After attempting to edit the post above unsuccessfully (time expired), I'll have to post a new message with updates:
1. The Bobcat MT50 is just that... MT50. There is no "1" in the model number... I might have been thinking of the T190, which is to large for fitting through garden gates.
2. There are several other brands and models in the chariot/walk-behind style that could be added to the list, and will be in #6 below.
3. The chariot/walk-behind style is considered to be realistically comparable to the Bobcat 463 for several reasons:
a) the 463 is in many cases a lot LESS powerful than the chariot/walk-behinds listed here, both in motor horsepower rating, as well as in hydraulic flow of the pump expressed in GPM.
b) the strength and stated purpose of the 463 is it's ultra tight quarters manuverability through limited access corridors. Not only is the 463 marketed for narrowness, it is advertised as being one of the shortest in length as well as the least tall (under 6 feet). Well, many of the walk-behinds and stand-ons have the 463 beat on all three dimensions, and coupled with better or equal lifting power, accessory hydraulic power, and horsepower, present a formidable competitive challenge to the 463... which makes them worth considering.
4. The Toro Dingo model line was possibly listed incompletely. I believe that the model series is as follows:
Toro Dingo 220
Toro Dingo 320D
Toro Dingo 322
Toro Dingo TX 420
Toro Dingo TX 425 wide track
5. In this world of ancronyms, it is hard to strictly distinguish the catagories that define the class of machine that meets the use qualifications set out in the parent post of this thread. All of the following have been found here:
CUT... Compact Utility Tractor
CUL... Compact Utility Loader
CTL... Compact Track Loader
MTL... Mini Track Loader
ML... Mini Loader
MSL... Mini (Something or other) Loader
and so on and so forth. The definitions of what machine fits into what catagory vary as vastly as the editors and writers who review these pieces for the rental industry rags.
Again, for the purpose stated here, to make it on this list, SIZE matters most. As long as the machine is not a radio remote control monster truck replica from the toy store, and as long as it almost meets or exceeds the work capacity of the Bobcat 463, it qualifys for comparative inclusion here.
6. Here is the list addendum, but unlike the first list in my post above, not every single model in this addendum below has been verifed to be less than 48" wide, as time was too short at the moment to fully investigate. Some manufacturer's website are time consuming and laborious to wade through to find the core product dimensional specs. Nonetheless, most all of these machines should qualify:
(Edited to re-include the models on the original list posted earlier, to keep the entire list intact:
ASV RC30
ASL (by Polaris, rebrand of model above)
BARNTek (No model data, geared toward homeowner use)
Bobcat 463 (Wheel)
Bobcat MT50 (Track)
Boxer TL-224 (Track)
Boxer TL-224-35
Boxer TF-224-35 (Track)
Boxer TF-224-D
Boxer TF-224-43 (Track)
Boxer WF-224-41 (Wheel)
(Boxer Note: There may be some redundancy in the above models listed, as they came from 3 different sources, none of which were Mertz, Inc., the corporate manufacturer of the Boxer products.)
CASE 1825XT
CATERPILLAR (No models known to fit size criterion)
CF Struck (See "MagnaTrac" below)
Cheetah SS16 (Wheel)
Cheetah SS20-D (Wheel)
Dingo (See "Toro" below)
Ditch Witch SK500 (Wheel)

Gehl AL 20 DX
Kanga DL-520 (Wheel)
Kanga KK-113 KID (Wheel)
Kanga G-520 (Wheel)
Kanga G-524 (Wheel)
(Kanga Note: Kanga is an Austrailian brand/company. Those guys down there are really into this mini-loader phenomenon. In fact, the Toro "Dingo" line was reportedly also developed down under, and a refugee employee from that team reportedly branched out and started Kanga. Or, it could have been the other way around. Rumors, ya know.)
MagnaTrac MD200 (Track)
MagnaTrac MD750 (Track)
(MagnaTrac Note: New to this list, the MagnaTrac is actually a mini caterpillar D1 dozer style tractor which has loader attachment that makes it work like a tracked 463. The manufacturer of the tractor as well as the attachment is CF Struck. They make larger, heavier MagnaTrac models, but only the two models listed above fit the small size criterion.)

Toro Dingo 322 Kohler Gas (Wheel)
Toro Dingo TX 420 (Track)
Toro Dingo TX 425 Wide (Track) (Still under 48")
Lots of choices, it seems. The list above is growing to be the most comprehensive collection of competitive alternatives to the Bobcat 463 that I have found on the Internet... obviously, because I've created the list by combining all the other incomplete lists into one. Hopefully, others will fill in any holes in this list, and add commentary on their personal experiences with the models thus far listed.
