The infamous variable speed pulley is stuck and not responding to the changes in spring tension that is placed on it with the speed selector.

Have a good look under the mower there should be a belt from the engine ans another belt from the rear axel and both of these should end up on a single pulley.
The top & bottom flanges of that pulley are fixed but the middle one can slide up & down.
This changes the circumfrences of both pulleys one gets bigger so that belt goes slower & the other gets smaller so that belt moves faster..
If the sliding member can not move freely up & down the mower speeds can not change.
All of this is controlled by a whopping big spring.

There are a few variations on the theme depending upon how the belt tension is maintained.
some have discreet tensioning pulleys while others the double pulley itself is on a pivoting arm.
So get it up in the air and have a look.
Usually you have to remove the battery & battery tray to get access to the rear pulleys.

This system is very sensative to belts and the belts used are usually deeper than standard mower belts and they must be wrapped.

I believe this is what is thought to be your problem (item with big silver pulley &
triangular bearing cup on bottom) this item (new) usually ..$145.00 --$245.00

Also in the diagram the two clutch pulleys ( 63) can give you grief and cause loss of drive if they do not pull the belt tight enough.

Berts-Man - You're the bestest!!!

I do have a question though... What do you mean when you say that the belts "must be wrapped"? Heck, I'm "wrapped", just not very tightly!!!

Hey Rog, I think Bert is referring to a type of belt that has a final outer layer of Kevlar or "glass -cloth"
to provide additional strength and wear .......... ( sorta like better quality & money ) and yes we ALL know you have a "loose coil" somewhere !!! ( LOL )

The outer cover is usually either pollyester or cotton.
Id does nothing for the strength of the belt.
Plain belts like on your cars fan are not wrapped and just like your tyres get sticky when they get hot.
A hot sticky belt will not slip when you take the tension off it which is why mower belts are wrapped in most instances.
ZTR belts do not need to be wrapped because there is no slipping clutch pulley.

Berts Man - I Knew I could count on you to have an accurate and detailed explanation.. At least you aren't all concerned that I'm sitting around lamenting and considering cashing in my chips.. That ain't gonna happen! . . . . I just figure it's good for my mental attitude to bitch about what bugs me, know what I mean?
I can't say that I've found a lot of benefits to growing older, other than it beats the crap out of the alternative, oh - and the senior discounts you can get. I like a discount as well as the next guy...
