Did you bend the crankshaft. To check this out remove spark plug wire and tip mower on it's side and turn blade by hand and watch the shaft the blade is fastened on to. There should be no wiggle motion what so ever and if there is it may be bent causing the engine to not operate properly.
i would guess that the belt is'nt tight enough when engaged. when you press the drive bar on the handle it should make the belt really tight if not it will need replaced. sometimes the gears in the wheels will mess up. there are videos on you tube that describe that and also the belt.
Most lawnmower blades simply attach with a bolt through the blade which bolts into the bottom of the crank shaft. The blades usually have a curve at the end of the blade, and this curve would point up when properly installed. If you post the model number of the machine, I can probably point you to a schematic which will show exactly how your blade mounts.
The blade adapter is a "slip fit" on the crankshaft and is held on by the blade retaining bolt. However, due to rust, etc. they can become difficult to remove. You may try penetrating oil to help loosen the rust.
We generally use an air tool to remove stubborn adapters but you have to exercise caution so as not to put undo stress on the crankshaft. In some rare instances they have to be "cut off".
Remove the blade bolt and blade, slide the adapter off the crankshaft. If it will not slide off, spray it with a good penetrating oil and let is soak for a bit then take a SMALL hammer and gently tap on the sides of it while pulling at the same time
1) Put a little anti-seize on the engine shaft where the adapter goes. This will make it easier to remove should you need to in the future
2) Align the built-in key with the key slot on the engine shaft. Slide the blade adapter on as far as it will go.
3) Put the blade on the alignment hub of the adapter (the star). Make sure that you have the blade on properly (Angled side of the cutting surface toward the bottom of the engine)
4) Install the bolt and torque to 60 ft lbs
I don't think that you received a faulty part. From what you described above, you had it installed correctly just not tight enough I used to see these all the time when I had my shop and it was due to not having enough torque on the blade bolt. The bolt will vibrate loose in no time if not tightened enough.
take the blade disc off the mower, you should have the nuts on the top of the disc for the blades, put the disc on the ground and remove the nuts on the blades.
Replace the blades with the new ones and fit the disc back under the mower
1. Remove the drive belt cover from the top of the mower
2. Tip the mower up, being careful to not go too far or the oil and fuels may spill out
3. Remove the mower blade - as I recall the bolt is 5/8" (could be 9/16") You will have to hold the blade from turning (if you have impact tools, this will be much easier)
4. Remove the blade
5. Pull the pulley out or off and remove the belt - be careful to not lose the crankshaft "woodruff" key - it's the little piece of half/moon shaped metal that keeps the pulley from spinning on the crankshaft.
6. Reverse the steps to reinstall
You MUST make sure the blade is tight when you reinstall it. Also, the blade usually fits over a couple of pins - make sure they are lined up properly and the blade is installed right-side up.
Flip the machine upside down and remove the four screws from the baseplate. Replacement should be fairly self-explanatory from there. If it's a self-propel model, note that the v-belt in the front WILL look loose normally, so it does not usually require replacement.
If you have a self propelled model, the belt you need ends in 035, if it's non self propelled it ends in 033.
