That looks to be about the same Toro that i have. The bail to brake the engine and run the self propel is a single unit and do get out of adjustment as well as break or become damaged or out of sorts from catching the cables on something as well as just wear and tear. I worked on mine about 3 years ago and do not really remember anything difficult about it. Removal of the transmission cover exposes about everything you need to get to. Take a good look at the belt while you are in there. The belts on those last a long time due to the type of transmission but they do get worn out. The belt for mine was available from Oregon.
