I have been looking for service manual ?

I have a 1995 MTD Yard Machine Hydrostatic lawn tractor.
I cannot find the service manual for the transaxel the part number is 718-0255.
I have seen some you tube videos on lawn mower transaxel rebuilding but they must have had a service manual to order the parts. after mowing a half acre my mower will not get on my tilt trailer. I want to rebuild the transaxel.
