Q:

front wheels locked up 917377531 Craftsman Rotary mower

A:

Thank you for choosing Sears Parts Direct. I will be more than happy to help with your lawn mower.  Upon researching model917377531; I show it is front wheel drive. It could be that the gear case has seized up. There a gears inside and if there is any damage inside the unit will seize up. Put the unit up on stands and see if you can freely turn the gear case axle by hand. There is a lever on the top of the gear case that a spring connects to. That lever will need to be turned to let the gear case axle turn. For safety It is best to remove the spark plug. If the gear case axle will not turn at all then the gear case could have to be replaced. I linked the diagram below. The gear case is number 36. The spring is number 43.

If you have any further questions please re-post. Thank you for choosing Sears Parts Direct. We appreciate your business. Have a great day.

Q:

I have a Craftsman 6 hp, 22" rear discharge mower with a broken pull cord. It is a model 917.377531.

A:

You have to drill the rivets out to replace the starter rope or the starter assembly. The best way to repair the lawn mower is to replace the starter assembly complete. This way you get all new parts. The pulley might be worn and that caused the rope to break. The dogs wear out and don't grip the top of the flywheel as well.

If you order the complete rewind starter assembly, you will get new bolts and nuts to replace the rivets you drill out.
