I think the grapple worked great once I finally found fittings to use it. My John Deere loader has the small 1/4" small female quick couplers for both lines and it would not work of course with the 1/2 male and female on the attachment. I was not able to get answers or adapters from Deere dealer so after multiple days of searching i found and figured out adapter fittings to connect hydraulics to use it. It appears that there is not an adapter that i could find internet included for this issue. The attachment works now but i will need to figure out something different because connection is not quite rite but will function for now. The Grappel is great tool but i think looking into adapters for them to aleviate this issue would be great. It was very frustrating from my view especially since nothing on line or Deere dealer didn't have any answers. I have a 4066R with a 440R loader if that will help anything. If you have any ideas or fixes i would definetly appreciate your opinion. Thank you my Order was #11100343540.
