Does anyone know what are some common cause of why my MTD Lawnmower's blades will not spin?

Well, the blades turn on pulleys and belts. So I would check to see if a belt is broken or has come off the pulley.

They might have a rope or something similar wrapped around them. Have someone else check for you, so that the motor doesn't turn after you unwind (chop off your fingers). The engine might have quit. You need to get the blades sharpened every year anyway, so why not have the mower serviced? Here, it is only about a $20.00 job. They can evaluate the condition for you.

The lawn mower is running, but the blade is not turning. It is a Toro, model SR4 Super Recycler.

My only suggestion. A blades are driven from the engine thru a belt and pulley system. I would check to make sure the belt is riding on the pulleys when engage to mow.


Sometimes they slip off the pully. Also make sure the belt is not broken.

There is a pin that can be sheared if you run over something while mowing,if the blade spins freely or you can spin by hand,this is most likely the problem

This could be a pulley or even a cable problem. You'll need to check the cable release for the blades and make sure it is working correctly. If the wire to the release is not moving then it needs to be replaced. At times these wires will break and they have to be replaced.
