I have a 26hp Kohler with a 48" fabricated deck and the Husqvarna XLS package. What model of the tuff Torq tranny does it have and more so, what is it safe doing for attachments. I have towed many trees with it, the key is using the hydrostatic slow and "feeling" where it is comfortable. With 26hp you need not worry about speed, just let it go slow and easy. I must say that having the auto differential makes moving around the extremely steep and varied landscape here a breeze while mowing. No switches to interfere. Thanks for any replies!

K66 K72 qnd K92 are the only ones with Differential Lock. K92 is standard and the other 2 are optional.
I made an incorrect assumed it was K72. I could be any of them.
I'll go back and look at the ad which I could have got wrong. Anyway another thread here (I think) spends a lot of time talking about the limited slip on the Husqys. The issues seem to be whether there are two kinds of anti slip gears in the diff: Electric via dash knob
and /?or "built in" (like auto clutch pak) unit. Also if the electric is total lock up which can affect steering and tear up turf. I can't think of an issue where there is more confusion with the Model number and what it means than the locking feature on Husqvarna. The local dealer was confused the one time I visited. An finally can a locking feature be had on Husqy with a Kaw engine? Thanks
I looked at Partstree and it showed K46, on Husqvarna site is says auto locking, I wonder if it is like the old positrack rear ends that would lock in when one wheel starts to spin ?
And....to keep the dialog going. With a car with open diff (no lsd) when stuck (as in snow) I have successfully used the foot brake while gently pressing on the gas to get out. Several responders have also referred to success where they have foot pedals, but I don't know enough about the universe of tractors to know if those pedals are brake pedals or diff lock pedals. Anyway I have not tried to brake my DYT4000 when one wheel is spinning. Maybe that is a poor man's "sometime" lsd. The delta cost appears to be about $300 to get the lsd on a Husky once we can decide what model actually has one. One frustrated owner says he bought new and it took him a year to decide he did not have lsd on his husky, contrary to what the dealer sold him. Bummmmmer!

Easy to tell. Jack rear end off ground and spin tires. Both spin same direction then yes if they spin in different direction the no.
I looked again at Jacks and no call out there for the trans type on Husq GT48XLSi. I pulled up the manual , 72pp, and no call out there. Very little in the manual on the lsd .
Only that it should stop before actuating switch on dash. Mentions is will tear turf. On the hill section no discussion at all of the lsd which seems weird.
Mowers Direct does specify K 66 on the Husq GTH52XLS. Also they show Cub Cadet GT 50 with K 58, apparently non lsd.
Motoman you are correct the GT48Lsi has a K66 I looked at one late last year at dealer.
The OP said it was YT48XLS and I looked it up on Partstree and it showed K46.
I wish origional poster would come back and let us know for sure what he has and serial # of tractor.
I find the model designations of lawn tractors a baffling hodge podge of gobbledegook which is a moving target. By the time I focus on a model I want to price out it no longer appears. Just like consumer reports on almost anything I look at..TVs to paint....Oh, that model is superseded. What a cluster f. Anyway perhaps the "i" suffix signifies lsd on the Husqy? Further, Craftsman doesnt even show the main model number now, instead a multi digit numeric model which tells nothing. Anyone who provides a decoding for us will be applauded.
I apologize for the delay, had to get the phone and internet and all that tech replaced. Thank you for all the comments and research.
2015 Husqvarna model YT48XLS made in Orangeburg, SC (serial number 060214A1200) with a 26hp V-Twin Kohler engine.
Belt driven transmission. Transmission has a sticker that reads TUFF TORQ 7A646084321 S/N: 46CRO125196
HOP PN 42121
The transmission is an AUTO locking differential (no manual activation). Like gainestruk said, it is just like Posi-trac. I even have GOAT sticker for the rear of the tractor:laughing:
If you try to turn too fast or have the wrong tires you can rip the turf up. Just drive it like a larger tractor, no whipping around trees and be very easy with the hydrostatic pedal. I can mow the property faster now, and not get stuck or fear about sliding down a hill.
The 2015 left the Kawa motor for a Kohler, and the new fabricated deck can mow down small fields like nothing while still protecting you if you run over a mine. Of couse they added a "Turbo" pulley on top of the right mandrel to make bagging grass easier. They never thought that the taller mandrel hitting the bottom of the frame and reducing the height you can raise the deck, need I even say engineers?:thumbdown:
I am considering installing a Mojack Hitch + System - Multi-Use Hitch Model #48401. Any experience or comments on if it with make towing safer for the tractor and frame? Why do companies require a minimum of 22" rear tires for a sleeve hitch?
What are the taller, narrower tires and wheels for garden tractors for? I understand the increase in torque demands a larger diff, but wider tires have more rubber on the terrain. Why not a smaller, wider "mowing" tire with a larger differential? Basically I want to pull and push, load and dump with diff attachments. I just do not wanna tax the machine too much. It needs to last. 26 hp could put this tractor and differential to pieces, so engine power is no problem. It seems the ground engaging equipment is hard on things as the 'ol Ford LGT100 is like a mechanical bull when roto-tilling with a PTO shaft. The Ford is not mine though.:frown: They just do not make things like they used to, but I would like to take advantage of what they do make now. In the future the mowers will just operate the humans like the kids and their "phones" now.

All the GT's I've dealt with have taller wider tires. I have not looked at new models.
Why do they have taller wheels though. Is it because they sink into the dirt when using ground engaging attachments or do they make snow plowing and pulling light attachments and or carts wagonswith large loads easier?

Small tires would slip and spin easier with the torque needed to move the ground engagement.
I am being very careful to get that one "right" garden tractor replacement for my Craftsman dyt 4000 which cannot do things I know now that I need. I'm hip that the 1" dia axles go with the "garden tractor" and a more rugged transmission, but I have learned that a model name can be of some help. For instance if you want ground engaging toughness avoid LGT designation as the "L" is for light. But manufacturers are purposely very coy about their marketing names, and as I have said prviously Craftsman is very bad right now with their so called "specifications." I have reviewed "Iron Search" looking at compact and subcompact tractors. "Used," they start at around $6K so buying a proper GT rider fills that gap if you can navigate the poor dealer knowledge and be sure what you'e getting. I paid a pro $4K last year to put in a front lawn I could have done with a proper GT rider which could break weedy , dry soil.

The Craftsman dyt 4000 was built by Husqvarna by the way.
