See below for the response I received from John Deere.
Thank you for contacting John Deere in regards to your 2013 2025R Lawn Tractor.
Based on the information you have provided, Backhoe Model numbers 270A and 46 are the models you are searching for. However, we recommend that you verify compatibility with your local John Deere dealer. Your dealer will be able to advise you on which Model is best for your situation and advise you on anything else your unit may need.
Sure. Here's specs on both too. 46 specs and 270A. After looking things over I think I'd go with the 46. It's harder to install/remove, but has more lift capacity, more swing, boom digging force, etc. I almost bought a 270A when I got my 2320, but decided against it.
