Husqvarna LGT 24K54 loses ability to go up hill

[jpilk99]

Hi all,

After figuring out my issue with the new mower deck belting jumping off (because I can be an idiot at times) I'm now working to figure out why I have a hard time getting up hills after the machine is warmed up.

If I try driving up the hill next to my house when the machine is freshly started/running, I can climb with ease. But, after running/driving for 15 minutes or so, the machine is maybe 70% effective getting up the same hill. After 20-25 minutes of mowing, I can barely climb the hill.

I also notice that the tractor doesn't drive as fast as I recall when it was new (I'd say it is still about 90% as fast) and CERTAINLY doesn't back up as fast.

I thought it was the drive belt that had stretched/worn, but, I replaced it with a brand new one - drives the same. Only thing I can think is either the drive pulley is worn or the pulley at the rear of the machine, or I guess the tension in the drive belt circuit is keeping it as taught as it should.

Thoughts?

Thank you.

Jay

Tender Torq K46 trans is failing.

Exact same thing mine does, won't climb hill after it warms up. Needs transmission work.

Yaks! Quick search shows new Tuff Torq K46 units for $600 or so. I see rebuild kits for $225.

Any DIY videos or write ups.

Thanks for the Replies!!!

I'm not sure if your mower had the big lower steering shaft support plate. If it does,they collect a lot of grass and sometimes prevent the clutch / brake pedal from fully retracting, so it is like "riding the clutch". A good thing to check first.

I think a new tuff torq is over $1000. I recently emailed tuff torq about mine, they gave me a list of things to check, attached.

I just replaced a broken axle in mine last yr, and posted pics somewhere on TBN of it opened up.

There is a serial number tag on the back of the K46 that identifies which k46 version. You need this when talking to tuff torq about parts, or you can go to website and look up parts.

Thanks all.

Gator, great link - very detailed. Tom, not sure what size steering mechanism I have, but, it looked pretty clean in there. It doesn't feel like brake is engaged at all. Not sure if I mentioned, but, not only does getting up hills get tough once warmed up, but, backing up is pretty beat. (see pics)

So, it looks like I have a 46A?

46 means k46, AW is the specific k46 you have.
