About John Deere Company
John Deere is a leader in agricultural equipment. In addition to reliability and durability, it also means meticulous machine care. Because the machine is subjected to constant high stress and clogging, you need to have it inspected on time.
Do-it-yourself inspections aren’t recommended. Since most John Deere users lack the necessary skills and equipment, there’s a risk of damaging parts during an independent repair. It's much cheaper and quicker to call a service center. In addition, each authorized service center has a PowerGard program that extends the warranty service. You need to sign a contract with an authorized service center of the company and it will take care of the service of your equipment.
Why does John Deere starter break down?
Special equipment is constantly exposed to moisture, dust, and various debris, which in turn negatively affects the mechanism. Therefore, the starter, as well as other parts of the engine are made airtight. But contamination is not the only cause of failure. Parts tend to wear out, as well as the wiring.
Let's look at the most common John Deere starter problems:
-
The starter cranks slowly. This may indicate a low battery charge, oxidized contacts, or oil that is too viscous.
-
If the armature turns but the shaft remains stationary, this indicates a worn clutch.
-
The starter runs longer than necessary - a problem with the wiring.
-
A loud noise. Several possible causes: worn bearing bushing, flywheel, or pinion.
-
The starter does not work at all. This indicates a faulty relay, winding, contact failure, or just a dead battery.
The John Deere starter, unlike the same alternator, is simpler. If you have the necessary knowledge and tools, you can fix it yourself, but it is recommended to contact the service center. If the starter is constantly breaking down, replacement of individual spare parts will not solve the problem, you need to change the entire starter.

How to replace John Deere starter in a lawnmower?
-
The first thing to do is to disconnect the battery power: disconnect the terminal of the negative cable, then the positive cable (they are marked black and red respectively).
-
In a lawnmower, the starter motor is on the bottom of the engine. But given that engines change all the time, orient yourself to the new starter determining its future location.
-
Disconnect all cables from the starter with a wrench: the positive cable on the back and the ground cable. The wiring harness can be removed by pushing on the locking tab.
-
Unscrew the mounting bolts and pull out the starter (keep the original bolts). If there are gaskets left over from the old starter for a tighter fit to the engine, leave them behind.
-
Position the new john deere starter so that it fits snugly against the blocks and so that the starter pinion works with the pinion inside the engine.
-
Secure the starter.
-
Connect the cables and harnesses.
-
Connect to battery power.
-
Check the operation of the new starter.
Replacing John Deere starter

Disconnect the terminals from the battery, first the negative, then the positive.
-
The john deere starter is located on the left side of the tractor. Locate it and unscrew the terminals that are attached to it.
-
To remove the starter, unscrew the two bolts that hold it in place.
-
The fuel filters will interfere with getting the starter out, so unscrew the mounting bolt and remove them, but do it carefully as there is still fuel inside.
-
After putting the new starter in place, bolt it down.
-
Put the fuel filters back in place, secure them.
-
Connect the wiring to the starter.
-
Secure the wire terminals to the battery.
-
Test the operation of the new john deere starter.
