Lawn mower problems?

Posted by admin
SapphireB asked:

I have a Murray 22″ cut 4.0 HP Spirit push mower. I was mowing the grass and it was running fine.I decided to replace the blade on it as the blade was worn out. While I had it on its side, I decided to change the oil in it as well. I cleaned out all the grass that was caked on under the deck. I put the lawn mower back on the ground and was going to try to start it as I was going to mow some more.The mower is only about 2 years old. I have only had to push the primer button 3 or 4 times and fires right up every time. Anyway, when I got ready to start the mower, I pulled the cord on it a couple of times and it locked up on me. I could turn the blade manually (hard to turn) but I turn it and free it up and pull the cord again and the same thing would happen again, it would lock up.I have done this same thing several times, it locks up I turn the blade manually and 3 pulls it locks up. Help me out, what is causing this problem.
The blade will not turn at all now even by hand, it is locked up tight. I have removed the spark plug all the way. Would it be ok to drain all the oil out now and try to pull the cord again? Not to try to start, just to try to free it up?
I have drained all the oil out of it. It is locked up tighter than a drum. I can’t get any thing to move at all.I wish there was someone that could at least email me about this so that they can walk me threw all the problems that I am having with it. My dad worked on mowers him self for over 50 years, but his is now 83 and can not help me with this problem. He thinks that it is a piston that is causing the problem. The mower was running fine and not making any kind of noise at all.I can not afford to take it in and get it fix.I’m trying to learn how to fix things myself if at all possible to save me money. I need some more help here please.
I have taken off the top part of the mower where the reel coil is at. Pulled the cord and it pulls freely and rewinds back in with no problem. The fly wheel will not turn at all.At one time I could manaully turn the blade even though it was hard and get it to moving a bit and then pull the cord a couple of times before it would lock up again. But can’t even do that now.

I will post it on here with this question when I do get this problem solved.So until you see it wrote here that it is running yet..it is still locked up.

      Jeez, EVERYONE is right… Always, when getting under the deck, raise the mower so the plug is skyward. If you do this, you will not get the oil accumulation in the cylinder and air cleaner… Makes a real mess when it takes off, and plugs up your air cleaner… Simple fix, wish you luck !!!

      The cylinder is actually letting go when you hold the flywheel take the handle down is free of any oil make sure the shroud off bolts to get good look at it.

      The oil will flow into parts of mower where it also when you.
      The blade all the spark plug out and clean it shouldnt be good luck.
