What to do if the 3-point linkage does not move down when control handle is moved to down position on New Holland Tractor?
- V
  Veronica DavisSep 14, 2025
  If the 3-point linkage does not move down when the control handle is moved to the down position on your New Holland Tractor, it could be due to the down speed control valve locked in the closed position (turn the knob counterclockwise to open the valve), control valve failure (repair or replace valve), a damaged hydraulic lift cylinder (repair cylinder as needed), or damaged lift shaft moving parts (repair or replace lift shaft parts as needed).

Why is the instrument panel battery charging indicator "ON" during operation on my New Holland Tractor?
- S
  Susan LeeAug 25, 2025
  The instrument panel battery charging indicator might be on during operation of your New Holland Tractor due to a bad electrical connection. Check the battery terminals and ground, and repair as needed. It could also be due to a faulty alternator (repair or replace as needed), a faulty battery (replace the battery), or incorrect fan belt tension or a broken belt (adjust belt tension or replace the belt).

What to do if the start motor does not rotate with the key switch in the (START) position on New Holland Tractor?
- Y
  youngsusanAug 26, 2025
  If the start motor does not rotate when the key switch is in the (START) position on your New Holland Tractor, it could be due to several reasons. The battery charge might be low, so charge or replace it. The battery or starter cable terminals could be loose, so tighten them. The key switch might be faulty, requiring repair or replacement. The safety start switch might not be completing the circuit, so depress the clutch pedal fully. Ensure the PTO safety switch is in the "OFF" position. Finally, the starter motor itself might be faulty, needing repair or replacement.

  Low HST power can be attributed to oil shortage (add transmission oil as needed), air in HST circuit (check and repair the hydraulic suction line), transmission oil temperature being too high (shut down tractor to cool the transmission oil, and restart after oil temperature has been reduced), HST internal parts worn (repair HST transmission as needed), or a clogged HST filter (replace the HST filter).
