I have an LT1000 with a Briggs and Stratton 18.5 OHV Intek Engine. The engine blew, so I replaced with a 17.5 OHV Briggs and Stratton. Everything seems to be connected correctly. It starts and runs, but the hydrostatic transmission is not engaging in forward or reverse now. Also, I had taken the brake assembly apart and cannot figure out how to get it back together correctly; I'm not sure if it is related. The brake sits above the disc, and I'm having a hard time finding a picture online to show me how it goes back together. Any help will be greatly appreciated.

Make sure the push lever on the back of the tractor is positioned correctly.

If it is might try jacking it up with both rear tires elevated start the engine, place in gear and just let it set and run. You are bleeding air.
If it ever starts working you probably need to get ready to replace the Hydro.

A complete model number of the tractor might be helpful. The number from the model and ser tag.

Ill try to get the model/serial number later today. Do you meant he parking brake?
Why do you think I may need to replace the hydro? It has been running great for years.

I let it run in drive for 15 minutes with the rear end raised. The wheel never spun

No
Hydro's have a Neutral lever usually on the rear of the machine that allows them to be pushed. If it's set for push it will not drive. If it's not in N work the lever back and forth and try again.

Thanks for clarifying. It is pushed in to drive. Do you have any other ideas?

Is this how the rear brake should look?

I took the deck off and I have it lifted. I had it running and the drive belt is loose and not catching. I put it in gear and the transmission pulley is not engaging either.

You got lucky in a way, maybe.
Keep a heads up around the hydro drive pulley. If the belt comes off in that area it will sometimes ruin the plastic fan. Also when replacing the belt follow the owners manual instruction for such and also sometimes on the bottom of the left running board is a belt routing diagram.
You might want to replace the belt while you are under the machine.

Their is a reason the belt came off. Don't just put it back on and hope for the best. If you don't find out why IT WILL HAPPEN AGAIN.
You can keep one wheel or both wheels elevated and do a test drive watching the drive wheels. You may have to put the hydro in N to replace/re-install the belt.

Did you locate a owners manual with belt replacement instructions and a parts manual?
