Well Googling “John Deere 425 PTO Switch” didn’t do me any good other than waste $20. IMG_5159.jpg
Looks pretty close here right?

Well it’s a different pin configuration. IMG_5158.jpg
Note the bottom of my old switch has two NOT close together. The new switch has two close together.

So I guess this isn’t the right switch for my Early 425? I wish there was a part supplier that I can actually use my serial number to see if I’m buying the right part number. Or even find a parts blue up where I can actually find the part I need. Where the F**K is the pto switch in any diagram? Any help would be appreciated

Bottom of old switch for your reference to help identify it vs the one I bought

Hi Undercover. In June of 2016 I replaced the pto switch on my 925m ztr. The geometry of the pins is the same as your old switch. The part# from my Deere dealer was TCA21027. I’m sure because I kept the old switch as a spare since replacement did not fix my issue back then .

Good luck.

It's NOT same switch for above and below serial number 70,000

LVA21437 & A-B1EM48 is for 70,000 and below.

AM21438 is for 70,001 and above.
