SG-JD14-CT8 - Machine Side John Deere 14 Pin to Attachment Side Cat, Terex & ASV 8 Pin | Skid Steer Genius

  • $285.00

Ask a Question

Here's a Genius idea.  Why not allow people with Caterpillar attachments run them on their John Deere Skid Steer Loader?  This adapter does just that.  Just plug one end into your John Deere Loader and plug the other into your attachment equipped with an 8 pin connector.  Turn on your machine and get to work.  This is another Genius product.  The best ideas at the best prices.


Note:  John Deere 14 Pin outputs 6 switched ports.  Caterpillar/ASV/Terex only outputs 4 ports.  You will notice that this adapter has 5 pins installed.  Up/Down & Left/Right are all that is available.  This is a manufacturer limitation and not something that we have introduced.

  • i have a john deere 326 e with a 14 pin plug with only 7 pins .i want to run a cat hm418c mulcher will the SG-JD14-CT8 WORK? THANK YOU.

    If the mulcher is an old 8 pin and olny has 3 hydrauic lines, then yes.

  • We have a customer with a CAT PC310B Planer, on serial number tag says built in 2016, that we need to attach to a newer John Deere 333G. Would adapter SG-JD14-CT8 be the correct for this situation?

    You are right in a transitional year.  The older units had an 8 pin connector and 5 hydraulic lines.  These will not work as is on a modern 14 pin machine.  The cost to convert wil cost about $4000.  The modern 14 pin attachments can be converted to use with this adapter.



    Do you mean in Reverse?  If so, the part number is SG-CT8-JD14. Here is the link.

  • I have a customer with a Cat planer that has this connector but it has 7 pins in it. I want to hook it to a Deere skid loader (14 pin). Will this still work?

    There are two types of connections on Cat attachments.  8 Pin which are installed in Cat A,B,C series and 14 pin which are for Current D series models.  Older 8 pin planers have 5 hydraulic lines.  These will not work on your JD.  Newer D series planers have 3 hydraulic lines and will work on your JD. 

    You need to verify exactly what you have an choose this adapter if it is a D series.

  • I have a Kubota snowblower (SBL 2574) that I want to connect to a John Deere 333G. Will this adapter work for this application?

    No it will not.  You need a John Deere to Kubota adapter which is the same as a Bobcat.  SG-JD14-BC14.

  • I am trying to sell my JD 332G to a guy with a Volvo CTL, he has a cold planer and broom, do you make an adapter for the JD machine to Volvo attachment?

    Certainly - CLICK HERE

  • need a plug to go on erskine grapple to a 2012 cat 262 ? and will that fir a newer cat 299?

    What kind of plug is on the grapple?  What series is your machine?  A,B & C series use 8 pin Deutsch while D series use a 14 pin Deutsch.

  • Erskine 2410XL ser# 1028417 snowblower uses 6 pins of the 8 pin connector. Attaching to a 2021 Deere 324G hiflow eh control 14 pin. The sg-jd14-ct8 seems right but I will need blower motor on/off, spout rotation and deflector cylinder. The blower has 3 lines. Can I have all 3 functions with this adapter

    The blower runs with the hydraulics.  Only the chute controls use electrical.

    Erskine usually uses a trailer plug which is 7 pins.  Can you send a photo of what you have please?

  • I have a cat 8 pin dozer blade trying to get an adapter for a deere 14 pin

    This is the correct adapter.

  • Can this machine deer skid to cat attachment jump work the opposite way? I have a cat skid and a Deere Harley rake. Got rid of my Deere skid and need a jump for the new skid

    This is exactly backwards to what you are asking.  You have a CAT machine so the part number would be SG-CT8 or 14.  You have a JD attachment but the attachment usually comes with a 3 pin and not a 14 pin so we cannot guess for you.  How about you send us a photo of the machine connector and the attachment connector and we will send you a link to order?

  • Will this work for a 333g high flow on a cat high flow snowblower

    If the Cat snow blower has an 8 pin connector.

  • I have a 2019 JD 333G, I am wanting to hook it up to a new 2022 FAE Rock Crusher. Will this harness work?

    If the FAE is wired for a Cat 8 pin, then yes.
