how do i remove the blade cassette on my qualcast classic 43s qx?

Yup I can – to a degree. But mine is a 35s but I's guess the instructions are the same.
1. remove the grassbox cradle – as I remember this may just be by compressing the “legs” which spring into retaining holes
2. .Remove the drive cover. This is the plastic cover on the LEFT as you stand BEHIND the machine. The screws are recessed and may even need an allen key or possibly a special screwdriver (can’t remember but the tools come with machine!)
3. remove the cassette retaining screws on both sides – these are WITHIN the cassette assembly I think – look and ye shall find!
4. . Pull the cassette out using the handle – it IS there just locate it.
5. . Replace (blades or scarifier cassette) by doing the above in reverse

Now I cannot for the life of me remember why one has to remove the drive cover, and the manual, and illustrations, provide little help. I DO remember that it became obvious once one started and I also remember that I , not an engineer, reckoned it could be SO much easier.
Cassettes? Great idea but POOR engineering!

This may or may not help. I could scan the manual but I promise it really will be of limited use
