2. Transmission Problem

The transmission has a John Deere 6120E hooked to it. The transmission on this machine is jerky, and gear shifting is difficult, according to consumers. 

Dry linkage, low gear oil, or crankshafts in the transmission are a few possible causes of this issue.

One of the most frequent problems with the John Deere 6120E is engine overheating. Low coolant levels are the main causes. The cooling system has to be flushed. 

The thermostat or radiator cap may occasionally be broken. A faulty transmitter or water temperature indicator might potentially be the cause. 

Overheating can also be caused by a low oil level, a loose or damaged alternator belt, or both. The engine should not be used with a dirty grille, radiator screen, or radiator cooling fins. Sometimes the engine runs too quickly for the conditions, which might lead to overheating.

The Fix:

By doing routine oil changes, normal maintenance, and filter changes on time, you can keep your tractor running smoothly. Each time the tractor is used, check the filters. 

It’s crucial to clean this safety screen using a wire brush to stop any of the things on the filter from being stuck within the tractor’s radiator. In order to prevent the engine from overheating, check the filter for any buildup of dirt or other items. 

Checking the coolant levels is crucial prior to utilizing a tractor. See whether there is any debris, corrosion, or coolant debris on the cap. The best piece of advice is to avoid using a tractor on really hot days.

Exhaust smoke from your JD 6120E engine is either black or grey. Engines may also emit white smoke. And the primary causes of it are the following: the use of improper gasoline, clogged air intake systems, driving too quickly for the area, dirty or malfunctioning fuel injectors, dirty intercooler fins, and more.

White smoke is caused by low engine temperature, a defective thermostat, and a defective cold advance mechanism.
