Yes, it's the same. The 2032 just a rebadged 2720, they changed the model numbly to comply with the new numbering scheme JD went to.
For the grapple you mentioned, be sure to check out the new offering from Artillian as well, and of course the fork sets, nothing would fit your machine better. There are a few threads with pics over on the GTT forum.
I already have pallet forks so Artillian's modular system, while cool, doesn't make sense for me. Their third-function kit looks like it's put-together perfectly though! I've got to get through some home renovations before I have time to mess with modifying the tractor. What's the approximate install time for a kit like that?
For the Artillian 3rd function kit, what does the "aux power plug" entail. Does it have a pigtail that plugs in somewhere inline in the wiring harness of the tractor, sort of like plug-and-play trailer light kits for cars? Or is it just a cigarette lighter plug that you actually physically plug into the aux power on the tractor?
