My friend has a Husqvarna with a Tuff Torq K46 that is weak, it doesn't want to go up hills.  He drained the fluid and replaced it, someone told him that was a good idea.  Didn't make any difference.

Any hope of a rebuild or better off to just replace it?  I read on another tractor forum that the oem will rebuild it, and upgrade for 500 bucks.  Sounds like a decent deal. 

Anyone have any experience or insight to offer?

My coworker rebuilt a K40/46 in his JD, same thing was happening. They did the research, bought parts ( about $200) rebuilt it then after it got warm, it started the whole thing again. Not sure what they didn't do or what was too worn out in the case. They ended up selling a 300 hr JD mower for like $250.

If you can find a used upgrade, I think it's a K66(?), then do the swap.

I used to work in a garage and the first thing everyone wanted done when they started having transmission problems was have the fluid and filter changed and I don't remember one time of that fixing or even helping the problem.

Is the K66 a direct bolt in?  Seen there are kits for 1700 dollars on ebay.  Seems like you may need to change your wheels?  Or hubs?

 

Seems like from what you guys just confirmed that if he rebuilds, or buys a new K46 then he will have the same problems right down the road.

 

He said its a good tractor, and he doesn't want to buy a new one.  I tried to sell him the cub 128 restoration project(that I never started) tractor for 500 bucks, but he wouldn't take it.  Runs and cuts great, just really crusty from being stored under a tarp outside for 40 years...He said he doesn't want old junk, I guess his new junk is better!

As to the K66xx upgrade, there is RJR tractor that sells the complete kit for about $2500. All parts included except for the tires. You use your own and just have them swapped to your wheels.  The biggest change from the junk K46 series to the K66 is going from the 3/4" axle (actually a 1/2" thanks to the keyway cut into it) to a full 1" axle (3/4" thanks to the keyway). On the K66xx series, you can change the oil; there are ports for hydraulic steering or other options; allows you to use a better quality plow and it's rebuildable compared to the junk K46.

If someone were to spend $2,500 on upgrading the hydro on anything that originally had a K46, they should be institutionalized.

 Cat385B. Do you feel the same way about replacing the engine or any part of the drivetrain in your car or truck? Or how about the body panels? Replacing the rear K46 with a beefier unit is a heck of a lot cheaper than taking out a loan or mortgaging your house to buy a costlier machine. Especially when the frame and body can sustain the torque and power output from a far superior trans. If I could afford it, there'd be a Kubota B2120 in my shed. But like many others, $10K+ just doesn't fall out of the sky to satisfy our dreams and wishes. So for now, an upgrade kit is financially the only option for many of us.

To each their own but IMO, 2500 could buy this in running and mowing in most areas. Give or take a few.

Your second line is my point, but my opinion is opposite. I don't think any machine originally sold with a K46 can handle the tasks of a machine that was originally equipped with the 66. You mention a better plow, for instance. The K46 machine was not designed for, nor can it withstand, a larger or heavier plow. The front axle was not designed heavy enough to handle that.

In reference to your comparison, if the 5 speed manual in my little 4 banger Chevy Aveo took a crap, I might replace it with a used one. I certainly would not replace it with a six speed out of a Camaro or Corvette.

I have to agree with CAT ( did I just type that :poke:  :D ), the machine that originally had the K46 was probably originally bought for cheaper than the K66 upgrade @ @2500. You could most likely go buy 2 brand new box store unit for the price of upgrading the used one or at least just replace whole tractor with a new one.  

I'm pretty sure I've seen other placed that you can buy a brand new K66 for a lot cheaper than $2500, may not have been a complete kit.

Tractor date calls your White a GT and shows a rear sleeve hitch and larger attachments. I would say you are safe. If it has a Tuff Torq brand transaxle, it probably has a K66 or K71.

 

The K40/46 style was used in mainly your "lawn" tractors and most box store mower style tractors i.e. smaller riders.
