Husqvarna YTH24K48, Foot Pedal Vibration and Grinding

Good day, everyone.  I have an issue with my Husqvarna YTH24K48.  The lawn mower is 5 years old with 124 hours on it.  The only notable thing: in the Fall we use our tow-behind leaf sweeper.  Yesterday the foot pedal started to pulse back at me and it made a slight grinding noise.  It would not let me press down all the way.  I was able to finish mowing my yard in super-slow speed as the pedal allowed me to slightly press down without issue.  After the cut I used by hand-held leaf blower and blew out all the debris but that did not help.  After some research I think it might be the drive belt?  Does this sound right to anyone reading this?  Thanks very much!  Jimbo

The only mower I work on that a pulsing pedal turn out to be a broken axle.

The model number you posted only matches mowers that are more then 5 years old. The newest mower listed is 2004. Look under the seat for the chassis model and serial numbers. This mower uses a hydro drive trans axel correct? Sounds like the system is low on fluid and air bound creating the pulsing. It really could be a number of different things causing this.

Hi jrrdw, Yup, my mistake, here is the correct information: Model: YTH24K48  Product: 960450035  Serial: 052313A027725.  I bought it in July 2013 from Lowes.

Did you check the fluid level?

No, how would I go about checking the fluid level?

I believe that is a sealed tranny

Yes the transaxle is sealed unit being it is Tuff Torq 46BT. The only time fluid is added (actually changed) is during repair of the transaxle because either internal problem or seal replacement.

Any sight windows or reservoirs on this model?

Basically you have to pull the transaxle to check it; hence , the no enduser access provided comment. If someone is wanting to check it here is the instructions provide by Tuff Torq.

Hello everyone.  I wanted to give an update and a question.  I recently brought it to my local power equipment company and today I got a call that it is, indeed, an internal issue with the transmission.  He said there is no real option other than putting in a new (same) transmission.  He said the model number has not changed (same as the broken one I have on) and he thinks I will have the same issue again in 5 years and 132 hours later.  I asked him about putting in different fluid that I read was recommended on the net and he was reluctant.  I asked him about retro-fitting a John Deere tranny I read about on the net and he said no.
 
My question to the forum:  I believe our heavy use of a leaf sweeper broke the tranny.  We have a full 1.5 acres (not much woods) and we have quite a bit of trees.  Would using a bagging system (3 bagger from Lowes) instead of using a leaf sweeper be easier on our transmission?  I am trying to think of all options here.  Thanks, Jimbo

My thought process being that the heavy weight is above the rear wheels instead of behind the rear wheels.  Thanks very much, Jimbo

Hi Jimbo:
See my post about adding drain plugs to your transmission (THE DREADED TUFF-TORQ K46).  One year down the line and mine is working just fine.  Even if you have trashed the internals on yours, replacement parts / rebuild kits are available from Tuff-Torq and they were very knowledgeable and helpful in providing information and guidance to me.  If worse comes to worse, you can purchase a new unit from them and replacing it is not that hard if you have any mechanical skill at all.  For the record I would go with the bagging unit in the future, the K46 is not designed to be used with ground-contact equipment.

Yeah, I had the new transmission installed at the local power equipment shop.  It runs mostly fine now.  There is still some vibration when I go uphill.  We are either going to outsource our leaves or get a bagger unit.  Thanks for the responses.  Jimbo
