John Deere 280-324 Series & B350 Common Problems This Manual Covers
John Deere 300 tractor won't start, starter clicks but engine cranks slowly or not at all
Test battery voltage at the positive terminal first; anything below 11.8 DC volts, charge or replace the 95D31L 12V 85Ah battery. Clean and tighten both ground cable connections at the frame. If the battery checks good, verify battery voltage reaches the starter solenoid terminal using the starting system tests on page 676.
Manual Section: Electrical System Diagnosis, Test and Adjustment p. 676Engine overheats under load, coolant boils over after an hour of heavy fieldwork
Check fan belt tension first: press at the middle of the belt with 29 to 39 N of force; deflection should measure 10 to 15 mm, per the check on page 621. Blow plugged radiator fins clear with compressed air, then verify the system holds its full 8 L (2.11 gal.) coolant charge.
Manual Section: Engine Diagnosis, Test and Adjustment p. 621Clutch slips under load, tractor loses forward drive when pulling implements uphill
Work through the clutch slippage procedure starting on page 773. Inspect the friction disc for glazing and oil contamination from a leaking rear main or input shaft seal, and adjust clutch pedal free play to spec. Check gearbox oil level too; overfilling past the 15 to 16 L capacity forces oil past seals.
Manual Section: Drive System Diagnosis, Test and Adjustment p. 773Three-point hitch lifts slowly or won't raise a loaded implement at full throttle
Check hydraulic oil level and condition first; the lifter circuit holds 7 to 8 L. Replace the lifter filter element if it has more than 500 operating hours on it, per page 482. Then run the slow-lift diagnosis starting on page 826, and torque any weeping M12x1.5 steel connectors to 21 N·m.
Manual Section: Hydraulic System Diagnosis, Test and Adjustment p. 826Engine runs rough and loses power, black exhaust smoke pours out under heavy load
Clean or replace the air filter element; it needs service every 50 hours, sooner in dusty conditions, per page 81. Inspect the fuel tank cap vent for clogging, drain stale fuel from the 40 L tank, refill with fresh diesel, then bleed air from the fuel system before restarting.
Manual Section: Fuel System, Air Intake and Exhaust p. 81Frequently Asked Questions
