Hi Chris-

I also found this link regarding your Husqvarna YTH2348 owners manual (OM) lawn tractor.

Hope this helps.

Lock under the mower, is a belt slipping or may has come off a pulley ?

Not sure what all you checked but did you look at your drive belt? If it slipped of the pulley everything will still work just fine but it want move.

very common problem "fast in forward, but slow in reverse" is what I hear at my shop all the time nothing you can do, factory made problem for 80% of mowers these days

bad reverse check valve take it in about 100.00

You need to check the cable, it is a push pull telescopic style so it is possible to get forward and no reverse, if it was a hydro problem you would not get forward or reverse, there is also timing gears on the forward and reverse pedal, you nee to make sure they have not jumped a tooth as this would reduce movement on the cable at the hydro

your rear end is going bad and they are realy exspensive, buy a new mower.

check the linkage and make sure that it has full travel

It sounds like the problem is in the power sterring pump.

The timing is either 180 degrees out or you have got it in reverse. Look in your user manual
