MTD runs only one speed

[Fish]

The center sheave moves up and down, giving the rear end a variety of speeds like a 10 speed bicycle. I have been known to give a light squirt of wd-40 there, but since the belt runs on both sides, just a quick little squirt.

likely your variable speed pulley is jammed and not sliding

I hope to get up on my lift today to look at it. A couple people have suggested that. Thanks for your input

Sometimes if belt starts to fray pieces of belt can get stuck stopping movement. If taking apart there is a fiber/plastic washer on top. NLA but ebay had some in the past. Or match up at hardware store. Had one where roller bearing started to seize. Ebay has pulley assembly if needed, factory NLA.

Considering it ran before the brake adjustment, loosen it and see if you get back to where you started. Then look at the drive belts for cracking of burned areas. With the brake on, you should be able to turn the idler pulleys (depends on model).

I assume the only way to this is through where the battery sits? Do you have a link for the eBay part?

Through plate in front of seat. Good idea to change both belts.

Try resetting the pedal if it is a varidrive setup. Start the tractor. Put shifter in neutral and speed selector in highest gear then release the brake while still in neutral until the brake pedal comes all the way back. then put in forward and try it. Sometimes this needs to be done if the machine stalled or ran out of gas
