Well I got started on this yesterday when we were discussing that my top pin in my backhoe would not come out because of the top 3 point hitch arms. After getting a few replies, I think my mast may be mounted wrong. Unfortunately, in my 4690 book, there is no page for the 2910, (or the 2710). I think the Backhoe book is old, so I've called Kubota, and I'm waiting for a return call. In the meantime, I measured the clearance from my backhoe seat to the ROPS and is only 30". Even with the seat pushed all the way forward, it will probably be only 32". Do I have the wrong ROPS, or is my Backhoe just mounted way too high. There is no number on my ROPS, but when I measure it, it goes exactly 34" from tractor base to the bottom of the ROPS. Attached is a photo of by beautiful "Yoda" Kubota. You may or may not can tell anything from the photo of the hoe. Thanks for any help on this. I don't think my dealer has sold many hoes.....
