Question about Mtd 22" Yard Machine Push Mower

1 Answer

Flywheel moves then stops

My 123 cc Yard Machine push mower was working fine last week, now today won't start. I took off the pull assembly and flywheel nut, if mine has a key it's different than the pics I've seen on the internet. The flywheel will turn freely when the gas handle is pulled (which also released the brake) but then it hits a "wall". The brake had an edge that's still touching the flywheel and not sure than it would make a difference.

Any ideas about a next step? Thanks in advance

If the engine only turns half a turn or so and feels like it hits something solid my guess is a broken conrod inside the motor(check your oil level??) dismantle engine to inspect damage

How to replace the cranking pull cord?

Ok, the spring will more than likely unravel when you remove the pull cord cover/assembly. There is notch in the spool for winding the rope around it. So make sure the spring is wound enough to fit it in the housing. Then take the rope, already knotted and in the spool. Turn the spool in the direction that tightens the spring.Push down on spool and allow spring to retract the rope. (Don't forget to tie the knot in the rope handle before placing on mower). Then lightly clamp in vise or visegrip, or channel lock pliers. I like to use visegrips on one side, and channel locks on the other. Place over the square flywheel nut,release channelock pliers, hold with fingers tightly so the spring does not unravel. Then release visegrips and hold with other free hand, Place over flywheel nut and slide down. Re-attach with screw previously removed. Your done. Don't forget to tie the knot in the rope handle before placing on mower.

I was mowing my yard, and the grass was pretty tall. (4-5 inches, maybe 6 in some spots). I hit a tall spot and the mower started to struggle (usually recovers), but this time it didn't make it through. ...

It sounds like the flywheel key is bent and /or broken. You have to remove the flywheel to check. Remove the part containing the starter rope. Under, you will see the top of the flywheel. Remove the nut holding the cup to the flywheel.If you have a wooden mallot, lift up on one side of the flywheel and rap the shaft with the mallot. If you dont have a mallot, find a nut with the same thread as the shaft. Wind the nut on so the nutis just above the shaft. Now, holding the side of the flywheel, rap the nut with a hammer. You may have to do it several times.When the flywheel comes off, check the flywheel key. It should be in a slot on the shaft. Get a new one and replace it in the reverse order that you took it apart.Please be careful and REMOVE THE SPARK PLUG WIRE BEFORE WORKING ON THE FLYWHEEL!! Good luck...Lee

Poulan 550 Series push mower won't pull start

Hmmmm,,and the plot thickens. Without seeing the unit, i would have to think that when you pull the engine control cable bar, its not releasing the brake that sits against the flywheel. These cables do stretch. Pull the engine cover and you will see the brake against the flywheel. Pull the engine control handle and watch and see if brake is releasing. If its not, replace the cable.
That would be my bet. I hope this is of some help.
