Sears Model 917.378590 22" self propelled, front wheel drive walk behind mower. I cannot get the blade adapter off to remove the debris guard so I can access the belt pulley to change the belt. I can't tell how the blade adapter is connected to the engine pulley .

Thank you for your question and I understand your concern.

The blade adapter just slips over the end of the crank shaft and it held on with the bolt. The blade adapter most likely rusted onto the shaft. Spray some rust buster around the top of the adapter and let it soak and then see if will come loose. You may have to use some type of puller to remove the adapter if it will not come loose and pull off.

 I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post.

You are correct. The adapter was just seized on to the pulley shaft, I removed it yesterday by jury rigging a steel bar and two c-clamps. It had never been removed since I bought it in 1994. New belt on warp drive returned to full power..... Thanks for the help. Ed

Q:

How's the speed controlled on a Sears mower 917.378590 110893M012041?

A:

The engine has a governor inside the engine that regulates the high speed rpm's it is designed to run at high speed whenever you are using it.

Small engine manufacturers all agree that you do more harm than good by slowing the speed of the engine. The engine is cooled by a fan on the flywheel and when the engine is slowed down it will run hotter.
