Craftsman 6.75hp self propelled mower starts and turns off

SAE 30W

Take a good look at the wheel assembly. Is it rusted on from being left exposed to the elements? Remove the cover for the self propelled mechanism. Is the drive belt intact? Try turning the small pulley.

Cathy, there is a way to adjust belt tension on some models whether it is by the cable or a slotted bracket where the idler wheel is mounted, depends on make and model. If you have your manual check in it for belt adjustment. Could be stretched belt, stretched cable, worn/oil on pulley, seized tensioner, stretched/broken spring on tensioner,etc.

oil has either run into the muffler or the air filter assembly clean out and good to go.

Try reposting with model number. Need to see parts list so we can make decision.

Oh my, that is so annoying. There is probably dirt in the carb. or the gas tank. What I think happens is, the dirt gets sucked up into the fuel line and clogs the carb, then when the mower sits for a while the dirt goes back into the tank for another couple minutes. I have absolutely no tolerance for this when it happens.

look on craftsmans website and see it they have the wheel or look on partstree.com and they might have it!! have fun!! :)

Is the lever pushed up where the self propelled should be engaged? Yesterday, my wheels stopped turning. I have a break in the cable that goes to the self propelled. I will have to replace the cable.

Could be a stretched out/broken belt, a worn out transmission or the drive teeth on the inside of the wheels could be worn out. I would start by looking at that. Remove the drive wheels and check for damaged or missing teeth.
