Hi everyone, I think the starter in the 425 is going out, do I have to pull the engine to replace it? How can a person check the starter to see if it is the starter? Now it is mowing season so it figures something like this would happen! Ok I will sit back and wait for replys!!!!

Maybe a better description of what the problem seems to be with the starter.. not much to go on so far.

Well when you turn the key to start the solenoid on the starter seems to not engage and then it does? Now after it has warmed upped the starter engages like it should. I saw a little smoke coming off the end of the solenoid on the starter today. I hope this helps!

Ok I will ask this....Has anybody changed a starter out in a 425 garden tractor? If so how did you do it? Thanks Weeder!!!!

That smoke could be coming from a poor connection, I think there are fusible links down on the starter solenoid that provide power for the rest of the tractor.

I'll ask.. have you tried to remove it?

Before I replied, I went to the shed and popped the hood.. took a few pics.
Looks to me that removal would not require removing the engine from the tractor. Two bolts shown with red arrow.
May need to remove a few things to get at the starter, but that routine just becomes part of it.

I have checked all of those and they are in good shape

Well there's the problem. Everybody knows that electrical stuff operates on smoke. When the smoke leaks out, it stops working.

I have had the starter off my 425 many times. Don't enjoy the job but I found if you remove the coil it's easier to get to the bolts. Since this is a Japanese engine they are probably metric I used a box end wrench and you only can move it a fraction of a turn. It takes some to get the bolts (2) out. It takes a little twisting to get the starter out of the housing. I took my starter to repair shop and he checked it out and cleaned it. So after all the time it takes to remove and install the starter still acted the same. removed it again and took it back and he put a new bendex drive in it which he should have in the first place. It now works fine.

Most of the time the starter is fine and the problem lies in the control and ground circuits.

If you do not diagnose this properly you will have a new starter with the exact same problem.

You need two cheap tools to do some simple diagnostic steps.

A multi meter for less than $10

A test light again for less than $10

The issue of smoke makes me think there is a dirty connection on the battery ground cable, .

A multimeter test when the engine is cranking will tell a lot.

John Deere has been selling kits to provide a stronger signal to the starter solenoid when safety switches start to become corroded.

You can easily make your own.

Get the meter and test light and come back for more instructions

In the list showing in your link, the JD 425 isn't on that list.. leaves one to wonder if the relay kit is not for the 425.
