s).
  • Hydraulic restrictions – Kinked hoses or clogged filters restrict flow. Inspect/replace as needed.

Slow, uneven movement is a telltale sign of hydraulic problems. Address these promptly before total failures occur.

4. Overheating Issues

Excessive heat is damaging to any engine or hydraulic system. Overheating on the New Holland LS180 usually stems from these causes:

Engine overheating

  • Low coolant or radiator fan failure – Maintain proper coolant level. Check/replace radiator fan.
  • Loose/broken fan belt – Inspect belt condition and adjust tension.
  • Clogged radiator – Clean debris from radiator fins.
  • Stuck thermostat – Replace faulty thermostat that won’t open.
  • Coolant leaks – Address any external leaks detected.

Hydraulic overheating

  • Low fluid level – Fill reservoir to proper level.
  • Blocked intake strainer – Clean strainer screen for unrestricted flow.
  • Wrong hydraulic fluid – Use manufacturer-approved fluid.
  • Excessive workload – Reduce machine workload cycles.

Monitor temperatures closely to avoid overheat damage. Shut machines down if limits are exceeded.

5. Excessive Engine Smoke

Seeing plumes of smoke from your New Holland is always concerning. Blue, black, or white smoke generally indicate:

  • Blue smoke – Oil burning. signs of failed engine seals, turbo issues, or hydraulic leaks.
  • Black smoke – Rich fuel mixture. Clogged air filters or faulty injectors may be the culprit.
  • White smoke – Coolant burning. Head gasket or other engine leaks allow coolant to mix with combustion.

Reduce operating load on smoking machines and determine root cause. Repair oil leaks, replace air and fuel filters, adjust injectors, or rebuild engine as needed. Don’t operate with chronic smoking issues.

6. Fuel or Hydraulic Leaks

Fluid leaks create immediate safety and performance concerns, as well as lead to eventual component failure down the road. Be vigilant for leaks and address them promptly.

Fuel leaks – Look for diesel stains around injectors, filters, lines, and tanks. Replace affected components.

Hydraulic leaks – Inspect hoses, fittings, cylinders, valves, pumps, and seals. Tighten fittings or replace leaking parts.

Clean up spilt fuels/oils immediately to reduce risk. Take precautions against fires when leaks are detected.

7. Turbos or Injectors Need Replacement

Though expensive replacements, faulty turboschargers and injectors are common repairs on high-hour LS180s.

Turbo failure – Look for blue smoke, sluggish power, and oil around compressor. Replace turbo if wheel shaft is loose or bearings are shot.

Injector issues – Symptoms are hard starts, misfires, black smoke, and performance codes. Remove and have injectors cleaned or replaced as needed.

Shop around for turbo/injector parts – significant cost savings over dealer prices are often available.

8. Electrical Gremlins

Like most equipment, the New Holland LS180 has its share of electrical woes that can arise. Be prepared to tackle issues like:
