Victa Blade Replacement

This Tutorial Demonstrates the process of replacing the blades on a Victa lawn mower,

this is similar for most other mowers.

Tools/Parts Required 

  • Replacement Blades
  • Socket Wrench - 15mm & 19mm Sockets (Mower Dependant)
  • Allen Key Set

Step 1.

Remove Spark Plug lead for safety reasons.

Step 2

Lift up the mower, with the front wheels facing skyward. This insures oil does not flow into the intake or exhaust and cause trouble later.

Step 3

Either remove the main securing bolt and remove bolts securing blades, or remove blade bolts while still attached to the mower.

Step 4

Once bolts and blades have been removed, get your new blades and line them up with the base plate. The mower should spin anticlockwise and the blades should be placed in the direction shown in the video.

Step 5

Place the bolt and plastic washer through the blade. Then secure on to the plate using the metal washer and lock nut as shown in the video.

Step 6

Make sure all bolts are firmly tight and that the blades will move when a decent force is applied. If the blades are locked too tight and you hit a rock, or another solid object, it can shear your flywheel key or shatter the con-rod in your engine causing major damage.


  1. Very instructive, thank you. I was wondering about the screwing direction of the center bolt holding the blade assembly. I understand that it is clockwise (standard) where the gyration of the blade is anti-clockwise.

  2. Extremely helpful and very clear instructions. It makes changing blades not such a dreaded task. Thanks for making the job such a lot easier.

  3. this is the best video there is it shows to lift the mower from the front, all the others shows from the side, which is not good for a 4 stroke. very well explained thank you .

  4. Hi Guys
    Follow up to my query re which blades for corvette. I finally managed to loosen the main locknut holding plate with blades attached-however the spindle to which nut is attached is turning and I cannot remove this nut. What do I do or what have I done incorrectly?

  5. G’day
    Trying to replace the 4 blades on my Corvette model. Trouble I have is that the bolts aren’t recessing into the slots, and is just free-turning when I’m trying to lock the nut. There’s no Alan key recess in the bolt head…how do I tighten the nut? I.e. how do I stop the bolt from turning (lock grip plyers aren’t reaching it)

    • Hi Ben

      If they won’t lock into the blade carrier and you cannot grip them with locking pliers it looks like the next step would be to use new bolts that have the allen key recess so you will be able to tighten them effectively

  6. Hi…I need to replace the sleeve that the blade carrier butts onto on my victa tornado 4 stroke. Is there a specific (or easiest) way to take the existing sleeve off?

  7. Hi
    I have just changed my blades on my Honda Mustang which has a victa chassis.
    Two of the blades are tightened with minimal movement but the other two are staying loose. I have taken them off and on only to have the same problem. The bolts are brand new & have the Allen key hole.
    Any ideas what I’m doing wrong? Please
