I was just at my JD dealer asking about what was reqd to mount a 448
on a 4720 tractor. I saw the "bracket", which mounts to the rear axle
casting and prob weighs 100 lb or so. It is not like most other subframes
in that there are no rails to transfer moment forces to the forward part of
the tractor. I did not have my Nikon with me at the time, unfortunately.

It's not a sub frame. The 448 can be used with a midmount mower. The older series that the 3000 replace can mount a 448 but need a subframe. The 448 mounts better than any other brand out there. I seriously considered the woods because of the thumb but after seeing how the 448 mounted and became part of the tractor it was a no brainer. Look at the other guys tractor with backhoes they all stick way out and look out of place the 447 and 448 look like there a permanant part of the machine.

Well Matt, you can call it something else if you want.

Wikipedia does not make a distinction about how large it has to be to
be a subframe.
Subframe - Wikipedia, the free encyclopedia

A week does not go by with out a poster asking, "gee, should I mount my
backhoe on the 3PH or get a subframe?" It does not help to be saying,
you now have THREE choices:
> 3-pt
> subframe
> big-a55 brackets if you got a JD

As to the method JD uses for the 448 on 4x20s or 3xxxs, it is a very good
thing that the hoe is mounted close-in to the the back of the tractor. It may
not be a good idea to NOT have a longer subframe that transfers
more bending forces forward however. The same weight/hp Kubota L5740
uses a much longer subframe for the BH90. It certainly looks more substantial.

maybe you are talkin the 4xxx I guess when compaired to a grand L, my machine is more the size of the L3400, bit over a 1000 lbs less before the larger tires/loader etc. After doing a bit of research..the 448 looks great..just as the CX loader rocks (almost si-fi on how it comes off) JD didnt cobble it together with these combos....I'm excited to ruin the lawn

Here is the subframe for a 448 attachment on a JD4720, or one of the
other 4000 series Twenties.
