⚠️ Common New Holland Workmaster 50 Problems & Fixes

1. Hard Starting in Cold Weather

Problem: Owners report difficulty starting the engine in colder temperatures, especially below 20°F (-6°C).

Fixes:

  • Use a block heater to preheat the engine.
  • Replace glow plugs if weak.
  • Use winter-grade diesel fuel.
  • Check battery voltage (should be 12.4V+).

Tip: Let the glow plugs warm for 10+ seconds before cranking.

2. Hydraulic System Problems

Problem: Slow or unresponsive 3-point hitch, loader movement, or jerky hydraulics.

Causes:

  • Low hydraulic fluid
  • Dirty hydraulic filters
  • Air in the lines

Fixes:

  • Top off hydraulic fluid to recommended level.
  • Replace filters regularly (every 300 hrs or sooner).
  • Bleed air from the hydraulic system.

3. PTO Won’t Engage or Disengage

Problem: The Power Take-Off (PTO) either stays engaged or refuses to turn on.

Common Causes:

  • Faulty PTO switch or linkage
  • Electrical issue (HST model)
  • Hydraulic pressure loss (gear model)

Fixes:

  • Check and clean PTO switch contacts.
  • Inspect linkage for rust or bends.
  • Reset hydraulic valves (or replace if worn).

4. Overheating During Heavy Use

Problem: Engine temperature spikes while mowing or using implements.

Causes:

  • Dirty radiator fins
  • Coolant level low
  • Thermostat failure

Fixes:

  • Clean the radiator and oil cooler fins with air pressure.
  • Flush and refill the cooling system.
  • Replace thermostat if stuck closed.

5. Clutch Slipping or Sticking

Problem: Gear model tractors may experience clutch issues, particularly under load or when shifting between gears.

Fixes:

  • Adjust clutch pedal free-play.
  • Check clutch for wear or oil contamination.
  • Replace clutch if slipping continues.

6. Electrical Faults

Problem: Dashboard lights flicker or key switch intermittently fails.

Fixes:

  • Clean ground wire connections.
  • Replace corroded battery terminals.
  • Use dielectric grease on fuse connectors.

7. Fuel System Airlocks

Problem: After fuel filter replacement or low fuel run, engine stalls or fails to start.

Fixes:

  • Open bleeder screws on the fuel lines and manually prime.
  • Replace fuel filter and ensure correct seating.
  • Tighten all fittings.

8. Steering Stiffness or Fluid Leaks

Problem: Power steering becomes difficult or leaks appear under the front axle.

Fixes:

  • Check steering fluid level.
  • Inspect seals and steering cylinder for leaks.
  • Replace worn hoses or tighten fittings.

9. Transmission Gear Grinding (Gear Model)

Problem: Grinding noise when shifting into gear or reverse.

Causes:

  • Incorrect clutch adjustment
  • Operator error (not pausing between shifts)

Fixes:

  • Re-adjust clutch linkage.
  • Pause 2–3 seconds before shifting between gears.

10. Loader Arms Drop Slowly When Idle

Problem: Loader arms sink slightly when parked, even without use.

Likely Cause: Internal leak in hydraulic cylinders or control valve.

Fix: Rebuild loader cylinder seals or replace faulty spool valve.

🧰 Maintenance Tips for Longevity

  • Change oil every 100 hours or annually.
  • Replace fuel and air filters every 200–300 hours.
  • Check hydraulic fluid and top up as needed.
  • Grease all fittings every 10 hours of loader work.
