Get some leather gloves and a socket wrench set. Lean the mower
over by raising one side so you can gain access to the blade. Be
careful not to pour out any fluids. Work from the side of the mower
that has the grass discharge (the right side). With something holding
the mower at a tilt, grasp the blade with a gloved hand and loosen
with the correct socket the nut under the blade that is in the center
of the blade. As you loosen the nut, the blade will begin to lower.
Be careful that you do not lose any of the mechanism, and notice
the way it fits together. Just replace in reverse, but a tip is to put
a little bit of grease (very little) on the threads of the bolt that holds
the blade. Tighten well. I frequently take off my blade and sharpen
it. Are you sure that it needs to be replaced? Can it be sharpened?
Remember: "Lefty, loosy; righty, tighty."
If this is the 500 series Weedeater mower, try Walmart. They have this mower in stock.
Drain plug is next to the blade Place a ratchet head into the square plug and drain oil Replace plug and replace oil

The opposite direction that the blade rotates. In this case I would say counter clockwise but their should be a marking somewhere on the mower that shows blade rotation direction.

Shouldnt be a problem. Just check and make sure the spindle is the same size.
Most modern mowers are of the rotary type. Rotary mower engines are all made to spin at 3,600 revs per minute when not under load. During cutting, the rpm drops to between 2800 and 3300. There is a simple wire-based device for measuring rpm on a running mower, which all mower specialists would own.The other speed linked with your question could be that concerning the velocity of the blade tip as it revolves. As the centre of the blade is spinning at 3600 rpm, an 18 inch blade tip will travel through the air at one speed a 21 inch at a faster speed and so on. Rotary mower blade bars are made up to a max of 24 inches.
