Missing return spring (on mine, its on top of the deck forward) or sticking mechanism. With mower off, you should be able to push back on the idler pully and the deck belt should loosen up. If its sticking, pull the deck off and see whats causing it (may be stick or dried grass). If its missing spring, dont try any old spring from hardware store (hmmm could this be from experience???), but order one from ebay or amazon or whoever has it cheapest.

What are the Causes for Mower Blades that Won`t Disengage? The causes for mower blade disengagement are the loose engagement lever and the worn-out idler rod and cable. Other causes that can cause these bade problems are missing springs, defective idler arms, and mounting defects.
Worn or broken blade drive belt – If the riding mower blades are not spinning, the blade drive belt may be worn or broken and unable to engage the blades. If the belt is intact, inspect it to see if it`s loose or slipping on the pulleys then replace it with a new one if necessary.
A lawn mower blade can get stuck for several reasons, one of which includes over-tightening. Lawn mower blades are supposed to be loose enough to slip when they hit a solid object in order to protect the engine and the blade itself from damage. Lawn mower blades may also get stuck if the bolt is threaded the wrong way.
Power take-off (PTO) clutches provide a mechanical disconnect between the power created by gas and diesel engines or electric motors to another piece of equipment. The PTO clutches enable the transmission of that energy to auxiliary equipment that does not generate its own power.
Generally speaking, the blade should be tight enough so that it doesn`t move around on its own, but you should be able to move with your hand by applying some pressure. The manufacturer should provide a proper tightening level expressed in foot-pounds, commonly found in the mower`s manual.
If your blade doesn`t and you weren`t able to reference it to the old blade, look at the cutting edge of the blade. Most lawn mower blades rotate in a clockwise direction (counter-clockwise when viewed from below), and as such have the cutting edge on the right side.

I need to get the blade of the lawn mower sharpened.Any tips on how to disconnect the blade fropm the lawn mower?
There is a jig that you can buy that makes this job SO much eaiser. It is a universal jig that clamps onto the deck and keeps the blade from spinning so you can use a ratchet to remove the nut holding the blade on. One name brand is called a “Blade Hog”. You should be able to find one of these at one of the bog box hardware stores.
Hope this helps,

Lawn mower cranck but wont start…
Since you already checked for spark and air I would drain all the fuel out of it and check that fuel for water. Over time some lawn mowers end up with contaminated fuel. You can see the water sitting on the bottom of the fuel if you let it stand for a bit in a small plastic bowl.
Be sure to empty and dry out you fuel can as well. Especially if the mower stopped running right after a refuel. Which is a good sign your gas can is contaminated too.
Where is oil drain plug on MTD mower – Mtd LAWN MOWER PART # 683-04163B FRAME Assembly:RIDER
If it isn’t on the bottom of the engine (above the blade) then you don’t have one. This is not that uncommon. When you need to drain the oil, FIRST- pull the spark plug wire off!!! Then remove the dip stick or filler plug and turn the unit upside down and drain the oil.
I would like to replace the mulching blades on my Sears Craftsman riding mower with regular cutting blades. I can find plenty of sources for new mulching blades, but not cutting blades. My mower is a model 917.259541 tractor and the blades currently on it are part #134149. I want to make sure I get the right size to replace them. Also, is there a source for a bagging system for this mower, that won’t cost as much as one from Sears?
The straight blade for the 42 inch mower is 138971.They cut better and are easier to sharpen and you will need them if you use a gass catcher. If you do not want to use sears for parts you may be able to find good deals on ebay.
I have had a poulan pro 550 series push mower for almost 1 year at the end of the season last year the mower would start briefly and then stop. i have cleaned out the air filter and that did not help.the mower started, i made one revolution around the yard 3/4th of the way the mower quit. I then primed the mower it started then quit and now it will not start at all. Does anyone have any suggestions of what to do. Thanks
There is a little spring that works the carburetor arm. If that popped off then the mower will not run.
