I just logged in to the JD website (I registered a few months ago; it's free) and they don't even list any parts for that backhoe, nor for my backhoe. They do have parts for my loader, sickle mower, tractor, etc. I'm guessing that they just haven't gotten the backhoe parts up on their website yet.
The file may exist on the Web, however. Hmmm... I wonder if this 3MB file would be of any use to you....

I just went to JD parts and found both the 48 and 448 hoes, did you just put "48" in the model search box?

wow!
did you search around that site, (imdl.gatech.edu/jfrankel) and read about the research they are doing with hydraulic equipment?
they're making a "haptic" backhoe.???!!!!

On the 48 back hoe subject any of you have the sub frame, when I got mine no one mentioned it now I hear JD strongly recommends it, does it come standard with the 448?
I've hardly used my BH but I've heard of rental units getting messed up from not having the subframe (tractors breaking in half?), dealer told me the trick is to keep the rear tires on the ground when digging not raised way up in the air with the stabilizers.

Thanks, Dutch445. I hadn't looked at the rest of that web site. For others reading this, a "haptic backhoe" is one where the hoe is controlled by a computer which is responding to a user's movement of joysticks but with the added feature that the computer provides feedback to the joysticks so that the user can feel resistance to motion.
I've used a haptic tool which simulated placing sutures (stitches). The tool was the needle, and you could feel (and see on the screen) the needle pushing against the skin, then feel it puncturing the skin, and feel the pull of the suture as you pulled it through the skin, etc.

I'd recommend the subframe too. Keeping the rear tires on the ground might help, but I don't think it's as simple as that.
When the hoe is forced down, the stabilizers and/or rear tires will act as a fulcrum (balancing point) and the front part of the tractor will be under a downward force. That force is transmitted to the front wheels by the tractor's "frame" which is usually the transmission housing and engine. Over time, repeated stresses can cause the tractor to "break in half".
A subframe goes all the way up to the front wheels, thus carrying the stress which would normally be applied to the transmission/engine.
