What kind of lawn mower are you changing blades on?
I would like for you to show me how do you operate
The same as any riding mower. The following is a site which explains how the work: http://www.ehow.com/how-does_4689999_rideon-lawn-mower-work.html
Turn your blades off.
take it apart and figure it out Nice answer...Not. The answer is counter-clockwise.
counterclockwise
the treads are stander so it will left for lossen and right for tighten
To change a tire on a Kubota T1460, first ensure the mower is on a flat surface and turn off the engine. Use a jack to lift the mower slightly, then remove the lug nuts with a wrench and take off the flat tire. Replace it with the new or repaired tire, hand-tighten the lug nuts, lower the mower back down, and finally, securely tighten the lug nuts in a crisscross pattern to ensure even pressure. Always consult the owner's manual for specific instructions related to your model.
The reason the mower dies when the blades are engaged can be caused by a couple of different things. One, the spindles for the blades are frozen so the blades can't turn stopping the engine. Two, the fuel system isn't allowing sufficient fuel/air flow when the engine is put under a load.
Most lawnmowers loosen to the left. At least that's how I do it.
To loosen the bolt, turn it in a counter clock-wise way. Will probably have to use a screw driver to prevent the blade from turning.
