John Deere 870 Problems And Solutions

So, what are the issues with the John Deere 870? The most typical issues include oil leaks, a jammed clutch, engine overheating, sudden stoppage, and difficulties starting. You may also encounter issues such as odd noises and engine smoke.

Overheating Of Engine

JD 870 coolant system failure causes this issue. The coolant system will fail if the coolant is low or hot. Bad radiator caps, thermostats, or temperature gauges can also cause problems.

Overworking tractors overheat. Low engine oil and improper fuel grades can also cause this issue.


  • clean Dust off the cooling package.
  • Fill the radiator with enough coolant.
  • Replace the broken radiator cap.
  • Replace faulty thermostat and temperature gauge
  • Reduce load and add engine oil

Smoke Coming From The Engine

Engine smoke is white, grey, or black. Unsuitable fuel can cause this. White smoke indicates low engine temperature. Faulty thermostats, glow plugs, and injector nozzles may cause it.

Dirty injector nozzles and air cleaners may cause grey or black smoke.


  • Replace the fuel with acceptable grade fuel.
  • Warm up the engine so that it can reach the usual temperature.
  • Clean out the dirty injector nozzles and the air filter.
  • If the thermostat, injector nozzles, and glow plug are worn out, repair or replace them.

 Engine Stalling

Tractor speed is erratic and slow when this happens. Tractors can stop unexpectedly. This happens when air, moisture, or dirt enters the fuel system.

Dirty air filters and fuel injectors can introduce pollutants into the fuel system. Low coolant temperature can also cause engine malfunction and speed inconsistencies.


  • To eliminate pollutants from the fuel system, you must bleed, flash, or drain it.
  • Remove any debris from the air filter and fuel injectors.
  • Repair or replace the faulty thermostat that controls the coolant temperature.

Tractor Doesn’t Start

Cold temperature causes this issue. The tractor may not start due to low fuel or fuel grade. Starting the engine under load may be difficult.

Air, moisture, and dust can pollute the fuel system. Dirty or faulty air filters and injector nozzles cause this. High crankcase oil viscosity prevents its functioning. Tractor won’t start.


  • Check the fuel level and replenish it to the proper amount.
  • To start in the right load, you must disconnect the PTO.
  • To remove pollutants from the fuel system, bleed, flash, or empty the system.
  • Clean the clogged air filter and injectors, and replace them if necessary.
  • Use adequate and suitable viscosity crankcase oil.

Oil Leaks

Most ancient John Deere 870 tractors have this issue. Oil leakage is usually caused by clogged or damaged tubes, o-rings, gaskets, seals, valves, and covers.

Dirt can damage these parts. Eventually, those parts may wear, tear, and crack.


  • Remove dirt specks from the valves, o-rings, gaskets, and seals.
  • Check for any damage to such components in order to fix them.
  • Inspect the oil tube or lines for cracks and repair them. If this is not possible, change the line.
